The Ultimate Buyer's Guide for Purchasing Adhesive Tape Packaging Machine

Types of Pallet Wrappers

First of all, you will need to decide if you want a semi-automatic or automatic stretch wrapping machine*. Space, capital, speed, capability, and needs are all important considerations for this decision!  

Click here to get more.

A semi-automatic stretch wrapper is manually placed on a turntable and a piece of wrap is placed at the bottom of the pallet. from there, the machine will wrap the load according to your selections on the machine for load containment. The finished pallet is manually removed from the turntable and the next pallet is moved into place. 

An automatic stretch wrapper takes a pallet and automatically puts it in the wrap zone where it is wrapped based upon the settings of the control system. When completed, the pallet moves down a conveyor to the end of your packaging line. As your fully wrapped pallet completes its journey, the next pallet is automatically being conveyed into the wrap zone.

*There is also another option called "simple automation" which is available from select vendors. This form of simplified automation allows for what is called "cut and clamp capabilities" which means that your machine operators are not required to get off their fork trucks to operate the control panel. This form of automation allows the equipment operator to drop the pallet onto the wrapper while the machine pushes it onto a roller conveyor.

Pallet Wrapper Dynamics

In addition to the types of pallet wrapping machines mentioned above, there are different types of wrappers with different functionality. When trying to figure out which pallet wrapper would best suit your needs, you will want to research the following kinds of equipment: turntable wrapper, straddle wrapper, orbital wrapper, or ring straddle wrapper.

Each of these machines wraps pallets in a completely different way and each offers different variables to their load containment. Each type of machine is also meant for different applications. Reviewing the specs for each kind of machine and how the machinery is operated via video or live demonstration is highly recommended.

1. Turntable Wrapper

With this particular machine, the pallet is put on a turntable that spins while a wrap delivery system allocates the stretch wrap to the load being wrapped. The wrap delivery system generally begins at the bottom of the load and wraps up to the top and back to the bottom. Turntable wrappers are one of the most popular kinds of stretch wrapping machines and can be set up to work well with various types of applications.

2. Straddle Wrapper

With straddle stretch wrappers the load stays immobile while a wrap delivery system spins around the load being packaged. This kind of wrapper can wrap unstable, lightweight, and heavier loads and is capable of wrapping from low to high volumes.

3. Orbital Wrapper

An orbital wrapper (also known as a "ringer") wraps a pallet by going over and under the load being packaged as the load travels on a conveyor into the machine. Orbital wrappers are primarily used for packaging flattened or oddly shaped items such as pipes, rolled carpets, windows, etc.

4. Ring Straddle Wrapper

Ring straddle wrappers are fast wrappers that are generally able to wrap 200 loads per hour. These machines are often found in the toiletry and beverage industries. They are extremely specialized devices and only make up a small portion of the stretch wrapping machines currently in use.

Straddle pallet wrappers allow for the load to stay still while the wrap delivery system spins around the pallet. It then pistons up and down while the film is evenly distributed around the pallet.

How Much Does A Shrink Tunnel Cost?

There are various elements of a shrink tunnel that will affect the total purchase price of the machine. From the type and gauge of shrink film that you choose to run to the optional items you add to the machine, there are various things that can increase or decrease your total purchase price.

Below is an example that will give you a solid understanding of the total cost of a tunnel. Keep in mind, higher speeds and different options bring on different models and larger investments.

Common Shrink Tunnel Issues & Possible Fixes

As with any type of machinery, shrink tunnels and the materials run through them have common issues that can arise due to certain variables such as temperature. Here are a few of the most common problems that arise when the temperature is not optimized correctly.

&#; Flat Films Not Coming Off The Roll

&#; When layers of flat film stick together, it&#;s called &#;blocking.&#; Usually, the film has been in excessive storage temperatures, which causes it to fuse together.

&#; Jagged Seals Or Incomplete Cut-Offs

&#; Seals that look torn, incomplete, or jagged suggest that seal temperatures are too low. Try turning the heat up at 25°F increments until the film has a clean seal and sharp cut-off.

&#; Shrink Bags Take Too Long To Seal

&#; Dwell time (how long it takes for the film to seal when the seal jaws are closed) varies. If dwell times are rising, it suggests that the temperature is too low, and vice versa.

&#; Strands Known As &#;Angel Hair&#; Start Showing Up Near The Seal

&#; Strands that look like hair can appear between the sealed shrink film and the sealing mechanism. These are caused by the sealing wire or seal bar not being hot enough.

&#; Smoking Film Or Build Up

&#; Smoking and polymer build-up on a pad demonstrate excessive heat. Worn pads can also create polymer buildup and smoking. It&#;s best to reduce excessive sealing head pressure and align them.

Of course, for every problem, there is a solution and for these issues above, honing in the correct temperature will largely fix all of them.

What temperature should you store your shrink film at?

When storing your shrink film prior to use, make sure that you have a general idea of the best practices for the extremes of both summer and winter storage. During these times of the year, temperature restrictions are of utmost importance for these materials. If shrink film gets too hot, it can melt and stick to itself. If shrink film gets too cold, it can become brittle and crack.

Overall, shrink film is best stored in temperatures between 30 and 77 degrees Fahrenheit. Naturally, summer and winter are the seasons that require you to be most attentive to your storage environment.

What temperature should you run shrink film at in your heat tunnel?

The inside of your heat tunnel is an important dynamic to have locked in prior to packaging your product. The correct temperature for your product depends on which kind of substrate is being utilized. Furthermore, the appropriate heat for your product also depends on the gauge of your shrink film. More often than not, the most typical type of material run through a heat tunnel is 45 - 75 gauge PVC or polyolefin shrink film.

Let's run over a hypothetical situation that will allow you to better understand heat restrictions for your shrink films as they are passing through your heat tunnel. Say you are currently running a 75 gauge PVC shrink film:

An appropriate setting for PVC would be between 215 &#; 235 degrees Fahrenheit. Now, if you are going to use a polyolefin film with a gauge of 75, then an appropriate temperature for your heat tunnel would be about 255 &#; 275 degrees Fahrenheit. Keep in mind, these are just ballpark figures, and depending on the dynamics of your equipment, materials, and product, your actual settings may vary.

While it is technically possible to run a packaging department almost exclusively on human physical labor, most of the time it is neither a good or correct solution.

It is true that packaging machinery comes with a significant up-front financial cost, but the dividends that a quality packaging line with robust machinery can payout are worth their weight in gold. Below, we will take a look at the many benefits of using packaging machinery on your packaging line.

Production

When it comes to producing a large number of quality products, a robust packaging line can make or break a company. This is especially true if you are producing a high volume of products in a short amount of time.

Sure, you can lean heavily on manual labor, packing tables, cardboard boxes, tape, and hand film. That being said, is it really a sound investment if your volume is more than your team can manage consistently?

Investing tens, hundreds, or in some cases millions, of dollars into packaging machinery can be daunting, but the money that this machinery can save for your company over the long term can make the investment worth it.

Furthermore, with financing and leasing options, getting your hands on the packaging equipment you need to take your production and your company to the next level is easier than it has ever been in the history of packaging.

Total Cost of Ownership

The total cost of ownership is one of the most important dynamics to consider when you are weighing your options in regards to your packaging department. With the right packaging machinery, you will require a smaller labor force, therefore paying out significantly fewer wages.

Indeed, packaging machinery can come with a relatively large price tag, but when you take the total cost of ownership of a semi or fully automated packaging line and compare it to a warehouse full of manual laborers, the numbers begin to lean in the direction of machinery as the most viable option for success.

Taking the time to compare what you are paying for your labor force (not only in money and time but also in regards to hiring, firing, sick time, and vacation) to a primarily mechanized line may surprise you. Chances are, you may very well find that in reality, a machinery-driven packaging line with a few well-trained and dedicated operators is the better choice both financially and logistics-wise.

In other cases, you may find that right now is not the time to seek out the investment, but it's worth reviewing on a regular basis to make sure you are considering your overall costs and your future business goals and expectations.

Speed

Packaging machinery allows you to package more products per hour than physical labor. When the speed of getting your product to market is an important dynamic for your business, ensuring that you are running packaging machinery vs. physical labor is extremely important.

Human beings simply cannot package products as quickly or efficiently as an automated or semi-automated mechanical packaging line.

Reliability

Packaging machinery does not take sick, personal, or vacation time. While downtime may occur due to mechanical failure or a broken part, these issues are easily remedied and are few and far between when you plan your downtime. When coupled with a regular preventative maintenance program, a mechanical packaging line can save you thousands of wasted dollars and hours per year.

An Eye Towards The Future

As packaging machinery technology advances, we are going to see major leaps in speed, quality, and most importantly, automation. Packaging machinery is going to the robots and they are going to become the norm on the best packaging lines throughout the world for various reasons. The better prepared you are for this transition, the better off your company will be.

Production line automation allows companies to leverage ingenuity and efficiency without sacrificing craftsmanship or quality. With an automated production line, you never have to worry about employees getting sick, you can rest assured that production levels will remain high, and you can feel confident knowing that the end product will be made to a consistently higher standard.

Robotic packaging automation, in particular, mimics human movements to take the human being out of the process without sacrificing the yield of the process. This does not eliminate the need for good staff. Instead, it provides an opportunity to remove the repetitive, unskilled tasks that many humans find boring and unfulfilling yet are critical to meeting production needs.

In other words, robotic packaging automation provides an opportunity to maximize your staff while maintaining or increasing productivity. That&#;s a win/win situation for you, your employees, and your company.

Tips To Manage Packaging Machinery Costs

Negotiate Your Equipment Costs

When meeting with your sales rep, ask about special offers, rebates, and additional opportunities to reduce the cost of your purchase. Packaging machinery is a big investment and there may be various ways in which you can reduce the price of your purchase.

Keep It Simple

When buying a packaging machine you are likely going to get an offer from various sales reps. Unfortunately, many sales professionals will try to sell you a Cadillac when all you really need is a Toyota. When getting quotes from your chosen vendors be sure to ask about getting a base machine with no bells and whistles and only adding the options you actually need to successfully package your products.

It is also important to ask for quotes from several different manufacturers. Sometimes you can get a virtually identical offering from one company that is thousands of dollars less than their competitors despite any major difference between theirs and the other vendors' machinery.

Truth be told, sometimes you are simply paying extra for a brand name. When it comes to packaging equipment, buying a product because it is the most famous brand in the industry does not always translate to the best-packaged goods.  You may actually get a better machine from a lesser-known brand that packages your product perfectly.

Weigh Your Options

There are several dynamics for purchasing packaging machinery and their associated operation that is not a cookie-cutter solution for every business. There are some aspects of buying and running packaging machinery in which there are at least two options. One option may be right for your business and wrong for the next. These include:

1. Buying new, used, or refurbished equipment. Each of these options comes with very different price points and its own major strengths and weaknesses. As for which is right for you, this will largely depend on your budget, products, and the materials you choose to run on your equipment.
   
   
2. Hiring versus contracting technical service. For some companies with large productions and a packaging line that runs 24/7, a dedicated in-house service technician may be a good investment, but it is not the best fit or the right choice for all companies.
   
   
3. Working with a distributor versus buying direct. Each of these options has various pros and cons. Which makes the most sense for your business? That is entirely dependent upon your unique needs. Getting quotes from both a distributor and an OEM will allow you to compare the pros and cons of each and make an educated decision on which vendor is a better fit for your company.
   

Preventative Maintenance

A preventative maintenance plan is an additional cost to consider when buying packaging equipment, but it will save you thousands of dollars. When parts wear out, they can cause breakdowns that may result in extensive downtime and lead to highly costly repairs. If you are on top of regular maintenance, you will reduce the risk of more damage.

Damage may occur to other parts of your machinery when a worn-out part fails, let alone the risk of injury to your workforce. A regular preventative maintenance plan will greatly reduce downtime, keep your machinery running at peak performance and ensure quick repairs and service calls.

Try Different Material Formulations

A different material formulation may reduce your cost on the machinery that runs it. IE: stretch wrappers and shrink machinery. What many companies often overlook is that there could be more than one kind of material that works for a particular product.

Get A Machinery Analysis

Bring in a rep from a couple of different vendors and have them run an analysis of your current packaging line. This will give both of you a large collection of valuable information about your particular packaging processes such as your current equipment, materials, and procedures. This information will allow you and your rep to find ways to improve upon your current processes before upgrading to new machinery.

It is important to identify some specifics about your product to be packaged before buying a piece of packaging machinery. For example, the materials that you will be running on your line are an important consideration when planning to buy new equipment.

If you are going to be buying shrink film machinery, you will want to look at all the different kinds of shrink film as well as the various gauges of films that are available. Choosing the wrong type, gauge, and size of the film can cost your business thousands of dollars over time.

Some of the packaging considerations you&#;ll need to be aware of include:

• What type of product you are packaging
• The product&#;s weight, shape, and dimensions
• Your objectives for color and labeling
• Whether the film can be printed to meet your needs
• How the product will be packaged into the flexible film (manually or via machine, and what type of machine)
• The product&#;s journey from creation to shipment to the shelf and beyond
• Whether it will be handled often and/or subject to rough handling
• The types of climates/environments it will experience
• Whether it requires specific film additives to keep it fresh (e.g., oxygen or moisture barrier)
• Requirements for anti-tampering and security of the finished good

Key Consideration: Working With A Distributor VS. Buying Direct

When you are trying to figure out where you should buy your packaging machinery from, choosing to go direct to the manufacturer is a common choice. After all, who knows their machinery better than the people who are building said machines? You can be sure that the manufacturer knows their equipment inside and out. As such, they should be able to answer your most discerning questions.

That being said, the manufacturer will obviously be biased when answering questions like "which is the best brand of packaging machinery to buy" or "which manufacturer offers the best service"?

Now, just as there are various ups and downs when buying from an OEM, so it is with a distributor. From the cost of goods to customer service and quality in repair work, distributors have their strengths and weaknesses.

Depending on various factors including your geographical location, budget restraints, and other dynamics such as your production line's current infrastructure, a distributor may or may not be the best choice for your company.

There is an absolute myriad of considerations when choosing packaging equipment and materials are one of the most important items to consider. In addition to packaging machinery and materials, the environment and atmosphere also are important dynamics to ponder. Working with a distributor will allow you to review a plethora of options and they will be able to help you acquire the right information, advice, and products for your needs.

Key Consideration: Extreme Temperatures

Extreme heat or cold must be offset by heating or cooling systems where extreme temperatures are the norm. Whether this means you live in a place where it is always one extreme or the next, or if you live in an area that can see both extremes throughout the year, ensuring that you have the proper heating and cooling systems in place is something to take seriously.

Key Consideration: Environmental Concerns

When it comes to the environment and packaging machinery, one thing is for sure. You do not want to run pneumatic machinery. Pneumatic technology is not only extremely outdated, but it is also bad for the environment as it uses an excessive amount of electricity.

Some machines have completely eliminated pneumatic components all together which results in huge cost savings as compressed air is one of the costliest utilities in a plant.

Benefits of using non-pneumatic machinery include:

• Top-level performance with light gauge films, as well as, PE films.
• No Product/No Bag. So, you&#;re not disposing of the material.
• 10-15% film savings on average.
• Energy regeneration with every cycle.

Since air cylinders wear, eliminating pneumatics will reduce purchasing replacements and the disposal of them as well. Some non-pneumatic machines also offer what is called &#;servo technology&#; which does not require you to add additional floor space and multiple conveyors to get the correct spacing between products.

Other machines also offer what is known as &#;lean technology&#; which eliminates film breaks. This means you don&#;t have to re-wrap loads and throw extra material away. Typically, machines with lean technology use less material with a special metered film delivery system.

In addition to negating or removing pneumatic technology from your packaging line, being sure to run environmentally friendly materials is also an important consideration.

While much of the metals that make up packaging machinery can be recycled, certain materials can not or simply are not recycled.

When choosing materials for your packaging it is important to consider using flexible packaging materials like shrink film and stretch film in place of high carbon footprint items such as glass, metal, and cardboard.

While also being considerably cheaper than these other materials, shrink film and stretch film are in fact completely recyclable. And with a significantly lower carbon footprint than the aforementioned alternatives, flexible packaging materials are in fact a far better choice for the environment.

Key Consideration: Moving Your Production Line

Depending on the types of machinery you are running and how said equipment is laid out, it would be wise to create a plan for moving the right equipment at the right time. Depending on the size, electrical requirements, physical location on your line, and weight of your machinery, some planning ahead of time is an important dynamic of this process.

Reaching out to your packaging machinery and materials representative to help you formulate a plan based on the dynamics above will allow you to take a preemptive strike against unnecessary or repetitive actions during the transportation and installation of your machinery in its new location.

Depending on the flow of your packaging line, certain machinery should be installed first to ensure an efficient and timely installation. As for which machine you should move first, well, this is case sensitive for every business and should be decided by you and your technical service contact.

Key Consideration: Should You Buy Or Lease Your Machinery?

Buying new machinery is a big investment for many companies and oftentimes buyers are unsure or uneducated about the process. One very important consideration to think of right off the bat is, should you buy or lease the machinery you are planning to acquire?

The truth is neither option is one size fits all. Each has its own pros and cons and a different set of applications and line dynamics that would suggest one superior to the other. Ultimately your unique needs, layout, and budget will determine which option is best for your business.

There are however some considerations to ponder that will help you to decide which option is best for your packaging line and the unique applications in which it is involved. So with that in mind, let's review a few key elements of choosing to buy or lease your packaging machinery.

1. Focus on Your Overall Needs and Time frame.

Capital investments should be made strategically and with the future in mind. Some of the things you'll want to consider when vetting leasing new packaging machinery over financing include how much you plan to use the machinery, how many machines you will be looking to acquire, potential investors in your business, and last but not least, your balance sheets.

2. What is Your Budget?

Does it make more sense to buy your machinery outright or do you need to start out with leasing based on your budget? In evaluating/making a purchasing decision on equipment, people sometimes confuse the ability to justify the purchase with the ability to pay for the purchase. The ability to justify the purchase (ROI) is based on a business decision that the payback meets your requirements for investment.

3. What Type of Technology Do You Need?

If you want to have the best machinery on the market, you may have to do a little extra digging to find newer technologies that offer the best lease options for your business. That isn't to say that they won't be available, it just may take some extra legwork and research. Therefore, having a supplier that has experience in equipment leasing within the packaging industry is important.

How To Choose A Packaging Machinery And Materials Supplier:

When it comes to choosing a supplier for your packaging materials and machinery, it is important to do your homework and ask yourself a few questions. You should investigate at least three different suppliers and learn about several important dynamics from each of them.

Location

It is a good idea to choose a packaging machinery supplier who is relatively close to your geographical location or can easily travel to you. This will have an impact on your business when there is a need for repairs or emergency service for your equipment. Pick a supplier who is in another country and you may find yourself dead in the water for days on end. Choosing a supplier with technicians who are local is always a smart idea. When it comes to your materials, you don't have to be as worried about the physical location as most supplies can be shipped timely.

Technicians

It is important to choose a packaging machine supplier with experienced and certified technicians who are professionally trained to work on your packaging equipment. Without the proper certifications, you are taking a chance with your equipment. You could end up paying big when risking service with non-certified techs.

Customer Service

It may be tempting to source the cheapest packaging materials in an attempt to save money, but if you buy from a company with poor customer service, you may end up losing the anticipated savings anyway. Poor service often means lost dollars. Check out reviews of each vendor and if possible, reach out to current customers and ask about their vendor's customer service and if they would recommend buying from them.

Cost

There is an old saying in the packaging industry and that is "shrink film is shrink film". While there are some brands with flashy marketing and sales gimmicks with a premium price, chances are, there are several less costly alternatives that are of equal quality. If you are looking for comparisons, there are generally low-cost films that have lower clarity and higher-cost films that will shine more and have better clarity. Choosing an inexpensive film may cost you in shelf presence.

Snake oil and elevator pitches can blur the line between reality and illusion. At the end of the day, you will want to purchase from an honest supplier who carries multiple offerings at different price points and provides superior customer service.

Parts

Depending on how often your machinery is running, your downtime due to repair needs or emergency service will vary. As time is money, it is important to ask your machine supplier about lead times, parts availability, and preventative maintenance programs.

Ask each potential vendor what their average response times for emergency calls are. In most cases, it should not be more than 24-48 hours.

Which Packaging Materials Should You Use?

Different types of machinery require different types of materials and utilize different amounts of materials based on the make and model of equipment. For example, while you can save money upfront by purchasing a manual L-Bar Sealer, your cost of goods will likely be higher as a more expensive automatic sealer will generally use less material than the manual machine because the machine will generally be optimized to do so.

That being said, the quantity of product that you will be producing must also be taken into consideration. An automatic sealer won't be the right machine for a small business that is only running a couple of thousand items or less each week.

Zhongfu Packaging supply professional and honest service.

This is due to the fact that each model is designed to work with specific maximum and minimum capabilities and materials. Every machine is different. Your packaging line's unique needs must be taken into consideration when choosing the appropriate machine for your application. This can result in higher production costs if your choice of machinery cannot run thinner gauge shrink film. Using thinner gauges of shrink film can result in significant cost savings.

Conclusion:

Buying packaging machinery is a major investment. The various dynamics of choosing machinery include; safety, budget, physical layout, electrical supply, materials, and a whole host of considerations that can make your head spin.

When moving forward with the buying process it is important to start by reviewing the appropriate KPIs with an emphasis on safety first. Next, you will want to be sure to complete the packaging machinery pre-investment checklist. After filling out the information in this valuable tool and getting your results back, you will want to move on to getting quotes from at least two or three vendors.

Getting an analysis of your packaging department and collecting data on your current machinery, manual labor, materials, physical footprint, electrical requirements, production levels, types of products and the other important dynamics of running a safe and productive packaging line is key.

Once you have been able to fully analyze every aspect of your packaging line, asking for quotes from each of the vendors you are giving an opportunity to quote will provide you with peace of mind that you are going get the best deal and receive the best of what each vendor has to offer.

In addition to requesting information and pricing on the packaging machinery you are looking to purchase, be sure to also acquire information about the cost of service, installation, any training available, supply, and repairs. Ideally, you should consider getting a quote for a long-term preventative maintenance plan as this type of program will ensure that your machinery is always running at peak performance and that downtime will be limited when it does occur.

Once you have chosen a vendor to buy from, meeting with your representative and reviewing the machinery offerings that they have will allow you to open a conversation about pricing. Here you can ask about special offers, rebates, additional options, leasing versus buying, and other related dynamics that will help you to get the best price and best plan implemented for your specific budgetary restraints and packaging line needs.

Finally, it would do you well to schedule quarterly, bi-annual or annual meetings for review with your chosen vendor's sales representative and one of their maintenance technicians.

This will allow you to review data from one meeting to the next and identify places where your machinery and materials could be improved upon to further reduce your cost of production, increase speed to market, create greater efficiency and produce a superior performance on your packaging lines KPIs.

Once you have purchased your new machinery and have worked with your chosen vendor to install the machinery, train your operators, and all else has been said and done, be sure to schedule your first review before your representative leaves your building.

1.What Is A Case Sealer?

A case sealer is mostly used in packaging industry or industries where products are packed with sensitive care. A case sealer is basically a packaging equipment which is used to pack a carton or box in a highly efficient manner. A carton is placed on the conveyor and the tape rollers roll on both sides of the carton.

In this manner, the carton gets sealed from all the sides. A carton sealer ensures safe travelling of products even if it is to be delivered to a longer distance. This type of sealing reduces human efforts to a large level and gives quality packaging.

2.What Are the Application Of Case Sealers?

Case sealer also called carton case sealer, is most popularly used in carton packaging industry where large numbers are to be packed in limited time. Traditionally, this method was done by the operator himself, but it was much time consuming and also the packaging was not done in a proper manner. Case sealer has now provided packaging industry a great benefit in clean carton packaging of products.

Other than packaging industry, all industries like food, manufacturing, goods, wood, cosmetic, chemical, pharmaceutical and paper are packing their products in cartons or boxes are now focused on using these case sealers for their packaging process. Case sealer increase productivity in an exponential manner and helps industries to become more economically stronger.

3.What Are the Working Principles Of the Case Sealer?

The working principle of a case sealer is not as complex as other sealing options. It only follows the few procedures.

• Initially all the products are kept inside the carton or box and then sent to the conveyor of a case sealer.

• All external and internal parameters including power, conveyor speed, tape rolling speed and other are maintained for proper sealing.

• The carton is then placed on the conveyor manually and then it automatically travels to the path towards the machine.

• As the carton enters the sealing area, both up and down tape sealing rollers roll on the surface of it and seal the carton from upside down.

• The motor then drives the carton out of the system and in this way the sealed carton is received at the end of conveyor system.

• In this simple procedure, highly efficient sealing is performed on carton with precision and accuracy.

4.What Are the Main Components Of A Case Sealer?

The main components present in a case sealer are

• Tape Dispensers

This is the heart of a case sealer because it holds the main sealing tape in it and dispenses over the products. The tape dispenser rolls over the carton when it is feeded to the system. The important feature of a tape dispenser is that it only releases a desired amount of tape according to the size of carton.

Tape dispensers are available in different width and sizes ranging from 25mm to 100mm for an overlap tape of up to 70 mm

S.NO Tape Width Tape Range Tape Overlap 1 30mm 25-30mm 50mm 2 50mm 38-50mm 50 or 70mm 3 100mm 65-100m 70mm

• Pillars

Pillars are the one which forms the assembly of a case sealer. They are of different size and width according to their placements. They are also incorporated with air cylinders and gas springs.

• Tape Alarm

Tape alarm is an indication unit that monitors and supervises the process of sealing. This system monitors the knife and roller movement with its photoelectric eyes. Whenever some mishap or warning occurs, the tape alarm generates an alarm both in audio and video form. In the meantime, it also holds the rest of process. It indicates following warnings.

• If the roller tape gets empty.
• If the roller tape is about to get empty
• If there is no tape on the roller
• If the tape is not properly cut and the roller still pulls out tape.
• Motors

For ensuring the movement of cartons or boxes and properly sealing, some motor driven units are their which are moved using motors. Also, the conveyor system is moved using these motors.

• Conveyor System

Conveyor systems are there in a case sealer machine for proper in and out of a carton or box. These conveyors easily make delivery of boxes to the system and inline the system.

5.What Are the Features Of the Case Sealer?

• Packaging Range

Case sealers are highly versatile that they provide a wide range of packaging standards. It can be customized to any range according to the length, width and height of the carton or box. No matter what material the box is made up of, a case sealer can seal it with high perfection and precision.

• Common Power Input

One of the most important features of a case sealer is that it does not require any special type of input power supply. It can be plugged in any of the range of voltage available in the global world.

• Customized Conveyor Length

Another feature of a case sealer is that it is not utilized for only a single length box or carton. The input conveyor and whole system can be adjusted according to the packaging box. The conveyor speed and movement is also controlled according to that particular situation.

• Machine Structure

Most of the case sealers are made up of stainless steel due to which they are highly durable and last for a longer period. The environmental condition does not harm the sealer that much due to its composite body structure.

• Machine Working Speed

Last but one of the unique features of a case sealer is their speedy packaging. The rate of products sealed in a prescribed time is much higher than done by traditional sealing methods. This increases the productivity of an industry and allows producing number of cartons in an hour without any human effort.

6.How Many Types Of Case Sealers Are Available There?

Case sealers are primarily available in two types. These types are then further divided according to the construction of machine and its application. The two types of case sealers are

• Semi-Automatic Case Sealer

In a semi-automatic case sealer, both human and machine interface are present and different stages. Initially the carton is placed by the operator and flaps all the interfaces either minor or major. Then the carton enters the system and tape sealer is applied. Also, after the sealing application the carton is manually received at the other end.

• Fully Automatic Case Sealer

While in a fully automatic case sealer, all the procedures are performed by the machine itself. Sometimes the operator only places the carton on the entrance if the machine is isolated from the rest procedures.

Otherwise, the whole product placement, flapping of carton edges, sealing, and quality check all are done by the machine itself. Also, a proper conveyor system allows the entrance and exit of cartons.

7.What Are The Differences Between Case Sealers And Case Erectors?

Some of the differences between a case sealer and case erector are

• Case Sealer Vs Case Erector

A carton or case is kept in a case sealer, here the machine folds both the top and bottom flaps of the object and seals it uniformly.

In a case erector, the carton or box first gets shaped and then flaps of all sides are sealed properly.

• Operation

The working method of case sealer is very easy as the box is pushed into the sealing system manually or by conveyors first. Here the holders present inside the system hold it and then activates both the sealing shafts. Top and bottom shafts allow the sealing of box neatly by the rolling of tape on it.

The method of case erector is entirely different. A flat cardboard is pushed into the sealing system and there it gets it actual shape. As the box or carton gets it shape, the tape is then applied to all the sides.

• Machine Parts

The main machine parts of case sealers include tape fixing roller, handwheel lock, carton positioning wheel, conveyor, conveyor table, frame, casters, switch, motor, and height adjustment handle.

A carton sealer is mostly comprised of a taping mechanism, bunch of tapes and it holders, hard metallic structure and conveyor belts.

The main machine parts of case erectors include touch screen HMI, power switch, press plate, side belt, electrical cabinet, foot pad, emergency switch, side belt width adjustment, air inlet, blank magazine, case height adjustment, protective cover, blank retainer, vacuum sucker.

Most importantly, a taping wheel is present in a case erector which is responsible to perform taping on all sides and standing shafts to make the carton or box stand from flat surface.

• Sealing Speed

3 to 5 cartons or boxes are sealed in a second while using a case sealer but in case of a case erector, the productivity increases to 5 to 7 boxes per second.

8.What Types Of Tape Materials Are Used To Seal In A Case Sealer?

Most used taping material in a case sealer are

• Box Sealing Tape

Sealing tape are easily available anywhere and are preferred to be used as a sealing option. They are used as lubricating and sealant material to combine two surfaces of any material.

A box sealing tape is a bit weaker in sealing strength as compared to adhesive tape but are more economical.

• Adhesive Tape

An adhesive material is usually a combined form of adhesive film and bonding material that joins two surfaces together with greater strength. An adhesive tape can easily be used instead of screws or ropes.

A case sealer ideally uses this type of taping material because the product must travel longer distances. An adhesive tape can also be used in low temperature conditions which makes it highly useful than other types of sealing tapes.

9.What Are the Benefits You Can Get From A Case Sealer?

There are various advantages of the case sealer that you can purchase a case sealer including increasing productivity, avoiding material waste, proper sealing position, product security, product presentation.

• Increasing Productivity

Packaging Productivity &#; photo credits: insitepackaging

Case sealers are used to increase the productivity to a large level which was near to impossible with traditional methods. Manual sealing takes a lot of time whereas automatically and within a minute a case or carton gets sealed with perfection. It directly increases the production rate on daily basis.

• Avoiding Material Wastage

Carton Waste &#; photo credits: rethink

Using a case sealer ensures that all sides of a box are proper and evenly sealed so that no material wastage takes place. A single strip is continuously applied on the whole case which also avoids multiple times application of tape. In this way the applied tape is also saved.

• Proper Sealing Position

Previously, an excess quantity of taping on sealed cartons was received. But now using a case sealer, tape is applied on proper positions within a system and no excess tape is used. In this manner sealing with efficient length and position is done.

• Product Security

A single layered sealing on cartons with consistency allows the product to be highly secured. It ensures better security of products no matter how far it must travel. A case sealer decreases pilferage rate and increase security of products during transportation.

• Product Presentation

The product which is packed in a case sealer is highly presentable in nature. It is packed in a level that the customer gets directly attracted to it and wishes to have a case sealer

• Less Damage to Products

Protection of Products &#; photo credits: shursealsecure

Using ordinary means of sealing like scissors, staplers, straps or glue has high probability of product damage. These cannot completely secure the product and in a result both worker and products loss can occur.

Case sealer on the other hand provides unbreakable sealing to case so that the product and its surrounding both get secured. Also, the repairing cost reduces to a distinct level while using a case sealer.

• Operators Safety

As the product gets secured, it reduces the chance of any accident with its motion. The employee or operator that carries the carton is completely safe and there is no chance of any injury to the operator. A case sealer also reduces human efforts, fatigue, injuries and machine breakdowns.

10.What Are The Common Faults And Their Remedies That Are Faced In A Case Sealer?

Some of the possible errors that are faced in a case sealer are

• Insufficient Sealing

The most popular error or fault that is faced in a case is of insufficient application of sealing. Due to this the packaging is not proper done and hard kneading or peeling is present which can further crack the sealing in transportation. This factor mainly arises because of the improper setting of parameters like temperature, pressure, conveyor speed etc.

This error can be removed if proper sealing pressure and conveyor is maintained and synchronized with each other.

• Edge Breaks

Another problem faced in case sealer is of shrinks or edge breaks. This problem is created because of improper sealing temperature.

The error can be rectified if the sealing temperature is maintained according to the product and tape material that must be packed.

• Wrinkles Formation

Wrinkles are formed due to the failure of sealing that is caused by static electricity. As the result case sealers applies tape with wrinkles and also the inward attraction of contents takes place.

Properly static electricity supply can minimize this problem.

• Product Contamination

There are possible scratch marks or ways that can contaminate products due to improper cleaning of parts that are present in a case sealer.

Proper parts clean schedule if done will reduce the chances of product contamination.

11.Which Factors Are Necessary To Be Noticed Before Buying A Case Sealer?

There are six important factors that should be kept under consideration before going for purchasing a case sealer

• Sealing Range

The most important factor before selecting a case sealer is to check its versatility and compatibility. Because it is not necessary that only a single sized carton is to be sealed every time. There can be different sizes according to the situation. So, the manufacturer should select the machine after complete study of whether it is compatible on uniform size or also on random sizes.

Random case sealer can give lot of productivity and economical advantage to the manufacturer. It is always a good decision to select a random case sealer rather than a uniform case sealer.

• Weight of Case

The weight handling capability of a case sealer should also be one of the important concerns for the buyer. As the products that are being packed vary in weight, it can directly affect the speed of conveyor. As a result of it poor quality taping will be performed. So, select the sealer with maximum weight bearing capacity according to production setup.

• Production Volume

A more productive machine can drastically increase the productivity of any industry. Before buying a case sealer it should be kept under consideration that how much number of cases can be sealed in a day. After complete analysis of production volume of any business right type of sealer can be selected. Anticipation of volume is an important task before selecting a case sealer.

• Labor Involvement

Machine with high automation can reduce the labor cost and increase the production cost. So, machine should be selected keeping in mind that is the labor necessary or not or fully automated machines are required.

• Size of Case

Case sealer in which the industry is interested to invest should be compatible with small to large cartons. Size is an important factor which ensures that the machine will seal number of cartons regardless of their sizes.

• Working Environment

Another important factor for considering in a case sealer is that in which environmental conditions the industry will use it. Environmental conditions can directly affect the structure of a case sealer. As in high humid conditions, case sealer made up of stainless steel are more preferred.

Likewise in normal working conditions, simple enameled steel body structured case sealer can be used. While checking the environmental conditions, machine size and its placement should also be considered according to the area available within territory.
