On the market today, OPP bags are produced in many different types, each bag suitable for storing different foods. Some popular types of OPP bag on the market today:

Ordinary transparent OPP bag

This is one of the quite popular OPP bags, they are made up of 2 layers of PolyPropylene film with straight direction properties. The characteristics of this type of bag are quite hard and brittle, they are used a lot to store food, medicine, and electronic components.

Tape OPP bag

OPP bags with tape have a smart bag mouth design that makes it easy to pack and preserve goods. Accordingly, one surface of the bag will be designed to be longer than the other. 

On the surface of the bag is glued a layer of tape, when packing, you just need to remove the tape and press the two sides of the bag together. This design helps you save time and also helps the bag to better preserve food and goods, preventing air and dirt from entering inside.

OPP bag with printed tape

Printed tape OPP bags have the same design and properties as tape OPP bags. But, the difference between these two bags is that the OPP bag with printed tape is added with printing. These types of printed packaging help businesses build images, show their uniqueness, and attract more customers.

Biaxial Oriented Polypropylene 

Pearl film OPP bags are manufactured from durable, flexible, impact-resistant, waterproof, and heat-resistant PP plastic material. This type of OPP packaging can preserve food and goods well. In addition, they also keep outside influences such as temperature, light, chemicals from damaging the goods inside.

5/ How to distinguish between OPP bags and PE bags?

What&#;s the difference between OPP bags and PE bags? We are sure that this is the question of many people today. Here Minh Sang compares these 2 types of packaging!

About the bag production material:

PP bags are manufactured from PP plastic granules along with some other additives. This type of bag is quite flexible, has a good heat resistance and good abrasion resistance. However, their disadvantage is that they are easily deformed.

OPP bags are composed of 2 PP films which are quite hard and brittle. This type of bag has a nylon membrane with high tensile strength. Bags with high gloss glass bring a luxurious look to the product.

The physical properties:

OPP bag has better ductility than OPP bag, so PP bags are often used to store confectionery, electronic components,&#;

OPP bags are harder and more brittle, so it is difficult to tear or puncture during use. Compared with PP bags, OPP bag has wider applicability.

About aesthetics

OPP bags have higher transparency than PP bags, so they are considered more beautiful than PP bags. In printing, using an OPP bag will result in sharper, brighter, and more durable printed products. Therefore, OPP bag is often used to make gift wrapping bags and stationery.

The choice of packaging material inevitably influences its cost, durability, effectiveness and lead times. This is true across all industries, including bulk bags. Modern bulk bags have been engineered thoroughly and stood the rigours of various tests to prove that they are a great solution for storing and transporting large quantities of material.

However, there are three types of bulk bags that have different properties as a result of their fabric. All are made from polypropylene (PP), which is a strong and durable polymer. Knowing which PP fabric to choose can make a massive difference to the value that you get out of your packaging products.

Custom Bulk Bags is a leading manufacturer and supplier of high-quality bulk bags in South Africa. We produce up to 3.5 million bulk bags per year for various customers. All of our bulk bags have a minimum safety factor rating of 5:1 and are manufactured in accordance with international regulations and standards.

What are PP, OPP and BOPP?

PP is simply the acronym for polypropylene. This plastic has many beneficial properties that make it perfectly suited to packaging and protective coatings. It is often extruded into tapes and woven to create the fabric that is used to manufacture bulk bags. However, PP can be further manipulated.

Orientated polypropylene (OPP) is a type of plastic film that is stretched in one direction, hence the microscopic fibres are aligned. This helps with strength and creates a clear plastic film. OPP is commonly used to manufacture small plastic bags, clear labels and flip files.

Biaxially orientated polypropylene (BOPP) is a plastic that is stretched in two perpendicular directions. This further improves the strength of the plastic and is highly suited to printing, which is why BOPP is often used as a clear coating or laminate over woven PP tapes used for bulk bags. BOPP is ideal for brands that need intricate printing and details on their bulk bags, such as barcodes and small labels.

Pros and cons of each polymer

PP:

• Recyclable, moisture-resistant, chemical-resistant, durable and versatile.
• Not very resistant to heat or flames and has limited printability.

OPP:

• Durable, transparent, glossy, dust-resistant and moisture-resistant.
• Difficult to stretch and are limited in their weight capacity.

BOPP:

• High tensile strength, recyclable, high dimensional stability, transparency, low electrostatic charge, high printability and resistant to oils and water.
• Low sealability. 

What is needed for your industry?

PP, OPP and BOPP are suited to specific applications. Your packaging company will be able to guide you towards the best product for your needs, but let&#;s cover some basics. PP bulk bags are your standard packaging product. They can also make good sandbags and geotextiles (or eco-bricks) due to their versatility, durability and cost-effective price point.

OPP is better suited to small packaging materials in the medical, pharmaceutical and food sectors. These packaging products don&#;t need to carry much weight, but they still need to be protective and durable. Think of sealable sandwich bags or packets for pills.

BOPP is best suited for heavier materials, such as dog food, charcoal or wood. However, when it comes to bulk bags, BOPP can be used as a laminate over the PP fabric to improve the durability of the packaging and the precision of printing.

Custom Bulk Bags manufactures an array of bulk bags that are suited to your needs. These are all based on PP fabric that is extruded and woven in-house. We offer several optional extras, including printing and customisation. For more information about our bulk bags, please contact us today.
