They are classy, durable, and can resist both moisture and liquids. The glass jars can store wax, oils, and dry canna without any damage to the products.

The following are a few more benefits that the concentrated glass jars bring for you.

Non-Reactive

The glass used for making the concentrated jars is noble in nature. It doesn't get corroded or reacts with the canna product inside. It will ensure that your product does not get contaminated.

The non-degrading nature of the concentrated glass jars also makes them a long-life solution. You can use them to store products for years without any trouble. 

The best part, the containers are very smooth and well finished. Thus, none of your products, including wax or oils, will stick with its walls.

Protective

The biggest benefit of using a glass concentrate container is the protection it offers to the canna products. The containers are usually airtight and will not allow air or moisture inside. It will also prevent direct contact of dust particles and your products.

The ones with a semi-transparent appeal can also prevent a high light from entering. Hence, the product will stay safe from almost every environmental damaging agent.

Child Safe

One common problem with most canna storage containers is that they are accessible even for children. It raises the risk of spills and unwanted exposure.

The glass concentrate jars solve this problem. Most of these come with a child-resistant lid that needs precise force to open. Usually, the lid will have a specified area where you need to press for opening them. 

Moreover, the concentrated jars were developed for concentrated canna products like resin, budder, crumble, and wax. So, the glass is strong enough to endure slight shocks and falls without spilling your products.

Looks And Durability

Safety isn&#;t the only thing that comes with concentrated glass jars, but they are also great looking. The manufacturers also provide them with multiple attractive designs. You can get them in a transparent body with a glass lid, a glass body with a plastic lid, a colored body with a colored lid, and a lot of other variants.

The product is simply brilliant for storing canna products in an eye-appealing and classy way.

Size Choices

The most amazing part about the concentrated glass is that they are highly customizable. They come in multiple different sizes and storage volumes to store your products. The child-resistant packaging product is available in 5, 6, 7, 9, and 15mL with ease. 

Some manufacturers will also have customized sizes to suit your needs. 

Final Words

When you think of airtight packaging for concentrated canna products, glass jars are a great choice. They are attractive, reusable, environment resistant, and durable. The concentrated glass jars are also excellent in locking out air or moisture that can cause odor or fungus in your products.

Plus, you have a lot of choices both in terms of design and storage capacity. You should definitely prefer them for storing and transporting your canna products. 

Glass is a material appreciated by brands and consumers. It is particularly used for the packaging of products sold in delicatessen and sweet goods (jam, honey, spreads, etc.), for local products (foie gras, traditional ready-made meals, duck confit, etc.) or catering dishes (ready-made meals, soups, desserts, etc.).

Soda-lime glass is used in the food market and is also known as Type III glass. Soda-lime glass is composed of silica, soda, limestone and cullet. This glass is widely used in the manufacture of bottles and jars. It accounts for about 90% of glass production.

Importance of food packaging: Food packaging plays a role in the processing and preservation of food. It must be safe for the food and for consumers, as well as durable to ensure the preservation of your products.

Why glass is an attractive choice: Glass is an inert material that prevents any migration between the packaging and its contents. It is therefore a very attractive food safety material. The transparency and brilliance of glass enhance the product contained. In addition, glass can be recycled over and over again. 

Why is glass an interesting choice for packaging food products?

• Neutrality: glass packaging is completely inert to its contents. There is no migration between the glass and the food. In addition, with the right accessory, glass is completely airtight. This means that glass provides a high level of safety for end customers.

• Aesthetics: Glass is popular for high-end products. Indeed, its high transparency allows consumers to visualise the contents. This quality is also used by brands to enhance their product. In addition to being transparent, glass has a shiny appearance

• Positioning: its neutrality and aesthetics make it a very popular material for packaging high-end foods. Indeed, it is perfect for enhancing its contents and guaranteeing the quality of all types of food: spreads, canned vegetables, appetizers, honey, ready meals, soups, etc.

• Hot packability: Glass is a heat resistant material. This quality is very important for foods such as jam, or ready meals that are packaged hot. Please note that type III glass does not withstand thermal shocks of more than 42°C.

• Ideal for long shelf life: thanks to its heat resistance, glass packaging can be sterilised or pasteurised. Both processes guarantee a long shelf life.

• Infinite recyclability: the collection and recycling processes for glass are perfectly controlled. Soda-lime glass contains a proportion of recycled glass. Like metal, recycled glass retains all its aesthetic and mechanical properties. According to CITEO, the recycling rate for glass was 88% in in France.

• Reusable: glass is a non-porous material that is easy to wash. Glass retains all its properties over time. Glass packaging can be reused by end consumers as well as by professionals who wish to limit their environmental impact. In the case of reuse by professionals, it will be necessary to select packaging specially designed for this type of use. To avoid creating primers that could weaken the glass, avoid overly abrasive cleaning (e.g. green side of the sponge)

From melting to packaging: the glass-making process

To make your glass packaging, silica sand, soda ash, limestone and cullet are poured into furnaces heated to a temperature of °C to create molten glass.  After the melting phase, the glass is not homogeneous and contains many gas bubbles. In order to remove these inclusions, the glass is refined, i.e. heated to a higher temperature and then to a temperature of °C for perfect glass viscosity.  The liquid glass is then fed into channels that transport the glass at the perfect temperature and viscosity to moulding machines to form the final package. A pre-defined amount of glass in the form of a drop, called a parison, is poured into a blank mould and then a finishing mould. This drop of glass can undergo two types of processes: Press-blow or blow-blow.  

The press-blow technique consists of pressing the drop of glass with a piston to create a blank, then a jet of air is injected into the preform obtained previously to give the product its final shape. This technique is preferred for the manufacture of jars and jars. The second technique is blow moulding, where the drop is compressed and then pierced.  A first blowing then allows to obtain the preform and to form the neck. Another blast of air is injected to give the package its final shape in the finishing mould. This process is preferred for the manufacture of bottles.

The annealing phase is necessary. The moulded products are heated and gradually cooled in a firing arc to a temperature of approximately 570°C to strengthen the glass. This eliminates stresses and improves its mechanical strength. The manufactured glass containers are then subjected to the necessary quality controls to guarantee the volume, neck dimensions, glass thickness, etc. Products that do not pass the quality control are completely reused as raw material and remelted.

Differences between glass and other types of packaging?

• A wide variety of closures: glass packaging can be closed by a number of different systems. Most commonly, glass jars and bottles are closed with twist-off caps. These TO caps can be low-skirted (TO), high-skirted (TOD) or extra high-skirted (TOXD). But other closures can be used: mechanical closure (for lemonade bottles or glass jars), screw-on metal caps, cork stoppers, wirehoods (sparkling wine, cider, ...), glass lids, plastic lids...

• Many types of packaging and shapes: glass can be used to produce bottles with wide or narrow openings, screw-on, crimp or snap-on/snap-off rings. The shapes of these packages are also very varied: cylindrical, straight, hexagonal, household, carafe, conical, mills, square, etc.

• Suitable for packaging many types of products: thanks to their many shapes, glass packaging can be used for liquid, viscous, solid, powdered products, etc. They can contain fresh products (yoghurt, cream), dry products (confectionery, aperitif mixes, dried mushrooms, spices, aromatics, baking aids, etc.), long-life products (jam, honey, vegetables, terrine, sauces, etc.).

• Reusability: glass packaging can be washed and reused by consumers or professionals. They have the advantage of retaining their aesthetic and mechanical properties. Few types of packaging compatible with food use can be washed and reused.

Guide to choosing the best glass packaging for your products:

The first point to consider is the type of product contained (liquid, viscous, solid, dry, ...) to select the appropriate packaging. Then, you will have to take into account the packaging process. If you need to pasteurise or sterilise your product, you will need to choose an accessory that supports this type of process. If you are packaging a product that is sensitive to light (e.g. vegetable oil), you can choose a coloured glass that will filter out UV rays. Your brand positioning should also be taken into account when choosing your packaging. If you wish to package artisanal products, it is preferable to turn to traditional jars (Weck, Le Parfait, Familia Wiss, Weck). Premium jars, on the other hand, are ideal for a high-end positioning. The quantities packed also determine the packaging selected: above 10,000 pieces, it is more interesting to switch to a twist-off jar.

• TO (twist-off) jars: twist-off jars can be used for a wide range of viscous or solid products. For solid products, jars with straight or tapered rims should be selected for ease of removal by the consumer. TO jars can be sterilisable or pasteurisable, depending on the lid chosen.

• Other closures : twist-off jars are the most common, but there are other jars with different closing systems: screw-on lids, mechanical closures, snaper lids, stand-up lids, etc. Mechanical opening jars, Familia Wiss jars and Weck jars are reusable, so you can reduce your environmental footprint. It is also a clever way to save money.  Please note that in the case of reuse, these jars are used more for artisanal or traditional products. In the case of reusable packaging, care should be taken when washing glass jars and avoiding the use of abrasive sponges that could create bumps and weaken the glass.

How does glass recycling work?

• The importance of recycling food glass : 

Recycling is important to avoid the depletion of natural resources but also to reduce waste. Like metal, glass is an infinitely recyclable material and the recycling process is very well controlled. Consumers are used to sorting glass and taking it to the appropriate collection points.

• How to recycle glass jars and bottles: steps and tips

1. Consumers should empty glass jars or bottles, remove their lids and caps before sorting and depositing them at glass collection points. 
2. Local authorities take the glass to sorting centres where the glass is partially cleaned,
3. The glass is then crushed into small pieces to become cullet and then melted down to start the glass making process,
4. The resulting cullet is fed into the glass-making process along with the other components of glass (silica, calcium and sodium) to produce new glass containers.

The advantages of glass for food packaging:

Food glass offers a unique combination of food safety and food preservation. It is a popular material for brands to enhance their contents, but also for consumers. Environmentally, glass can be recycled over and over again, and is also the material of choice for reuse.
In conclusion, food glass is an ideal choice for packaging your food products. In addition, it offers a wide variety of packaging, shapes, rings, opening diameters and accessories to best suit the products you are packaging.
