Glassine paper bags are one of the most useful types of packaging in the food industry. These bags are manufactured with paper-based material and are treated with several mechanical and chemical processes to get a clean and opaque sheet of paper.

At Custom Boxes Market, you can find several printing options that will give an alluring look to the bags. You can use these printed bags to promote your company in a distinct way. Regardless of the size of the order and shape of the bags, you will find remarkable designs and affordable rates with us. Let’s see how this amazing sheet of paper will help across different industries.

What Is Glassine Paper?

It is a smooth paper that has a semi-transparent appearance and a glossy texture. The paper sheets undergo supercalendaring, which gives a smooth and dense surface to the packaging paper. In the process of calendaring, heavy rollers are used to smooth the surface of the paper. This dense sheet of paper is used to get custom glassine paper envelopes and bags. Some of the amazing features that glassine paper bags have are:

Smooth Texture

Glassine has a premium appearance due to its silky and smooth surface. The process of super calendaring is the reason for this smooth texture. In this process, the paper is passed through heated rollers that apply pressure to compress the fiber. The finishing on this custom food paper makes it a perfect material to be printed with the design of your brand.

Transparency

Glassine bags for food packaging are transparent in appearance, and you can partially see what is inside the bags. This feature of the bags makes them an ideal option to wrap food items, and they are a perfect option for retail packaging.

Durability

Although these custom paper bags are thin and lightweight, they have enough durability to resist tearing. Moisture and grease remain at bay due to the durability. The dense structure of the bags prevents contaminants from reaching the packed products.

Non-porous

Glassine packaging bags are non-porous due to the tightly woven fibers present in them. This non-porous surface of the bags makes them non-absorbent to liquids. If you want to pack products that need to be kept crispy, the use of glassine bags is an excellent option.

Tensile Strength

Glassine paper has a moderate tensile strength, so you can stretch the paper slightly under tension. This feature gives you bags that are not easy to tear during normal handling and folding. The paper can be used as an alternative to bread paper bags to keep the spongy bread fresh and appetizing.

pH Neutral

Glassine has a neutral pH that makes it an excellent option. This feature of the bags makes them an excellent option for the packaging of archival items. This is because the acidic packaging can cause yellowing and fading of the material. This yellowing and fading deteriorate the documents or photos over time. By using biodegradable glassine paper bags, you can prevent this fading and chemical deterioration.

Non-Reactive Surface 

As the surface of glassine sheets is neutral, it does not react with inks or stored items. So if you want to store collectables, then these paper bags are an excellent choice. You can also retain the quality of artwork or pharmaceutical products by wrapping them in glassine paper sheet bags.

Grease Resistance

Glassine wax paper bags, eco-friendly packaging, are naturally resistant to grease and oils, and you do not have to apply any additional coatings on them. The design and non-absorbent structure make them a perfect option for baked goods and chocolate. Just like wax paper bags, glassine bags can also be used to pack butter.

Chemical Stability

The best part about the paper is that it retains its chemical structure under various conditions. This paper does not break or release harmful substances. For reliable and food-safe packaging, we use eco-friendly glassine bags. 

Materials Used In Glassine Paper Bags

We use refined wood pulp to manufacture the bags. This pulp consists of cellulose fibers that are extracted from trees and are extensively processed to remove impurities, such as lignin and resins. The resulting paper is pure and smooth, having a semi-transparent and resistant surface.

We refine the fiber by supercalendaring to obtain tightly woven fibers. This process provides a smooth texture and high density to glassy bags that have non-porous and pH-neutral qualities. Aside from the use of primary materials, we also combine some of the supporting substrates:

Kraft Paper

Kraft paper is added as a backing paper or extra layer to give additional strength and density to the bags. Bleached or unbleached, both types of kraft material can be used. It has sturdiness and a natural brown color that gives a catchy appearance to the bags. The same features are the reason why we sometimes use Kraft as a backing paper.

Biodegradable Adhesives

We use biodegradable adhesives to seal the bags and to attach the handles. These adhesives are plate-based and are used due to their natural ability to decompose without leaving any toxic residue behind.

Natural Fibers

Natural fibers are used for string closures and reinforcements. These are made with renewable resources and biodegradable resources. The use of natural fibers keeps the bags biodegradable and strong without the use of any plastic. Some of the natural fibers used for compostable glassine bags are as follows:

• Jute
• Cotton
• Hemp

Printing On Glassine Paper

Getting printed glassine paper bags is a bit challenging due to their smooth and non-porous surface. But printing is one of the essential components of any custom packaging, which is why we use advanced processes to give a promotional look to the bags:

• Flexographic Printing 
• Screen Printing 
• UV Printing (useful due to easy application on non-absorbent surfaces)
• Offset Printing (can be done with special inks only)

To print artwork on glass sheets, we have to use inks with low viscosity and quick drying. Water and soy-based inks are the best options for this.

Coatings Used on Glassine Bags

The paper is already resistant to grease and water. That is why it can be used without coatings. However, certain brands offer coatings that can enhance the resistance qualities of glassine. You can choose the options considering the features of the bags you want to enhance:

• Wax Coating: This coating enhances the moisture and grease resistance.
• Silicone Coating: If you want to use glassine pages at high temperatures and make them release-friendly, then silicone coating is a good option.
• Biopolymer Coatings: For a compostable or biodegradable protection.
• Water-based Coatings: To enhance the printability without harming recyclability.
