All about Glassine

 

Glassine is a new type of wholesale packaging that’s a big step in the fright direction for good, sustainable packaging. Glassine is basically an alternative to bags that you might need for your business and are paper based.  This is something that’s perfect for brands who need clear poly bags, and as more brands look to get rid of the plastic packaging, a lot are looking some of the more renewable, recyclable alternatives, and this is something that’s great for users to try. 

What is Glassine 

This is something you see in a lot of products already, such as the following: 

  • Snack bags and bakery good s

  • Tracing and archival paper 

  • Protection for sheets of art and also bags 

  • Apparel protection 

  • Merchandise 

This is basically a paper that’s smooth and glossy that is resistant to water, air, and grease. It is important to note though that it is resistant to water, but it is not waterproof, so if you dump some water on it, then it’ll seep on through. But it’s good for general resistance to elements as well. 



Despite the looks too, it’s made from wood pulp. Basically, the wood is first created into a pulp, similar to how any other paper products are. They’re chipped, and then the wood chips that are from the trees get cooked to help reduce the chemical bonds of the lignin in it, so the pulpers are able to separate this directly from the cellulose as well. 

However, unlike other kinds of papers, the glassine paper that’s there does require lignin that’s complete for it to work, and it must be separated from such. The slurry of pulp gets bleached, treated, and then pushed through a wire cloth, draining out the water. Then, the fibers are mat and then intertwined to create paper sheets as well. 

When it tries, the material then gets calendared or a fancy word for pressed between some of the cylinders and its’ called calendars, and then, the paper that’s created is made. However, glassine is a bit different, creating another process aptly titled supercalendering, which is basically where the paper goes through the calendaring means, and then, it’s basically heated, then cooled and pressurized, and then, it makes the fibers move in the same kind of direction. 



It’s not just the “basic pressing” but it changes the paper on a more cellular level, so that the paper capillaries are broken down in a much better way, offering more density, and less porosity, and a finish that’s more glossy. 

Different from paper 

It basically will e more resistant to water. It’s not waterproof, but basically the substrate is able to fully expand, and then contract based on the way the humidity is in the surrounding area. Supercalendering is something that is used to make the paper less susceptible to the hygroscopicity. 

It’s also more durable and a lot stronger than normal paper that’s the same weight. This is due to how dense it is compared to paper, and it has a much larger tensile strength, and bursting capability. Plus, it also comes in different weights so you can get it based on your needs. 



Finally, it’s toothless, which is basically the way a paper feels. The larger the tooth is, the rougher the paper tends to be. Glassine doesn’t have a tooth, so it won’t be abrasive, so if you have art or something delicate, this can protect it from that, making it even easier for you as well to use. Glassine is definitely a new paper that’s changing the world of packaging easily.
