Glassine is used in many different ways, such as being used in bookbinding as a way to protect illustrations from becoming in contact with facing pages. It is also used in chemistry where it is used as a cheap weighing paper. The uses of glassine are manifold and this article shall be looking specifically at the benefits of glassine bags.
So what is glassine?
Glassine is a type of paper. This type of paper is used in many different ways. It can be used to make transparent glassine envelopes and is a very popular resource in the food industry - it is a superb material for acting as a barrier between different foodstuffs such as baked goods and strips of meat products. The manufacturing of glassine paper As an extremely smooth and thin paper, the manufacturing of glassine is a complex process. The manufacturing process uses something known as supercalendering. This is where a series of hard pressure rollers are used to form a sheet of smooth material. After the paper has been pressed and dried, it is then passed into a stack of fibre covered steel rolls that have alternating spin rotations. This makes the fibres of the paper flatten and face in the same direction.
The benefits of glassine bags
The nature of glassine gives it an almost plastic look and feel, and it can be manufactured in such a way that it is almost transparent. It also has the added benefits that it can be made with a neutral pH value. With these factors alongside the fact that it is incredibly smooth and none abrasive, bags made from glassine are used in a broad range of ways. Philately Glassine bags are commonly used by stamp collectors. These not only let the collector see swhat tamp is in the bag without having to handle it, but also helps keeping it safe from exposure to environmental factors that could be detrimental to its upkeep.
