GLASSINE BAGS

Different uses for glassine bags.

'Glassine is a paper product that is resistant to grease, air and water. A special manufacturing process is required to make this type of paper, and it can be expensive because a single sheet represents a great deal of work in a paper factory. There are many uses for glassine, ranging from archival protection to laboratory work. Various paper suppliers make and sell it in a range of colors.

How it is Made

To make glassine, paper pulp is beaten to break down the fibers. The pulp is pressed into molds and allowed to dry into sheets. The sheets are pressed through hot rollers in a process called calendering, which makes the fibers lie flat and in the same direction. Glassine is considered supercalendered paper, because it is subjected to the process multiple times. The end result is a very smooth product that can be used as barrier protection from many substances.

Appearance

Basic glassine is almost transparent, with a neutral color. The color can be changed with the addition of dyes during the pulping process, and some companies also make opaque varieties using other additives. Many people prefer this product in its semi-transparent form, because it allows them to see what is lying underneath it.'
