This beaten pulp is then squeezed into molds and set to dry into sheets. These sheets are then rolled through hot rollers. This is calendering. Calendering makes the plup fibers in the sheet lie flat and in the same direction. Glassine is known as supercalendered paper. This is because it goes tough the calendering process multiple times. The final product is a extreamly smooth paper which can be used as barrier protection from many kinds of gease, air, and liquids.

Yes, glassine bags are biodegradable. Glassine is manufactured by a process called calendering. After pulping and drying sheets are passed through rollers so that the paper fibers are flattened out and facing in the same direction.
