Wiki:
Glassine is a very thin and smooth paper that is air and water resistant.[citation needed] It is translucent unless dyes are added to color it or make it opaque. It is manufactured by supercalendering: after pressing and drying, the paper web is passed through a stack of alternating steel and fiber-covered rolls called a supercalender at the end of the paper machine such that the paper fibres flatten facing in the same direction.
