Often mistaken for plastic, glassine is a translucent, glossy member of the paper family, providing all these benefits and more, as it is also resistant to air, moisture and grease. Generally, glassine is only made from virgin wood and the manufacturing process can be energy intensive, so we would not recommend this as the only paper solution in your roster. But if you are in need of a protective, translucent material that can give plastic a run for its money, this is a real contender.
