Glassine Envelopes for Lepidoptera - Butterfly Collecting

Butterfly collecting (Lepidoptera) and insect collecting is a favored way of contact with the beauty of nature. Glassine envelopes for butterfly collecting are the new science as evidenced by the Naturalis Biodiversity Center, which has announced that it will permanently store its Lepidoptera collection in glassine envelopes.

Why glassine? Glassine is a smooth, translucent paper made from a manufacturing process called supercalendering. The paper pulp is beaten to break down the fibers. After pressing and drying, the paper web is passed through a stack of hard pressure rollers. This pressing of the paper fibers in the machine buffs the paper, producing a very smooth, enamel-like and acid-free surface. And the clarity of the glassine allows good visibility of the contents.
