Cellophane has a century-long history. It comes from the words cellulose and diaphane (meaning transparent) and is a trademarked name of Innovia Films in some countries, although not in the United States. Cellophane was the original clear wrapping material and was very popular before World War II.
Cellophane is water-proof but not moisture-proof which makes it better for certain applications than others. Like films in current use today, cellophane requires a coating in order to seal. Like viscose, it is derived from cellulose which usually comes from trees but can be made from other plant materials. While cellophane itself is biodegradable unlike petroleum based films, the process for making it was more cumbersome and involved toxic materials.
