As a polymer made from cellulose, a natural compound found in plants, DuPont Cellophane happened to be fully biodegradable. The packaging material was not perfect, however, since the process of producing it created a number of pollutants as byproducts.
DuPont stopped making Cellophane in 1986 in favor of newer materials like Mylar, but other companies continue to sell Cellophane, marketing it as a biodegradable consumer package in line with modern "green" consumer values.
