Cellophane and polypropylene are both used to package food and other products. As a food packaging, cellophane is easier to manipulate and costs more than polypropylene. Both products are approved by the U.S. Food and Drug Administration.
Cellophane is a paper product made from wood pulp. It was invented in 1900 and has been continuously manufactured since the 1930s. Cellophane allows moisture to pass through, preventing condensation. In addition to food packaging, cellophane is used to wrap flowers and gifts, and to make adhesive tape.
Polypropylene is a thermoplastic polymer derived from crude oil. It is used to make plastic products such as packaging containers; wrap for food and other products; and fiber products including carpet, rope and clothing. Polypropylene is stronger than cellophane but must be heat-sealed or taped to close.
Cellophane is made from plants so is biodegradable, however toxic chemicals including carbon disulfide and sulfuric acid are used in the manufacturing process. Polypropylene is a petroleum-based product that does not readily break down. Plastics can be recycled, though separating the component chemicals is not easy, and different types of plastic must be sorted before recycling.
