What is the difference between Polypropylene and Cellophane?
Polypropylene is a type of plastic generated from by-products of the petrochemical industry. Cello is produced from wood pulp. Polypropylene is a moisture barrier, while Cellulose film needs coatings for barrier properties. Cellulose films can vary the coating to have differing moisture barriers. Polypropylene is more flexible than cellophane.
