Real Cello Bags vs Fake: Know the Difference

Many retailers sell "cello bags" made from cheap Cast Polypropylene (CPP)—but these lack the strength, clarity, and food-safe barrier protection of true cellophane bags. Prism Pak sells only genuine BOPP and Cellophane cello bags, trusted by bakeries, food manufacturers, and craft businesses for superior product protection.

Why it matters: Real BOPP bags keep food fresher longer, resist punctures, and meet FDA food-safe standards. Cheap CPP bags stretch, tear easily, and compromise product quality.
