Description
Pro-fax RP323M is a barefoot polypropylene random copolymer available in pellet form. This resin is typically used in cast film packaging applications. Typical properties of cast film made with this resin are excellent clarity and gloss, as well as improved cold temperature impact resistance and broader heat seal range compared to homopolymer polypropylene.
