Process for producing coextruded film of polypropylene, polypropylene blend, and nylon

摘要

A novel coextruded plastic film has as an adhesive layer between polypropylene and nylon layers, a blend of polypropylene and a graft copolymer of maleic anhydride onto a polypropylene backbone, the graft copolymer having been produced in a reaction carried out at a temperature of from about 80° C. up to about 10° C. below the melting point of the polypropylene.
