Abstract

PURPOSE: To improve an oxygen-shutting off property and an interlayer adhesion of a composite film, by a method wherein mixed resin, consisting of a predetermined amount of a saponified material of polyamide and an ethylene.vinyl acetate copolymer, and a sealing thermoplastic resin are extruded separately, and are laminated in a fused state.
CONSTITUTION: A mixed resin, consisting of 60W95wt% of a saponified material of polyamide and 40W5wt% of an ethylene.vinyl acetate copolymer, and a sealing thermoplastic resin are molten in a separate extruder. They are then extruded separately through one mouth ring, and are laminated after ozonizing a laminated surface of each resin layer in a molten state. Nylon 6, nylon 66, nylon 12, etc. can be used as the polyamide, and a suitable saponified material mixed in the polyamide is one having 10W58mol% ethylene content and 90mol or more saponification degree. A low density polyethylene, ethylene.vinyl acetate copolymer, etc. can be used as sealing thermoplastic resins.
