Abstract

PURPOSE: To produce a composite film being excellent in a gas barrier property and a dynamical nature, by stretching a laminated film after laminating an ethylen- vinyl acetate copolymer saponified film on at least one surface of a polyester film.
CONSTITUTION: Polyester comprises dibasic acid residues and glycol residues, said dibasic acid residues being constituted such that 80mol% or more of a dibasic acid is a telephthalic acid. A film of 0.5W20μ thick comprising an ethylene-vinyl acetate copolymer saponified substance is laminated on at least one surface of non-stretched or monoaxial stretched film of said polyester being extruded by melting, said ethylene-vinyl acetate copolymer saponified substance having the following chemical conditions: A containing rate of ethylene ranges from 15W60mol%, a saponifying degree is 90% or more, and an ultimate viscosity ranges from 0.06W0.16. The film thus laminated is stretched by 2.0W6.0 times in at least one direction at a temperature of 40W180°C.
