Abstract

PURPOSE: To obtain film superior in terms of strength, gas barrier property, contraction, heat-sealing property, flexibility and moisture-proofness by ozonizing resin layer containing polyamide resin and ethylene vinyl acetate copolymer saponified substance and thermoplastic resin layer, and elongating said layers biaxially after lamination.
CONSTITUTION: Blended resin layer (B) containing 94W40wt% of polyamide resin and 5W60wt% of ethylene vinyl acetate copolymer saponified substance and thermoplastic resin layer for sealing (A) are extruded from either flat die or ring die on coextrusion method in such manner that the thickness of blended resin layer (B) may be 10W70% of the total thickness. Then the adhesion faces of resin layers A, B still in a molten condition are ozonized and laminated. Coextruded laminated sheet thus obtained is cooled and is elongated biaxially 1.2W4.5 times as much both lengthwise and crosswise at 65W130°C.
