EASY OPENING COMPOSITE FILM

摘要

PURPOSE: To provide a composite film excellent in heat sealability, easy to peel at a time of use and capable of being suitably used in gas packing. CONSTITUTION: An easy opening composite film is obtained by forming a heat seal layer from an ionomer resin and providing a polyolefin resin layer peelable from the ionomer resin on the heat seal layer and arranging a saponified ethylene/vinyl acetate copolymer other than the heat seal layer and characterized by that the melt flow rate of the ionomer resin layer is 1.0-10g/10min and the thickness therof is 1-10μm.
