COEXTRUSION MULTILAYER FILM FOR DEEP DRAW PACKAGING

摘要

PROBLEM TO BE SOLVED: To provide a packaging material which has high rigidity and curling resistance as a deep draw packaging body and is thin without impairing transparency and glossiness, and to provide a packaging body using the same.SOLUTION: A coextrusion multilayer film for deep draw molding has at least three layers of a polyethylene terephthalate glycol (PETG) resin layer on an outer layer, a gas barrier layer on an intermediate layer, and an easy peel layer formed of a polyolefin resin on an inner layer, has the total thickness of the films of 40 μm or more and less than 120 μm, and has a ratio of the thickness of the PETG resin layer to the total thickness of the films of more than 60% and 80% or less.SELECTED DRAWING: None
