摘要

PROBLEM TO BE SOLVED: To provide a multi-layer laminated film to be used as a lid material for container or a packaging sack excellent in the unpacking easiness, having oxygen barrier effect, and free of impairing the outside appearance caused by stringiness at the peel part, and provide a package container using the film as lid material and also the packaging sack.;SOLUTION: The multi-layer laminated film has a seal layer A and base material layers B, C, D laminated thereon one over another, wherein the seal layer A consists of a mixture of high-density polyethylene and polypropylene, and the layer thickness is 1-20 μm. Further the base material layer B consists of polyethylene or ethylene-propylene copolymer and the layer thickness is 5-50 μm, while the base material layer C consists of ethylene-maleic anhydride graft copolymer or propylene-maleic anhydride graft copolymer and the layer thickness is 1-20 μm, and the base material layer D consists of ethylene-vinylalcohol copolymer and the layer thickness is 5-30 μm.;COPYRIGHT: (C)2009,JPO&INPIT
