发明名称 熱収縮性延伸積層フィルム、並びに、これを備えるトップシール包装体及びピローシュリンク包装体
摘要 PROBLEM TO BE SOLVED: To provide a heat shrinkable oriented multilayer film in which the deformation of the package in a heat shrinkage process can be controlled when the package is wrapped, and which has superior deformation recovery after packaging.SOLUTION: The heat shrinkable oriented multilayer film includes: a surface (A) including an ethylene-α-olefin copolymer; an adhesive layer (B); a core layer (C) including an aromatic polyamide based copolymer; an adhesive layer (D); and a surface layer (E) including a propylene based copolymer in this order. In the heat shrinkable oriented multilayer film, the density of the ethylene-α-olefin copolymer is 0.910-0.935 g/cm, the melt flow rate of the ethylene-α-olefin copolymer is 1.0-3.0 g/10 minutes at 190°C, and in the loading condition of 2.16 kgf, and the ratio of the thickness of the surface (A) to the thickness of the entire heat shrinkable oriented multilayer film is 50-80%.
