MULTILAYER FILM, PACKAGING MATERIAL USING THE SAME, AND PACKAGE

摘要

PROBLEM TO BE SOLVED: To provide a packaging material made of a laminated film in which a content to be packaged can maintain high barrier properties without being affected by an adverse influence of an eluted substance generated from the material itself and to provide a package using the material. SOLUTION: The multilayer film comprises at least two layers containing a layer made of a cyclic polyolefin resin single substance and a resin layer adjacent to the previous layer. In this film, the resin layer adjacent to the resin layer contains 50% or more of a linear low-density polyethylene resin single substance or a linear low-density polyethylene resin. The multilayer comprises the resin layer having a density of 0.920 or less or a mixed resin layer of the cyclic polyolefin resin and a polyolefin resin different from the resin. The packaging material using the multilayer film is provided. The packaging using the material is provided. COPYRIGHT: (C)2003,JPO
