THERMALLY SHRINKABLE LAMINATE FILM FOR DEEP DRAWING, PACKAGED ARTICLE, AND METHOD FOR PACKAGING OF CHEESE

摘要

Disclosed is a thermally shrinkable laminate film for deep drawing molding, which has a high carbon dioxide gas transmission rate (CO2TR) and a high ratio of the carbon dioxide gas transmission rate to the oxygen gas transmission rate (O2TR) (i.e., a CO2TR/O2TR ratio), and in which the formation of pinholes is less likely to occur. The thermally shrinkable laminate film comprises: (a) a polyamide resin composition layer comprising a polyamide resin mixture composed of 60 to 95 mass% of an aliphatic polyamide resin (A) and 5 to 40 mass% of a polyamide resin (B) having a crystal fusion heat of 5 to 40 J/g; (b) an adhesive resin layer; and (c) a heat-sealable resin layer comprising a polyolefin resin, wherein the polyamide resin composition layer (a) is laminated on the heat-sealable resin layer (c) through the adhesive resin layer (b).
