THERMALLY SHRINKABLE LAMINATE FILM FOR DEEP DRAWING, PACKAGED ARTICLE, AND METHOD FOR PACKAGING OF CHEESE |
摘要 |
The invention has for its object to provide a heat-shrinkable laminated film for deep drawing, which has an increased carbon dioxide transmission rate (CO 2 TR) and an enhanced ratio (CO 2 TR/O 2 TR) of carbon dioxide transmission rate-to-oxygen transmission rate (O 2 TR), and is less susceptible to pinholes. In the inventive heat-shrinkable laminated film for deep drawing, a polyamide resin composition layer (a) containing a polyamide resin mixture comprising 60 to 95% by mass of an aliphatic polyamide resin (A) and 5 to 40% by mass of a polyamide base resin (B) having a heat of crystalline fusion of 5 to 40 J/g is laminated onto a heat-sealing resin layer (c) containing a polyolefin resin via an adhesive resin layer (b). |
