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 (CO2TR) and an enhanced ratio (CO2TR/O2TR) of carbon dioxide transmission rate-to-oxygen transmission rate (O2TR), 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 (a) containing a polyolefin resin via an adhesive resin layer (b).
