HEAT-SHRINKABLE LAMINATED FILM

摘要

Disclosed herein is a heat-shrinkable laminated film comprising at least two layers of a mixed aliphatic polyamide resin layer (A) comprising 55 to 90 wt% of an aliphatic polyamide resin having a crystalline melting point of 175 to 240 DEG C and 45 to 10 wt% of an aliphatic polyamide resin having a crystalline melting point of from not less than 120 DEG C to less than 175 DEG C and a mixed resin layer (B) comprising a saponified ethylene-vinyl acetate copolymer as the main constituent. The heat-shrinkable laminated film of the present invention is excellent in gas barrier property and stretchability and has uniform heat-shrinkability and practicable dimensional stability. Thus, the film is suitable as a good packaging film.
