    摘要： A heat-shrinkable multilayer casing film, comprising at least 5 layers including an outer layer (a) comprising an aliphatic copolyamide resin, an adhesive resin layer (b), an intermediate layer (c) comprising an ethylene-vinyl acetate copolymer resin having a vinyl acetate content of 3 - 12 wt.%, an adhesive resin layer (b) and an inner layer (d) comprising an aliphatic polyamide resin disposed in an order of from the outer layer toward the inner layer; wherein the multilayer casing film has a hot-water shrinkability at 90°C of 10 - 30 % each in a longitudinal direction and a transverse direction, and the total thickness of the outer layer (a) and the inner layer (d) is 40 - 60 % of the whole thickness of the multilayer casing film. The heat-shrinkable multilayer casing film exhibits improved properties with respect to lay-flat width stability, ring-formability, and coloring irregularity while retaining various properties such as gas-barrier property, meat adhesion, heat resistance, strength, and shirrability.
