Heat-shrinkable multilayer film

摘要

This heat-shrinkable multilayer film is characterized in that: an outer-surface layer (A), which is located at an outer surface when content has been packed, comprises a polyester-based resin; an intermediate layer (B) comprises a polyamide-based resin; an inner-surface layer (D) comprises an ethylene-based copolymer; and the adhesive strength between inner-surface layers after hot-water treatment at 80˚C is at least 10N/15mm. This polyamide-based heat-shrinkable multilayer film is provided with optimal properties for uses principally requiring strength, and has vastly improved self-welding properties required for films used to package meat products such as fresh meat and processed meat.
