Title:

HEAT-SHRINKABLE MULTILAYER FILM

Document Type and Number:

WIPO Patent Application WO/2014/178379

Kind Code:

A1

Abstract:

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 having a melting point measured using differential scanning calorimetry (DSC) in accordance with JIS K7121 of 90-100˚C; and the adhesive strength between inner-surface layers after hot-water treatment at 80˚C is 0.1-3.5N/15mm. This polyamide-based heat-shrinkable multilayer film is provided with optimal properties for uses principally requiring strength, and is capable of achieving an excellent balance between self-welding properties and easy-peeling properties which is required for films used to package meat products such as fresh meat and processed meat.
