Heat-shrinkable multilayer film

A heat-shrinkable multilayer film consisting of:

• an outer surface layer including an aromatic polyester resin;
• a first adhesive resin;
• an intermediate layer including a polyamide resin;
• a barrier layer comprising EVOH;
• a second adhesive resin;
• and
• an inner surface layer including a sealable resin comprising a polyethylene resin;
• wherein
• the polyamide resin constituting the intermediate layer is a mixture of 88 to 86 wt. % of nylon 6-66 and 12 to 14 wt. % of nylon 6I-6T;
• a total thickness of the heat-shrinkable multilayer film is from 95 to 160 μm;
• a thickness of the intermediate layer including the polyamide resin is from 17 to 47 μm;
• a thickness of the inner surface layer is 55 μm to 87 μm;
• a ratio of the thickness of the intermediate layer including the polyamide resin to the total thickness of the heat-shrinkable multilayer film is from 18 to 29%, and
• the heat-shrinkable multilayer film being laminated in the order of the outer surface layer comprising the aromatic polyester resin, the first adhesive resin, the intermediate layer comprising the polyamide resin, the barrier layer comprising the EVOH, the second adhesive resin, and the inner surface layer comprising the polyethylene resin.
