Title: HEAT SHRINKABLE MULTILAYER FILM
Abstract:
The present invention is a heat shrinkable multilayer film which is composed of at least three layers including an outer surface layer that is formed from a thermoplastic resin, an intermediate layer that is formed from a polyamide resin, and an inner surface layer that is formed from a sealable resin, and which is configured such that: the total thickness is 95-160 μm; the thickness of the intermediate layer that is formed from a polyamide resin is 17-47 μm; the thickness of the inner surface layer is 55 μm or more; and the proportion of the thickness of the intermediate layer that is formed from a polyamide resin to the total thickness is 18-29%. A heat shrinkable multilayer film according to the present invention has high strength and excellent flexibility. Consequently, a heat shrinkable multilayer film according to the present invention is easily formed by means of stretching, and is suitable for use as various packaging materials including a packaging material for food.
