Abstract

PURPOSE: To obtain the film having excellent heat-shrinkable property and heat sealing property in a laminated product constituted of two polymer films by making a heat-shrinking rate at 120°C of the propylene α-olefin copolymer film, which contains 50wt% or more of constitutional propylene unit, twice or more of the heat-shrinking rate others.
CONSTITUTION: In the film, which consists of a mixture of a propylene polymer and at least two kinds of 2W10C (except 3 carbon number) α-olefin copolymers, which can be copolymerized, having different carbon number and contains 50wt% or more of the constitutional propylene unit, the heat-shrinking rate at 120°C in either of the lateral or vertical direction of the film is made twice or more of the heat-shrinking rates in other directins. Accordingly, the heat-shrinkable film, which has anisotropy, being excellent in heat-shrinkable property, heat sealing property and printing property and suitable to a sheath material to be stuck onto the outer surface of a material to be packed, can be obtained.
