ABSTRACT:
A polyolefin resin composition comprises (A) 10 to 100 wt % of a propylene/α-olefin random copolymer obtained by random copolymerization of propylene and a C2to C20α-olefin, and having a melting point as measured by DSC of 40 to 115° C. and an α-olefin content of 5 to 70 mol %, (B) 0 to 90 wt % of a random propylene resin having a melting point as measured by DSC of 120 to 150° C., and (C) an alicyclic saturated hydrocarbon resin having a glass transition point of 20 to 100° C. and a number average molecular weight of 1200 or less, the component (C) being used in an amount of 5 to 100 weight parts per 100 weight parts of the total amount of the components (A) and (B). A single-layer or multilayer film obtained from the polyolefin resin composition can be stretched at a lower temperature than in the conventional one, and a shrink film obtained by such a low-temperature stretching has a higher shrinkage factor than one stretched at a high temperature, and also has a small natural shrinkage factor.
