PROBLEM TO BE SOLVED: To obtain a shrinkable film having excellent drawing processability and slipping property, etc., without losing characteristics such as transparency, surface gloss and heat resistance, and useful for heat-shrinking package by using a drawn film containing a specific crystalline polypropylene as a main component. SOLUTION: This shrinkable film is composed of a drawn film comprising crystalline polypropylene wherein a peak temperature of an eluting curve measured by temperature-rising eluting fractionation method using o-dichlorobenzene as a solvent is 90-110 deg.C and an eluting integrated weight fraction is 0-10wt.% below <=20 deg.C, 60-80wt.% at a temperature range within 20-100 deg.C and 10-40wt.% at a temperature range within 100-130 deg.C, as a main component. A laminated film is obtained by laminating the drawn film on at least one surface of a base layer comprising a polyolefin-based drawn film having 15% areal shrinkage at 90 deg.C. |
