PROBLEM TO BE SOLVED: To provide a heat-shrinkable film having decreased spontaneous shrinkage and excellent rigidity, strength and chemical resistance. SOLUTION: The heat-shrinkable film is produced by drawing a film of a thermoplastic composition containing >=5 wt.% polymer produced by the cross-copolymerization of an olefin-aromatic vinyl compound-diene copolymer with an olefin-aromatic vinyl compound copolymer (which may contain a diene unit) having an aromatic vinyl compound content different from that of the former copolymer by >=5 mol%. |
