PROBLEM TO BE SOLVED: To provide a heat-shrinkable film excellent in the resistance against an org. solvent contained in printing ink at the time of application of printing and hard to generate film cutting even if applied to an automatic work machine in film processing work or film mounting work to a commodity. SOLUTION: In a stretched film based on a thermoplastic resin of which the repeating unit is mainly composed of a vinyl aromatic compd., at least one crystallizing peak is present in the measured DSC curve (according to JISK7122; sample amt.: 10 mg; cooling speed: 10 deg.C/min) of the film and the sum total of heats of crystallization is 0.05-5 J/g. |
