PURPOSE:To obtain a heat-shrinkable film capable of being shrunk at low temperatures, free of uneven shrinkage and excellent in uniform shrinkage by adding a specified plasticizer to a polyester resin derived from a dicarboxylic acid component and a diol component. CONSTITUTION:A thermoplastic polyester film obtained from a composition comprising 100 pts.wt. polyester resin derived from a dicarboxylic acid component and a diol component and 1-40 pts.wt. at least one plasticizer selected from among those based on phthalic ester, polyester, aliphatic dibasic acid ester, aliphatic monobasic acid ester, phosphoric ester, citric ester, epoxy compound, trimellitic ester, tetrahydrophthalic ester, glycol and bisphenol A alkylene oxide derivative. |
