PROBLEM TO BE SOLVED: To provide a heat-shrinkable polyester film having excellent shrinking characteristics at low temperatures and excellent shrinking-finish properties, productivity and quality (the amount of pinner bubbles) and suitable for labels. SOLUTION: This heat-shrinkable polyester film comprises >=5 mol% of a 1,4-cyclohexanedimethanol component and >=2 mol% of anα,β-straight-chain alkanediol in 100 mol% of a polyhydric alcohol component in the heat-shrinkable polyester film. The polyester film has >=20% heat shrinkage percentage in the maximum shrinkage direction when dipped in hot water at 85 deg.C for 10 s and <=0.70×10<8>Ω.cm value of melt resistivity at 275 deg.C. |
