To provide a heat shrinkable film that, when used as a label of beverage container, enhances the smoothness of external surface side to thereby prevent merchandise jamming in an automatic vending machine of beverage and that is fully satisfactory in solvent bonding capability and excels in processability. There is provided a heat shrinkable polyester film characterized in that (A) at least one major surface thereof is overlaid with 0.002 to 0.5 g/m.sup.2, in terms of solid content coating amount of a silicone containing easily slipping layer, (B) a friction coefficient between one and the same easily-slipping layer satisfies a relationship of .mu.d.ltoreq.0.27, and that (C) the heat shrinkable polyester film exhibits a heat shrinkage percentage of not less than 50% in a maximum shrinkage direction, after immersion in hot water at 95.degree. C. for 10 seconds. Thus, there is provided the heat shrinkable film that when used as a label of beverage container, enhances the smoothness of external surface side to thereby prevent merchandise jamming in an automatic vending machine of beverage and that is fully satisfactory in solvent bonding capability and excels in processability.
