PROBLEM TO BE SOLVED: To provide a heat-shrinkage polyester-based film which has an appear ance of a frosted glass tone without requiring further working after a film formation, is extremely reduced in occurrence of shrinkage whitening, shrinkage unevenness, wrinkle, distortion, longitudinal sinking or the like and is suitably used for a label. SOLUTION: The heat-shrinkage polyester-based film is characterized by containing 1,4-cyclohexane dimethanol component in an amount of 5% by mol or more in 100% by mol of a polyhydric alcohol component, wherein in the film before the heat-shrinkage, the all-light transmittance is 80 to 90%, the haze is 15 to 60% and the internal haze of the film before the heat-shrinkage measured under the following conditions is 50% or less of the haze. Herein, the internal haze is a haze measured according to JIS K7105 (A method) on a sample obtained by sandwiching the film before the heat-shrinkage, of which upper surface and lower surface are coated with a cedar oil, between two glass plates. |
