Abstract
Heat-shrinkable polyester films, each having a heat shrinkability of 5-60% after treatment in hot water at 70° C. for 5 seconds and 65-95% after treatment in hot water at 85° C. for 5 seconds, both in the main shrinkage direction of the film, and 10% or lower after treatment in hot water at 85° C. for 5 seconds in a direction perpendicular to the main shrinkage direction of the film, the heat-shrinkage stress in the main shrinkage direction of the film being 13 MPa or smaller, and the film haze being lower than 10%, exhibits excellent shrinkage finish in appearance with only rare occurrence of wrinkles, shrinkage spots and strains by shrinkage; therefore, these films are suitable for full labels on bottles, particularly for full labels on PET bottles.
