    摘要： Disclosed is a heat-shrinkable polyester film which, even when stored in an outside warehouse which is not temperature-controlled during a hot summer, does not result in the film shrinking (so-called natural shrinkage); which further has a low decrease in shrinkage rate in the main shrinkage direction, and which can be attached aesthetically and efficiently without changing the temperature conditions for causing heat shrinkage when attaching as a label by heat-shrinking the same to a container (e.g., a plastic bottle). The disclosed heat-shrinkable polyester film comprises a polyester resin having ethylene terephthalate as a main component and containing at least 7 mol % of at least one monomer capable of forming an amorphous component in the whole component of polyester resin. In the heat-shrinkable polyester film, the 80° C.-120° C. glycerin shrinkage, the natural shrinkage rate after high temperature aging, and the number of initial break age after high-temperature aging are adjusted within a specific range.

    摘要： Disclosed is a heat shrinkable polyester film which does not suffer (namely natural shrinkage), is suppressed in decrease of the shrinkage in the main shrinkage direction, and is able to be beautifully and efficiently fitted to a container or the like without changing the temperature conditions for heat shrinkage when the heat shrinkable polyester film is fitted, as a label, to the container or the like by means of heat shrinkage even after high-temperature summer storage in an out door warehouse which has no temperature control system. Specifically disclosed is a heat shrinkable polyester film which is formed from a polyester resin that is mainly composed of ethylene terephthalate and contains 3-12% by mole (inclusive) of one or more monomer components, which can be amorphous components, relative to all the polyester resin components. The heat shrinkable polyester film is characterized in that the shrinkage in 80° C. glycerin, the shrinkage in 130° C. glycerin and the tensile breaking strength in the longitudinal direction are controlled within specific ranges.
