Abstract:
To provide a package using a heat-shrinkable polyester film substantially not containing a non-crystalline component, or a packaging container having the same in at least part of an outer periphery of a container.SOLUTION: A package, which is to be cut to fit a packaged object and in which an annular body with both ends of a film bonded together covers at least part of an outer periphery of a packaged object with thermal contraction, comprises, as a base material, a heat-shrinkable polyester film that (1) contains 90 mol% or more of an ethylene terephthalate unit in 100 mol% of a total ester unit, (2) has a melting peak in a temperature-rising process of a differential-scanning calorimeter (DSC), in which a melting point (Tm) that is a peak temperature thereof is 200°C or higher and 280°C or lower and a melting amount of heat (ΔHm) that is a peak area of the same is 40 J/g or greater and 60 J/g or smaller, and (3) in a circumferential direction of the packaged object, a peak of thermal shrinkage percentage appears at 60°C or higher and 120°C or lower, in which a thermal shrinkage percentage at the peak is 1% or greater and 40% or smaller.SELECTED DRAWING: Figure 1
