Title:
PACKAGE AND PACKAGING CONTAINER
Document Type and Number:
Japanese Patent JP2019177930
Kind Code:
A
Abstract:
To provide a package that does not substantially contain an amorphous component and has a high heat shrinkage rate in a width direction, and use a heat-shrinkable polyester film with a small thickness spot, or a packaging container having the package on at least a part of an outer periphery of the container.SOLUTION: A package meets the following requirements. (1) A heat-shrinkable polyester film contains 90 mol% or more of ethylene terephthalate units in 100 mol% of all ester units. (2) the heat-shrinkable polyester film has a melting peak in the temperature rising process of a differential scanning calorimeter (DSC), a melting point (Tm) of 200°C or higher and 280°C or lower, and a heat of fusion (ΔHm) of 40 J/g or more and 60 J/g or less. (3) In a circumferential direction of the packaging object, a peak of heat shrinkage of the heat-shrinkable polyester film obtained by thermomechanical analysis (TMA) appears at 60°C or more and 120°C or less, and the heat shrinkage rate at the peak is 1% to 40%.SELECTED DRAWING: Figure 1
