Title:
POLYESTER HEAT-SHRINKABLE FILM
Document Type and Number:
Japanese Patent JP2023184595
Kind Code:
A
Abstract:
To provide a heat-shrinkable polyester film that exhibits a low value of shrink stress like a polyvinyl chloride resin film.SOLUTION: The polyester heat-shrinkable film can be derived from, e.g., a single amorphous polyester resin, which is a reaction product of a polyvalent carboxylic acid and a polyalcohol, where the polyalcohol used is a mixture of a first polyalcohol having an alicyclic structure and a second polyalcohol having no alicyclic structure. The thermal shrink stress of the polyester heat-shrinkable film measured at 85°C is below 6.8 MPa.SELECTED DRAWING: Figure 1
