Document Type and Number:
Japanese Patent JP7392202
Kind Code:
B2
Abstract:
The present invention relates to a heat-shrinkable polyester film that exhibits a low value of shrink stress like Polyvinyl chloride resin film. Namely, the provided is a polyester heat-shrinkable film obtained from multiple amorphous polyester resins or the like that are reaction products of a polyvalent carboxylic acid and both a first polyalcohol having an alicyclic structure and a second polyalcohol not having an alicyclic structure, wherein the thermal shrink stress at 85° C. is below 6.8 MPa.
