METHOD FOR PRODUCING WHITE HEAT-SHRINKABLE POLYESTER FILM, WHITE HEAT-SHRINKABLE POLYESTER FILM, AND PACKAGE

摘要

PROBLEM TO BE SOLVED: To provide a white heat-shrinkable polyester film which is good in perforation opening properties and has light cutting properties, and its production method high in productivity.

SOLUTION: The white heat-shrinkable polyester film contains a polyester resin containing ethylene terephthalate as a main component and at least 15 mol.% of at least one monomer component which can be an amorphous component in all the components of the polyester resin and has a specific thermal shrinkage characteristics, light cutting properties, and specific dynamic characteristics. The production method of the white heat-shrinkable polyester film excellent in productivity is obtained.
