HEAT-SHRINKABLE POLYESTER-BASED FILM, METHOD FOR PRODUCING THE SAME, AND PACKAGE

摘要

PROBLEM TO BE SOLVED: To provide a heat-shrinkable polyester-based film which can be easily torn along a perforation and which exhibits extremely high productivity.

SOLUTION: The heat-shrinkable polyester-based film comprises ethylene terephthalate as the main constituent and contains ≥15 mole% one or more monomer ingredients capable of forming a non-crystalline component based on the whole polyester-based resin, and has specific heat shrinkage characteristics and specific mechanical characteristics after the heat shrinkage.
