HEAT-SHRINKABLE POLYESTER-BASED FILM

摘要

PROBLEM TO BE SOLVED: To provide a heat-shrinkable polyester-based film suitable for full- labeling of large-sized plastic bottles, to which hardly occur wrinkles, shrinkage unevenness and strain due heat shrinkage. SOLUTION: This heat-shrinkable polyester-based film is made from a polyester resin and characterized by being >50% in hot water shrinkage in the main shrinkage direction at a treatment temperature of 70 deg.C for a treatment time of 5 s and >=75% at 80 deg.C for 5 s and <=1.45%/ deg.C in the average rate of change in the hot water shrinkage at 70-80 deg.C.
