HEAT-SHRINKABLE POLYESTER FILM

摘要

PURPOSE:To obtain a heat-shrinkable polyester film having a high shrinkage factor at relatively low temp., almost generating no shrinkage irregularity and excellent in the shrink adhesion to a container such as a bottle. CONSTITUTION:A heat-shrinkable polyester film consists of a dicarboxylic acid component based on aromatic dicarboxylic acid or an ester forming derivative thereof and a diol component and is characterized by that average shrinkage speeds 0-10sec, 10-20sec and 20-30sec after the film is immersed in a hot water bath are respectively within a range of 0.3-3%/sec.
