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 a shrinkage factor in one direction (shrinking direction) at the time of heating in a hot water bath for 60 sec is 20% or more at 60 deg.C and shrinkage start temp. is 50 deg.C or lower.
