Abstract

A heat-shrinkable polyester film containing a divalent acid component and a diol component, the diol component comprising a diol in an amount ranging from 5 to 95 % by mole, the film having a residual shrinkage stress of 55 kgf/cm² or less after being dipped in 90 °C water for 1 min, and a thermal shrinkage ratio of 40 % or more along the main shrinking direction when treated with 90 °C or 100 °C water for 10 seconds, exhibits high performance characteristics in terms of uniform heat-shrinkage, printing processibility, mechanical strength, heat-resistance, shrinkage rate, and rupture or distortion resistance after secondary thermal shrinkage, e.g., a sterilizing or high temperature-filling process.
