Abstract

A heat shrinkable film and a process for regenerating a polyester container using the same. The heat shrinkable film comprises a copolymerized polyester resin comprising a diol component and a dicarboxylic acid component and has a heat shrinkage rate of 30% or more in the main shrinkage direction upon thermal treatment at a temperature of 80° C. for 10 seconds and a melting point of 190° C. or higher as measured by differential scanning calorimetry. It not only solves the environmental problems by improving the recyclability of the polyester container, but also is capable of enhancing the yield and productivity.
