Abstract
The embodiments relate to a polyester film, which 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 170° C. or higher as measured by differential scanning calorimetry, which not only solve the environmental problems by improving the recyclability of the polyester container, but also are capable of enhancing the yield and productivity, and a process for regenerating a polyester container using the same.
