摘要: The invention relates to a process for regenerating a polyester container. The process comprises providing the polyester container provided with a polyester film comprising a copolymerized polymer resin comprising a diol component and a dicarboxylic acid component; crushing the container provided with the polyester film to obtain flakes; and thermally treating the flakes at 200°C to 220°C for 60 minutes to 120 minutes to produce regenerated polyester chips. The copolymerized polyester resin comprises neopentyl glycol in an amount of 5 to 35% by mole based on the total number of moles of the diol component. When a plurality of flakes are thermally treated at a temperature of 200°C to 220°C for 60 minutes to 120 minutes, the clumping fraction is 5% or less. The flakes comprise first flakes obtained by crushing the container and second flakes obtained by crushing the polyester film. The heat shrinkable film 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.
