Method for reproducing polyester container and reproduced polyester chips prepared therefrom

A plastic container comprising:

• a polyester container, and
• a heat shrinkable film, which is provided at the polyester container;
• wherein the heat shrinkable film is shrunk by steam or hot air to wrap the outer surface of the polyester container,
• wherein 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,
• wherein 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,
• wherein the flakes comprise first flakes obtained by crushing the container and second flakes obtained by crushing the heat shrinkable film.
