Embodiments relate to a process for regenerating a polyester container and regenerated polyester chips prepared therefrom. The process comprises preparing a polyester container provided with a heat shrinkable film; crushing the container provided with the heat shrinkable film to obtain flakes; and thermally treating the flakes to produce regenerated polyester chips, wherein when the 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, and the flakes comprise first flakes obtained by crushing the container and second flakes obtained by crushing the heat shrinkable film. 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. |
