摘要： The embodiments relate to a polyester film and a process for regenerating a polyester container using the same, which not only solve the environmental problems by improving the recyclability of polyester containers, but also are capable of enhancing the yield and productivity. The polyester film comprises a first layer comprising a first resin comprising a diol component and a dicarboxylic acid component; and a second layer laminated on one side of the first layer and comprising a second resin different from the first resin, wherein when the polyester film is cut with a polyethylene terephthalate container to form flakes and the flakes are thermally treated at a temperature of 200° C. to 220° C. for 60 minutes to 120 minutes, the clumping fraction is 8% or less.
