Abstract
Embodiments relate to a polyester film, preparation method thereof and method for reproducing polyethyleneterephthalate (PET) container using same, the crystallization temperature (Tc) of the polyester film is not measured or is 70° C. to 130° C., as measured by differential scanning calorimetry, whereby it is possible to easily control the crystallinity. Accordingly, the polyester film has excellent shrinkage characteristics and recyclability, and clumping rarely occurs even if it is dried at high temperatures for a long period of time in the regeneration process.
