Abstract
The embodiments relate to a polyester film, to a process for preparing the same, and to a process for regenerating a polyethylene terephthalate (PET) container using the same. The polyester film has excellent seaming characteristics and recyclability by virtue of controlled crystallinity, whereby clumping rarely occurs even if it is thermally treated for a long period of time in the regeneration process.
