Abstract
The present disclosure relates to a polyester film and a preparation method of the same. Since the polyester film includes a resin layer formed from a polyester resin including a first diol moiety derived from isosorbide and a second diol moiety derived from cyclohexanedimethanol in a controlled ratio on at least one surface of a base layer, it is possible to exhibit excellent heat resistance and adhesion.
