Abstract:
A method of manufacturing a polyester film, including: preparing a polyester film substrate having an amount of a terminal carboxylic acid group (AV) of from 3 eq/ton to 20 eq/ton, by using a polyester resin having a temperature distribution of a pre-melting peak (Tm′) of from 1° C. to 10° C.; providing a coating layer on at least one surface of the polyester film substrate; and stretching the polyester film substrate provided with the coating layer at least once.
