Beschreibung
Zusammenfassung:	A method for preparing a polyester-based unstretched sheet, and a polyester-based unstretched sheet prepared by the method are provided to improve the compatibility of an ion complex type antistatic agent and a polyester resin, thereby enhancing antistatic property, heat resistance and chemical and physical properties. A method for preparing a polyester-based unstretched sheet comprises the steps of mixing 40-80 wt% of any one polyester-based resin selected from the group consisting of a polyester resin, a copolyester resin and a polybutylene terephthalate resin, 10-35 wt% of an ion complex type antistatic agent and 10-25 wt% of an ethylene-vinyl acetate copolymer; drying the mixture; and extruding the dried mixture.
