Beschreibung
Zusammenfassung:	An embodiment relates to a polyester-based film which comprises: a polyester resin in which a diol containing 1,4-cyclohexanedimethanol and an aromatic dicarboxylic acid are polymerized; and a filler, wherein tensile strength at room temperature is 15 kgf/mm^2 or more and elongation at break is 60% or more and a preparation method thereof. The polyester-based film can improve tensile strength and elongation at break beyond a specific range so that excellent mechanical properties can be realized. Furthermore, the polyester-based film can improve optical properties and processability such as the winding and running performance of the film. 구현예는 1,4-시클로헥산디메탄올을 포함하는 디올 및 방향족 디카복실산이 중합된 폴리에스테르 수지, 및 필러를 포함하고, 상온에서 인장강도가 15 kgf/mm2 이상이고, 파단 신율이 60 % 이상인 폴리에스테르계 필름 및 이의 제조방법에 관한 것이다. 상기 폴리에스테르계 필름은 인장강도 및 파단신율을 특정 범위 이상으로 향상시킬 수 있어서, 우수한 기계적 물성을 구현할 수 있다. 나아가, 상기 폴리에스테르계 필름은 광학 특성은 물론, 필름의 권취 및 주행 성능 등의 공정성도 함께 향상시킬 수 있다.
