Zusammenfassung:	According to an embodiment of the present invention, provided is a polyester film which comprises a film layer including a copolymerized polyester, and a coating layer located on at least one surface of the film layer and includes inorganic particles and flame retardant particles. The flame retardant particles are included in an amount of 1-10 wt% on the basis of the total weight of the coating layer. The polyester film has excellent fouling resistance, formability, and glossless properties, and has flame retardancy. 본 발명의 일 실시예에 따르면, 공중합 폴리에스터를 포함하는 필름층, 및 상기 필름층의 적어도 일면에 위치하며, 무기 입자 및 난연제 입자를 포함하는 코팅층을 포함하는 폴리에스터 필름을 제공한다.
