| Zusammenfassung: | The present invention relates to a polyester film for molding which is excellent in moldability and heat resistance. More specifically, the present invention relates to a polyester film for molding which is excellent in moldability and heat resistance during processing by controlling modulus of elasticity, which is an important factor in moldability, by varying the content and thickness of the polymer component in a surface layer and an intermediate layer, wherein the film comprises three layers.
본 발명은 성형성과 내열성이 우수한 성형용 폴리에스테르 필름에 관한 것으로서, 보다 상세하게는, 필름 구성이 3층으로 되어 있고 표면층과 중간층에 폴리머 성분의 함량과 층 두께를 달리하고, 성형성에서 중요한 인자인 탄성율을 제어함으로써 성형성이 우수하고 동시에 가공시의 내열성 또한 우수한 성형용 폴리에스테르 필름에 관한 것이다. |
