본 발명은 생분해성 폴리에스테르를 개시하고, 그중, 생분해성 폴리에스테르 조성물의 총 중량을 기준으로, 테트라히드로푸란의 중량함유량을 3ppm-200ppm로 하고, 생분해성 폴리에스테르 조성물의 총 중량을 기준으로, 시클로펜탄온의 중량함유량을 0.5ppm-85ppm로한다. 본 발명은 조성물중에 테트라히드로푸란과 시클로펜탄온을 첨가하고, 조성물중의 테트라히드로푸란과 시클로펜탄온의 함유량을 일정한 범위내에 컨트롤함으로 인해, 생분해성 폴리에스테르 조성물의 인쇄과정중 인쇄불량 현상을 현저히 개선시키고, 잉크가 박막자재로부터 이탈하는 현상이 나타나지 않을 뿐만 아니라, 잉크가 너무 많아 박막자재에 부착되는 현상이 발생하지 않으므로, 박막이 뛰어난 인쇄성능을 가지게 하며, 생분해성 폴리에스테르의 취입성형중 윤활성을 개선 시킬 수 있으며, 취입성형속도가 176 Kg/h일 경우, 박막두께 극차가 <0.2μm, 막 두께의 상대편차가<1%로서, 취입막의 안정성과 취입성형의 연속성을 보증할 수 있다. The present invention discloses a biodegradable polyester, wherein the weight content of tetrahydrofuran is 3ppm-200ppm based on the total weight of the biodegradable polyester composition, based on the total weight of the biodegradable polyester composition, The weight content of cyclopentanone is 0.5 ppm to 85 ppm. The present invention adds tetrahydrofuran and cyclopentanone to the composition and controls the content of tetrahydrofuran and cyclopentanone in the composition within a certain range, thereby significantly reducing the printing defects during the printing process of the biodegradable polyester composition. In addition, the ink does not appear to be separated from the thin film material, and the ink does not appear to adhere to the thin film material because the ink is too large, so that the thin film has excellent printing performance and lubricity during the blow molding of the biodegradable polyester. When the blow molding speed is 176 Kg / h, the film thickness difference is <0.2 μm and the relative deviation of the film thickness is <1%, which ensures the stability of the blown film and the continuity of the blow molding.
