Title (EN) POLYLACTIC ACID RESIN FILM
(FR) FILM EN RÉSINE D'ACIDE POLYLACTIQUE
(KO) 폴리유산 수지 필름
Abstract: front page image
(EN)The present invention relates to a polylactic acid resin film which can be used to advantage for packaging and the like, since it exhibits various optimised properties such as outstanding flexibility and mechanical properties while at the same time exhibiting the inherent biodegradability of polylactic acids. The polylactic acid resin film comprises a polylactic acid resin comprising: a hard segment comprising a prescribed polylactic acid repeating unit; and a soft segment comprising a polyurethane polyol repeating unit in which predetermined polyether-based polyol repeating units are linearly coupled by means of urethane bonds, and, in the polylactic acid resin film, the length-direction and width-direction Young's modulus total is between 350 and 750 kgf/mm2, and the length-direction and width-direction initial tensile strength total is at least 20 kgf/mm2.
(FR)La présente invention concerne un film en résine d'acide polylactique qui peut être utilisé avantageusement pour l'emballage et analogue, car il possède diverses propriétés optimisées ‑ telles que souplesse et propriétés mécaniques exceptionnelles ‑ tout en présentant parallèlement la biodégrabilité inhérente aux acides polylactiques. Ledit film en résine d'acide polylactique comprend une résine d'acide polylactique comportant : un segment dur qui comprend une unité récurrente d'acide polylactique prescrite ; et un segment mou qui comprend une unité récurrente de polyol à base de polyuréthane ; les unités récurrentes prédéterminées de polyol à base de polyéther étant reliées de manière linéaire au moyen de liaisons uréthane et, dans le film en résine d'acide polylactique, le module d'élasticité total dans le sens longitudinal et le sens transversal étant compris entre 350 et 750 kgf/mm2, et la contrainte de rupture initiale totale dans le sens longitudinal et le sens transversal étant au moins égale à 20 kgf/mm2.
(KO)본 발명은 폴리유산 수지 특유의 생분해성을 나타내면서도, 우수한 유연성 및 기계적 물성 등 최적화된 제반 물성을 나타냄에 따라, 포장용 등으로 유용하게 사용될 수 있는 폴리유산 수지 필름에 관한 것이다. 상기 폴리유산 수지 필름은 소정의 폴리유산 반복단위를 포함한 하드세그먼트; 및 일정한 폴리에테르계 폴리올 반복단위들이 우레탄 결합을 매개로 선형으로 연결되어 있는 폴리우레탄 폴리올 반복단위를 포함한 소프트세그먼트를 포함한 폴리유산 수지를 포함하고, 길이 방향 및 폭 방향의 영률 합계가 350 내지 750 kgf/㎟이고, 길이 방향 및 폭방향의 초기 인장강도 합계가 20 kgf/㎟ 이상인 것이다.
