ポリ乳酸樹脂フィルムおよびその製造方法
Document Type and Number:
Japanese Patent JP5960725
Kind Code:
B2
Abstract:
The present invention relates to a polylactic acid resin film which has excellent flexibility, mechanical properties, stability, and transparency while having a specific biodegradability of the polylactic acid resin, and is useful as a packaging material. The present invention provides a polylactic acid resin film, comprising a polylactic acid resin including a hard segment comprising a specific polylactic acid repeating unit, and a soft segment comprising a polyurethane polyol repeating unit in which a specific polyether polyol repeating units are linearly linked via a urethane bond, wherein the total Young's modulus in both machine direction and transverse direction of the film is 350 to 750 kgf/mm 2 , and the total initial tensile strength in both machine direction and transverse direction of the film is 20 kgf/mm 2 or more.
