The invention discloses a polylactic acid-based resin composition composed of a high molecular ingredient (A) comprising polylactic acid (a1) and an aliphatic polyester (B), and a film, particularly an inflation film, prepared from the resin composition. The film comprising the polylactic acid-based resin composition of the invention is biodegradable and excellent in flexibility and resistance to blocking of film and bleeding-out of plasticizer, has no anisotropy in tear strength, and can be suitably used for an agricultural multi-film and garbage bag. When the film of the invention is used for food wrapping, the film prevents fungus growth and contamination of color or odor, and thus can be suitably used.
本发明公开了一种聚乳酸基树脂组合物,由包含聚乳酸(a1)的高分子成分(A)和脂肪族聚酯(B)组成,以及由该树脂组合物制备的薄膜,特别是充气膜。由本发明的聚乳酸基树脂组合物组成的薄膜可生物降解,具有优异的柔韧性、抗堵膜性和抗增塑剂渗出性,撕裂强度无各向异性,可适用于农用多层薄膜和垃圾袋。当本发明的薄膜用于食品包装时,可防止真菌生长和颜色或气味污染,因此可适当使用。
