PROBLEM TO BE SOLVED: To provide a polylactic acid film showing excellence in prevention of plasticizer bleeding to one surface of a film, prevention of blocking between film themselves and tackiness of the other side of the film, and having good flexibility and transparency. SOLUTION: The polylactic acid film has the outermost layer (A) and the outermost layer (B). The outermost layer (A) contains a polylactic acid-based resin (a), the plasticizer and a nucleating agent. The polylactic acid-based resin (a) comprises 45 to 85 mass% of the poly DL-lactic acid (1) having a D-ratio of 7 to 20% and 15 to 55 mass% of a poly DL-lactic acid (2) having a D-ratio of not less than 0 to less than 7% or a poly L-lactic acid having a D-ratio of 0%. The outermost layer (B) contains a polylactic acid (b) and a plasticizer. The polylactic acid (b) comprises 70 to 100 mass% of the poly DL-lactic acid (1) and 0 to 30 mass% of the poly DL-lactic acid (2) or the poly L-lactic acid. COPYRIGHT: (C)2010,JPO&INPIT |
