PROBLEM TO BE SOLVED: To obtain a stretched film excellent in heat resistance and toughness which is composed of a polylactic acid composition comprising a PLLA and a PDLA. SOLUTION: The polylactic acid stretched film is composed of the polylactic acid composition comprising 70-30 pts.wt. of the poly-L-lactic acid and 30-70 pts.wt. of the poly-D-lactic acid and has diffraction peaks (2θ) by the wide angle X-ray diffraction around 12°, around 21°and around 24°. Its manufacturing method is also provided. COPYRIGHT: (C)2006,JPO&NCIPI |
