<p><P>PROBLEM TO BE SOLVED: To provide a polylactic acid-based film having excellent heat resistance, impact resistance and transparency, and to provide a resin composition. <P>SOLUTION: The polylactic acid-based film and the resin composition have crystallinity regulated so that the film and the resin composition may have anαcrystal of the polylactic acid, and a crystal (α' crystal) of the polylactic acid, having a peak of 2θwithin the range of (a-0.2)°≤2θ≤(a-0.01)°[wherein (a) is the peak of the 2θof theαcrystal by X-ray diffraction], the ratio of crystal intensities of theαcrystal to theα' crystal is from 99/1 to 1/99, and the crystallinity is 3-60%. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
