Abstract:
1. A polylactic acid resin composition, comprising a resin composition (l) primarily including a poly-L-lactic acid having an L-form content of 90 to 100 mol % and a resin composition (d) primarily including a poly-D-lactic acid having a D-form content of 90 to 100 mol %, the resin compositions (l) and (d) being stacked alternately one on another with (l) and (d) each being 0.01 to 2.5 μm in a single layer thickness, wherein a peak of a melting point is observed at 210° C. or higher in DSC measurement using a 10 mg sample, and an enthalpy of fusion is measured to be 60 J/g or more when the sample is heated to 280° C., held for 3 minutes, then immediately cooled rapidly, and further subjected to DSC measurement at a temperature raising rate of 20° C. per minute.
