Patent ID: 8337991

Claim:
A molding, molded by injection-, blow-, or vacuum-/air-pressure molding, or by extrusion, comprising a polylactic acid composition obtained by melt-kneading 75 to 25 weight parts of poly-L-lactic acid and 25 to 75 weight parts of poly-D-lactic acid (the total of poly-L-lactic acid and poly-D-lactic acid being 100 weight parts) so as to obtain a value ranging from 0.3 to 0.6 of the numerical value of the weight-average molecular weight obtained by calculating the weighted mean of the weight-average molecular weights of each of the poly-L-lactic acid and poly-D-lactic acid; and a peak in DSC measurement during cooling (at a rate of 10° C./min) after allowing to remain at 250° C. for 10 minutes is 30 mJ/mg or more.
