发明名称 MOLDINGS COMPRISING A POLYLACTIC ACID COMPOSITION
摘要 An object of the present invention is to provide a polylactic acid composition having specific thermal characteristics and gas barrier properties, and to obtain a molding comprising a polylactic acid composition of PLLA and PDLA capable of forming a polylactic acid stretched film or other molding having superior surface smoothness, transparency, heat resistance and toughness, and the constitution thereof is characterized by being a molding comprising a polylactic acid composition in which the 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, and preferably comprising a polylactic acid composition such that, in measurement during the DSC 2nd heating (cooling at a rate of 10° C./min after allowing to remain at 250° C. for 10 minutes followed by reheating from 0° C. at a rate of 10° C./min), the peak ratio (peak 1/peak 2) of the peak when Tm is 150 to 180° C. (peak 1) to the peak when Tm is 200 to 240° C. (peak 2) is 0.5 or less; and a molding comprising a composition in which an inorganic filler is incorporated in the composition described above.
