PROBLEM TO BE SOLVED: To provide a polylactic acid resin composition high in crystallization temperature, excellent in moldability and heat resistance.SOLUTION: There is provided a polylactic acid resin composition containing polylactic acid of 90 wt.% or more, having crystallization temperatures (peak top temperature:T) at a first and a third temperature decreasing processes each of 155°C or more at measurement of DSC in which a series of steps (1) to (3) of temperature rising, holding and temperature decreasing is repeated three times, and each heat release values (H) of 45 J/g or more. (1) the step of rising temperature from 30°C to 260°C at 20°C/min. (2) the step of holding for 1 minute at 260°C. (3) the step of decreasing temperature from 260°C to 30°C at 20°C/min. |
