Abstract
A polylactic acid composition containing polylactic acid and ester-based plasticizer, wherein a content of the ester-based plasticizer is 16 to 33 wt %, and when the composition is highly deformed by stress loading as the relation between the stress and the deformation deviates from linear viscoelastic behavior and thereafter the stress is released, residual deformation measured after the stress is released is not less than 66.0% after 0.2 minute of the stress release, and is not more than 34.0% after 240 hours of the stress release.
