| 摘要 |
The invention aims to provide a polylactic acid based resin sheet that is high in impact resistance, transparency, slipperiness, and creasability, and suitable particularly for production of moldings. This aim is met by a polylactic acid based resin sheet comprising polylactic acid and rubber particles and characterized by meeting requirements 1 to 3 listed below: Requirement 1 "0.01 µm ‰¤ |Ra1 - Ra2| ‰¤ 0.2 µm", requirement 2 "Ra1 ‰¤ 0.3 µ m", and requirement 3 "Ra2 ‰¤ 0.3 µm", where Ra1 is the two-dimensional center line average roughness of one of the faces of the sheet, and Ra2 is the two-dimensional center line average roughness of the surface other than that subjected to measurement of Ra1. |
