| abstract |
The present invention relates to a polylactic acid resin composition which has optimized flexibility and excellent appearance, and can be effectively used as a packaging film due to the superior physical properties thereof, such as the mechanical properties thereof, transparency, heat resistance, an anti-blocking property, and film processability; and also relates to a packaging film including the polylactic acid resin composition. The polylactic acid resin composition comprises: a hard segment including a predetermined polylactic acid repeating unit; a polylactic acid resin including a polyurethane polyol repeating unit in which polyether polyol repeating units are linearly bound regularly by urethane bonding; and a predetermined amount of anti-oxidant. |
