The present invention not only exhibits improved flexibility, but also has excellent physical properties such as mechanical properties, transparency, heat resistance, blocking resistance, and film processability, and thus may be usefully used as a packaging material. It relates to a packaging film containing. The polylactic acid resin composition includes a hard segment including a predetermined polylactic acid repeating unit, and a soft segment including a polyurethane polyol repeating unit in which certain polyether polyol repeating units are linearly connected through a urethane bond. Polylactic acid resins having an organic carbon content (% C bio ) of mass origin of 60% by weight or more; And a predetermined amount of antioxidant. |
