Abstract
The present invention relates to a polylactic acid resin composition having eco-friendly properties, which can be effectively used as a packaging material due to improved flexibility and moisture resistance, as well as superior general properties such as mechanical properties, transparency, heat resistance, an anti-blocking property, and film processability. The inventive polylactic acid resin composition comprises a polylactic acid resin comprising a hard segment comprising a polylactic acid repeating unit and a soft segment comprising a polyolefin-based polyol repeating unit in which polyolefin-based polyol structural units are linked in a linear or branched manner via a urethane bond or an ester bond, wherein the organic carbon content (% C) of biomass-based carbon, as defined in Equation 1, is at least 60 wt %; and an antioxidant.
