Polylactic acid resin, preparation method thereof, and packing film comprising same |
摘要 |
The present invention relates to a polylactic acid resin and a packaging film comprising the same, wherein the polylactic acid resin is useful as a packaging material due to excellent properties including heat resistance as well as optimized flexibility. The polylactic acid resin comprises: a hard segment including a predetermined polylactic acid repeating unit; and a soft segment including a polyurethane polyol repeating unit in which certain polyether-based polyol repeating units are linearly connected in a medium of a urethane bond. In addition, the polylactic acid resin has a glass transition temperature (Tg) of 25-55℃. |
