Claims17
A thermoplastic resin composition comprising:
- a polylactic acid;
- a thermoplastic polymer having a lower glass transition temperature than the polylactic acid;
- an inorganic nucleating agent;
- and
- at least two reactive plasticizers comprising a modified vegetable oil,
- wherein the thermoplastic resin composition comprises about 70% or more of the polylactic acid based on the total weight of the thermoplastic resin composition,
- wherein the thermoplastic polymer comprises an ethylene vinyl acetate copolymer, which comprises about 60 wt % to about 75 wt % of an ethylene-based structural unit and about 25 wt % to about 40 wt % of a vinyl-acetate based structural unit.
