PURPOSE: A polylactic acid-containing polymer alloy composition is provided to ensure high compatibility between polylactic acid-poly propylene resins, to improve melting point for blow molding, and to enable mass production of environment-friendly container. CONSTITUTION: A polylactic acid-containing polymer alloy composition includes (a) 10~60 weight% of polylactic acid, (b) 20~80 weight% of propylene-based resin, (c) 1~20 weight% of reactive compatibilizer, (d) 5~30 weight% of impact reinforcing agent, and (e) 0.1~1.0 weight% of polylactic acid chain extender. The average molecular weight of the polylactic acid is 100,000 ~ 300,000 and the polylactic acid is single or a mixture of two or more selected from poly L-lactic acid, poly D-lactic acid, and poly (D,L)-lactic acid.
