<p>PROBLEM TO BE SOLVED: To provide a polylactic acid-based resin composition including a polylactic acid resin and a polyethylene resin, which is excellent in the compatibility of both resins and has a steam barrier performance equivalent to that of a polyethylene resin, and to provide a molding composed of the same.SOLUTION: The polylactic acid-based resin composition includes a polylactic acid resin, a polyethylene resin, and an epoxy-modified olefin resin. The composition is characterized in that the difference between melt flow rates of the polylactic acid resin and the polyethylene resin, measured under conditions of a temperature of 190°C and a load of 2.16 kgf, is 20 g/10 min or less, the mass ratio of the polylactic acid resin and the polyethylene resin is 50/50 to 20/80, and the epoxy-modified olefin resin is contained in an amount of 0.5 to 4 pts.mass to 100 pts.mass of the total of the polylactic acid resin and the polyethylene resin.</p> |
