  • CLAY-REINFORCED POLY(LACTIC ACID)-POLYOLEFIN ALLOY COMPOSITION
    Publication number: 20120238682
    Abstract: The present invention relates to a clay-reinforced poly(lactic acid)-polyolefin alloy composition comprising 5-50 wt % of a clay-reinforced poly(lactic acid) resin, 40-90 wt % of a polyolefin, and 5-20 wt % of a compatibiliser. A clay-poly(lactic acid) nanocomposite according to the present invention is used with a polyolefin resin to enable the easy distribution of the clay-poly(lactic acid) nanocomposite into microstructure in the polyolefin resin, thereby showing excellent gas and moisture barrier characteristics, so that the composition is suitable for a molded product requiring barrier properties such as a sheet and a film for food packaging, a fuel tank and a portable fuel tank.
