  • Multilayer container with barrier protection
    Publication number: 20070160788
    Abstract: A multilayer container having a structural layer of a mixture of a high density polyethylene and a linear low density maleic anhydride modified polyethylene (LLDPE maleic anhydride), preferably in an amount of about 0.01 to about 0.20 percent by weight. The multilayer container has an oxygen barrier layer disposed adjacent the outer structural layer. In a preferred embodiment, the oxygen barrier layer includes EVOH. The LLDPE maleic anhydride facilitates bonding of the structural layer to the oxygen barrier layer.
