ABSTRACT:
A multi-layer, coextruded blow-molded plastic bottle consists of a layer of EVOH sufficiently thick to inhibit moisture from inside the bottle from penetrating from the interior surface of the EVOH layer to the exterior portion of the EVOH layer, and a second layer positioned exterior to the EVOH layer, wherein the second layer prevents moisture outside the bottle from reaching the EVOH layer, whereby the interior surface of the EVOH layer functions as an oil barrier and the exterior portion of the EVOH layer function as a oxygen barrier.
