Abstract

A blow molded container having barrier properties and including an upper wall portion having an opening, an intermediate sidewall portion positioned beneath the upper wall portion, and a base portion positioned beneath the intermediate sidewall portion to support the container. The container includes a molded outer layer having an inner surface and an outer surface formed from at least 40% of recycled plastic, and a carbon coating formed on the inner surface of the outer layer and adhered thereto and substantially coextensive with the outer layer, wherein said carbon coating has a thickness of less than about 10 microns. A blow molded multi-layer container is also provided having an upper wall portion, including an opening; an intermediate sidewall portion positioned beneath the upper wall portion; and a base portion positioned beneath the intermediate sidewall portion, the base portion being adapted to dependently or independently support the container. The container includes (i) a molded inner layer formed from a plastic material, the inner layer having a vertical length and a carbon-treated inner surface; and (ii) a molded outer layer formed from recycled plastic that is substantially coextensive with the inner layer.
