Abstract
A method for manufacturing of a plastic container which is substantially impervious to oxygen by providing a bottom film oxygen barrier, the film oxygen barrier having an area greater than the area of a floor of the plastic container; providing a side oxygen barrier film, the side oxygen barrier film being dimensioned to circumscribe a sidewall of the plastic container and having a length greater than the length of the plastic container. A mold has a floor and a sidewall, the mold having a groove extending below the floor and dimensioned to receive an excess length of the side oxygen barrier film therein, and the bottom oxygen barrier film being dimensioned to extend at least partially across said groove. The film oxygen barriers are placed within the mold and a plastic container is injection molded within the cavity.An oxygen resistant container has a floor. A sidewall extends from the floor. An oxygen barrier material is disposed on the floor and sidewall. The oxygen barrier material is one of a nano-silicate and a nano-clay.
