ABSTRACT:
A polymeric container having a permeation retardant laminate welded to a surface of the container. The laminate comprises a polymeric carrier film and a permeation retardant coating applied to the carrier film. The carrier film welds to the container material to form an integral composite structure. The container may be produced by a method wherein a heated polymeric material is extruded within a mold. Laminate is dispensed adjacent hot polymeric material. The hot polymeric material softens the polymeric film carrier causing the two to weld together.
