ABSTRACT:
The shelf life of polymeric containers may be economically extended by coating with a barrier material having less than half the permeability of the substrate polymer, the coating being applied to 30 to 75 percent of the container's area, with the proviso that the uncoated area has an average permeability of no more than 15 cc-mm per square meter per day per atmosphere.
