We claim: 1. A method for making a multilayer container, comprising:providing a first masterbatch comprising a chemical desiccant of calcium oxide, a physical desiccant of silica clay and a first polymeric material;providing a second polymeric material;blending the first masterbatch and the second polymeric material to form a subsequent blend, wherein the calcium oxide is present at a range of from about 20 to about 60 weight percent of the subsequent blend;forming the subsequent blend and a third polymeric material into a preform via co-extrusion or via co-injection molding;including a sole desiccant layer between the subsequent blend and the third polymeric material; andblow-molding the preform to form the container, wherein the subsequent blend of the container comprises a thickness of about 20 to 73 mils.
