Abstract
A container closure with a multiple layer liner. The liner comprises a nylon gas transmission barrier and a non-nylon layer bonded by an adhesive layer. The nylon gas transmission barrier may contain an additional passive gas transmission component comprising an in-situ polymerized inorganic clay. An additional active gas transmission component comprising a chemically reactive scavenger may be incorporated into at least one layer of the multiple layer liner. Materials of the liner are selected for their process conditions and resulting resistance to degradation.
