Barrier film for flexible articles

摘要

This invention relates to an improved gas impermeable barrier membrane having a configuration whereby the membrane is flexible and can retain its barrier performance and integrity when applied to a substrate that is stretched, flexed and or compressed. The inventive membrane is useful for significantly reducing air permeability in inflated articles that are flexible and require a significant amount of stretch to function. The invention is also directed to the construction of such a membrane and its composition.
