ABSTRACT:
An oxygen-scavenging system for use in a closure for containers is disclosed. The system is in the form of a closure liner that incorporates a catalyst disposed between an oxygen permeable barrier and a water absorbent backing member. The backing member rests against the inside of the closure and the oxygen permeable barrier rests against the mouth of the container and the catalyst is sandwiched between the backing member and the barrier. The backing member may be porous and the closure may be perforated to allow water to escape.
