Beschreibung
Zusammenfassung:	Disclosed is a multilayer active oxygen barrier film comprising a multilayer oxygen barrier component comprising at least one of i) an active oxygen barrier layer that is disposed between two opposing passive oxygen barrier layers, or ii) a passive oxygen barrier layer that is disposed between two opposing active oxygen barrier layers, wherein the active oxygen barrier layer comprises an oxygen scavenging composition that is a blend of: (A) a thermoplastic resin having carbon-carbon double bonds substantially in its main chain; (B) a transition metal salt; and (C) an oxygen barrier polymer selected from the group consisting of ethylene-vinyl alcohol copolymer (EVOH), polyvinyl alcohol, polyvinyl chloride, polyacrylonitrile, and combinations thereof, wherein the passive oxygen barrier layer is selected from the group consisting of ethylene vinyl alcohol, polyvinyl alcohol, and copolymers and combination thereof, and wherein the multilayer oxygen barrier component is disposed between an outer sealant layer and an outer abuse layer, and wherein the film has an oxygen scavenging rate that is at least about 0.01 cc oxygen per day per gram of the oxygen scavenging composition blend.
