Beschreibung
Zusammenfassung:	Disclosed is a multilayer active oxygen barrier film comprising: a) at least one active oxygen barrier layer comprising 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, and b) an iron-based oxygen scavenging composition, 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. The film can be used to wrap or package food products.
