Abstract
Oxygen scavenging polymeric compositions that possess an improved oxygen scavenging capability and can be formed into transparent/translucent thin films are disclosed. A composition can include iron powder, ferrous sulfate heptahydrate (FeSO4.7H2O) and glycerol dispersed in polyethylene. Such compositions are useful for creating packaging films with improved oxygen scavenging capability.
