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. 公开了氧清除性聚合物组合物，其具有改进的氧清除能力并可以形成为透明/半透明薄膜。组合物可以包括分散于聚乙烯中的铁粉、硫酸亚铁七水合物(FeSO4·7H2O)和甘油。这样的组合物可用于制造具有改进的氧清除能力的包装膜。
