OXYGEN SCAVENGING FILM

摘要

Oxygen scavenging multilayer film, comprising a layer that comprises an oxygen scavenging composition, said layer being separated from a first surface of the film by one or more first layers, characterized in that the oxygen scavenging composition comprises a copolymer comprising substituted polypropylene oxide segments and polymer segments and an oxidation catalyst, wherein the copolymer has been prepared by copolymerising the corresponding monomers of the polymer segments in the presence of functionalised substituted polypropylene oxide segments, wherein the first layers have an overall oxygen permeability of at most 500 cm³ /m². 24h.atm.
