摘要

An improved oxygen scavenging system is provided. The system involves an oxygen scavenging phase containing at least one oxygen-scavenger and a second phase comprising at least one catalyst effective in catalyzing a scavenging reaction. The oxygen scavenging phase is substantially devoid of any catalyst of the scavenging reaction and the second phase is effectively separate from the oxygen scavenging phase. Nevertheless, the oxygen scavenging system provides excellent scavenging capabilities while avoiding many of the prior art problems, such as undesired oxidation during high temperature processing when the system is incorporated into a multi-layer film.
