WALL OF PACKAGE, PROCESS FOR MAKING ARTICLE, METHOD FOR PACKAGING OXYGEN SENSITIVE MATERIAL, AND METHOD FOR PRODUCING PACKAGING MATERIAL

摘要

The instant invention concerns an oxygen scavenging material suitable for use in a barrier wall whose oxidative decomposition products comprise one or more aldehydes that are toxicologically innocuous.
The instant invention further concerns a composition comprising a base polymer, at least one compound of the formula E-(L-E) x wherein: E is formula (I) or formula (II) and L is a linking group; and at least one transition metal in a positive oxidation state. The invention also concerns packages containing walls comprising such compositions, methods of forming such packages, and methods of packaging an oxygen-sensitive item within such a package.
