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. nThe 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. |
