Abstract: The instant invention concerns a composition comprising a base polymer, at least one compound of the formula E-(L-E)x wherein: E is 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.

Abstract: A method of an administrator recording a sale and a retiring of a recycling credit certificate for a recycled material may include the steps of a computing device at the administrator: receiving from a seller a request to generate the recycling credit certificate, transferring the certificate from an account registered by the seller to an account registered by the buyer, receiving from the buyer a request to retire the recycling credit certificate, and recording the certificate as retired. The certificate may include unique information identifying environmental attributes that are unbundled from a corresponding amount of a recycled material. The request to retire the certificate may include an amount of standard manufactured material used in an amount of product bearing a retail product claim for the environmental attributes that were unbundled from the corresponding amount of the recycled material tangibly owned by the seller.

Abstract: The instant invention 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.

Abstract: A method of filling a multilayer container includes providing a multilayer container that is subject to delamination, introducing product contents at an elevated temperature and a liquefied gas, and capping or otherwise sealing the container. The pressure within the container remains positive at temperatures at least as low as ambient, and preferably down to the lower range of household or commercial refrigeration temperatures.

Abstract: A method of filling a container, and thereby extending the effective life of an oxygen scavenger, includes providing a container having an oxygen scavenger material, introducing product contents and a liquefied gas into the container to displace at least a portion of the air within the headspace, and capping or otherwise sealing the container. Displacing oxygen from the headspace diminishes the available oxygen within the container that can permeate into the container sidewall, thereby extending the effective life of the scavenger.
