Abstract
Oxygen scavenging materials incorporated into or attached to a package such as a gable-top or rectangular carton, used to package foods, beverages or other oxygen sensitive materials, and thereby increase shelf-life by decreasing oxygen in the headspace of the package, and decreasing oxidation of the packaged product.
Claims54
A method of using oxygen scavenging material to decrease oxidation and maintain product properties in packaged beverages, foods, oxygen sensitive materials or oxygen sensitive components comprising the steps of:
- (a) incorporating an oxygen scavenging material into the structure of a container used to package beverages, foods, oxygen sensitive materials or oxygen sensitive components;
- (b) placing beverages, foods, oxygen sensitive materials or oxygen sensitive components in the container;
- (c) scaling the container;
- and
- (d) storing the container at a temperature between 20° F. and 120° F.;
- wherein the oxygen scavenging material is selected from the group consisting of poly(ethylene-methyl acrylate-cyclohexene acrylate)terpolymers, poly(ethylene-vinylcyclohexene)copolymers, and a combination of a polymeric backbone, cyclic olefinic pendent groups and linking groups linking the olefinic pendent groups to the polymeric backbone.
A method of storing beverages, foods, oxygen-sensitive materials or oxygen-sensitive components for an extended period while maintaining product properties comprising the steps of:
- (a) incorporating an oxygen scavenging material into the structure of a container used to package beverages, foods, oxygen-sensitive materials or oxygen-sensitive components;
- (b) placing beverages, foods, oxygen sensitive materials or oxygen sensitive components in the container;
- (c) sealing the container;
- and
- (d) storing the container at a temperature between 20° F. and 120° F.;
- wherein the oxygen scavenging material is selected from the group consisting of poly(ethylene-methyl acrylate-cyclohexene acrylate)terpolymers, poly(ethylene-vinylcyclohexene)copolymers, and a combination of a polymeric backbone, cyclic olefinic pendent groups and linking groups linking the olefinic pendent groups to the polymeric backbone.
