Abstract

Disclosed herein is an oxygen scavenging composition for containers. The oxygen scavenging composition for containers may comprise at least one polyester component, a transition metal catalyst, an oxygen scavenger, and a vegetable oil. The vegetable oil preferably comprises at least one molecule having a double allylic structure. The polyester component preferably comprises at least one acid unit and at least one diol unit. The concentration of double allylic structures of the vegetable oil in the composition may be greater than 5.0 meq/kg of all of the polyester components. The oxygen scavenger is preferably present in the composition at a level less than 1.0% by weight of the total composition. The vegetable oil is preferably present in the composition at a level greater than 0.3% by weight relative to the total weight of the polyester components, the transition metal catalyst and the vegetable oil.
