Abstract
A polymer composition capable of depleting oxygen from adjacent spaces is disclosed. One or more botanical extracts, either naturally occurring or synthetic, that contain proanthocyanidin or its derivatives are added to a base polymer or polymer blend prior to processing to provide the polymer with oxygen-scavenging benefits without adverse effect to the characteristics of the base polymer or polymer blend.
