Abstract: Disclosed are composite polymeric materials in which one or more polymers of the composite are incorporated into a cyclodextrin inclusion complex. Disclosed composite polymeric materials can exhibit improvements in thermal stability as compared to similar materials that do not utilize an inclusion complex in the formulation. In one embodiment, disclosed materials can be quickly composted and biodegraded to form environmentally innocuous components. Additionally, one or more polymers of a material can be derived from renewable resources. Disclosed materials can include additional additives such as nanoclays, inhibitory agents, natural fibers, and so forth and may be formed for use in any of a variety of packaging applications, e.g., injection blow molded packaging materials.

Abstract: An oxygen scavenging system comprising a free radical scavenger (e.g., ?-tocopherol, trimethylhydroquinone, ubiquinol, carotenoids, flavonoids, etc. and mixtures thereof) and a transition metal (e.g., iron (II), copper, manganese, cobalt, etc. and mixtures thereof) in a medium is generally provided. The medium containing the antioxidant and the transition metal has been thermally processed by heating to at least about 150° F. for at least about 10 minutes. Methods of removing oxygen from an environment surrounded by a medium containing the oxygen scavenging system and methods of making the oxygen scavenging system in a medium are also provided.
