Estimating the term…
Oxygen barrier polyamide compositions exhibiting high oxygen scavenging capability suitable for extended shelf-life, packaging applications. Thus a polyamide composition comprises a polyamide homopolymer, copolymer, or blends thereof, and at least one polyamide reactive, oxidizable polydiene or oxidizable polyether. The polyamide products are particularly suited to making barrier packaging articles such as monolayer or multi-layer films, sheets, thermoformed containers and coinjection/coextrusion blow molded bottles comprising PET, polyolefin or polycarbonate as structural layers. Such articles are useful in a variety of oxygen-sensitive food, beverage, pharmaceutical and health care product packaging applications.
A polyamide composition which comprises a polyamide homopolymer, copolymer, or blends thereof, at least one polyamide reactive, oxidizable polydiene or oxidizable polyether, and an oxidation promoting metal salt catalyst.
A process for producing a polyamide composition which comprises melting a polyamide homopolymer, copolymer, or blends thereof, and blending the molten polyamide homopolymer, copolymer, or blend thereof with at least one polyamide reactive, oxidizable polydiene or oxidizable polyether and an oxidation promoting metal salt catalyst to form a mixture, and then cooling the mixture.
