    摘要： 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.
