    摘要: Oxygen barrier films exhibiting high oxygen scavenging capability suitable for extended shelf-life, packaging applications. These films comprise a polyamide homopolymer, copolymer, or blends thereof; an ethylene vinyl alcohol copolymer; an oxidizable polydiene; and at least one metal salt catalyst. These films are particularly suited to making high barrier, retortable packaging structures such as pouches, containers etc. Such articles are useful for packaging a variety of oxygen-sensitive foods, beverage, medical and health care products.

    摘要: Oxygen barrier polymer compositions exhibiting high oxygen scavenging capability suitable for extended shelf-life, packaging applications. These polymer compositions comprise at least one ethylene vinyl alcohol copolymer, at least one oxidizable polydiene, and at least one metal salt catalyst. The polymer products are particularly suited to making barrier packaging articles such as monolayer or multi-layer films, sheets, tubes, pipes, 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.
