"POLYAMIDE COMPOSITION, OXYGEN BARRIER FILM, MULTI LAYER ARTICLE AND FILM, MOLDED ARTICLE, PROCESS FOR PRODUCING A POLYAMIDE COMPOSITION, PROCESS TO PRODUCE A POLYAMIDE FILM FOR OXYGENIDE BARRIER PRODUCTS " Packaging applications of polyamide compositions for use as an oxygen barrier, which exhibit high oxygen sequestration capability suitable for prolonged storage. Thus a polyamide composition comprises a homopolymer, or a copolymer of polyamide or mixtures thereof and at least one reactive polyamide, an oxidizable polydiene or an oxidizable polyether. Polyamide products are particularly suitable for manufacturing oxygen barrier packaging such as single layer or multilayer films; thermally formed blades, containers and vials formed by co-injection and blow co-extrusion comprising PET, polyolefins or polycarbonates as structural layers. Such articles are useful for a variety of oxygen sensitive food packaging, soft drink, pharmaceutical and health care applications.
