Oxygen scavenging polyamide compositions suitable for pet bottle applications

The invention claims remove oxygen on polyamide composition. With high removing of for preparing a blowing performance, for producing a transparent and anti-delamination performance and multi-layer said PET. The polyamide composition of the invention comprises the sustained-release the polyamide blend, the stabilizing comprising (i) method of aromatic polyamide, wherein copolymer or mixture and (ii) hypocrystalline and aliphatic claims 1-8, copolymer or the mixture, (i) ∶ wherein the weight ratio of about 99∶1 to about 30∶70; At least one of polyamide is oxidable, amino group, a metal salt catalyst at least one of for. Source and PET of said of isolating layer of the invention polyamide composition and product of such as pressure and juice the long shelf-life filler to the oxygen in food.
