Oxygen scavenging packaging having improved sensory properties |
摘要 |
We disclose a packaging article, defining a package interior and a package exterior, and comprising (i) a first layer, containing an oxygen scavenging polymer the oxygen scavenging polymer comprises (a) an ethylenic backbone or a polyester backbone and (b) at least one cyclic olefinic group; (ii) a second layer, containing a functional barrier polymer; and (iii) a transition metal organic salt in at least one of the first layer or a layer adjacent to the first layer; wherein the second layer is located between the first layer and the package interior. The packaging article can further comprise a functional absorber. Such a packaging article is capable of both scavenging oxygen present in the package interior and inhibiting the migration of off-taste- or off-odor-imparting scavenging byproducts from the first layer to the package interior.
