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.
我们公开了一种包装制品,它定义了包装内部和包装外部,并包括:(i) 第一层,包含氧清除聚合物,氧清除聚合物包括 (a) 乙烯骨架或聚酯骨架和 (b) 至少一个环烯烃基;(ii) 第二层,包含功能性阻隔聚合物;以及 (iii) 过渡金属有机盐,位于第一层或与第一层相邻的层中的至少一层;其中第二层位于第一层和包装内部之间。包装物还可以包括功能吸收剂。这种包装物既能清除包装内部的氧气,又能抑制产生异味或臭味的清除副产物从第一层迁移到包装内部。
