Abstract:
A multilayer nonporous oxygen absorbing structure that resists delamination, e.g., humidity induced delamination, including a first layer having a first continuous polymer phase, a first water insoluble, dispersed, polyether resin phase in the first continuous polymer phase, and a water activated oxygen absorber, and a second layer having a second continuous polymer phase, bonded to the first layer.
Abstract:
A composition that absorbs oxygen and emits carbon dioxide in response to absorbing oxygen including ascorbic acid, an organic acid, a catalyst that promotes oxidation of the organic acid and emission of carbon dioxide and a soluble transition metal salt characterized by multiple oxidation states.
Abstract:
A multilayer structure including, in order, a first passive moisture barrier layer, a second passive moisture barrier layer, a first active moisture barrier layer including a first moisture absorbing composition and a cyclic olefin copolymer, and a third passive moisture barrier layer. The first, second and third passive moisture barrier layers and the first active moisture barrier layer are contiguous, non-contiguous or combinations thereof. A method of forming a moisture absorbing multilayer structure including: a) forming a base structure including, in order, a first passive moisture barrier layer, a first active moisture barrier layer and a second passive moisture barrier layer, the first active moisture barrier layer having a first side and a second side opposite the first side and including a cyclic olefin copolymer, the first passive moisture barrier layer disposed on the first side, and the second passive moisture barrier layer disposed on the second side; and, b) coating a third passive moisture barrier layer on the base structure.
