Title:
OXYGEN-ABSORBING COATED MULTILAYER BODY
Document Type and Number:
WIPO Patent Application WO/2023/132021
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a multilayer body which generates less odor, while having excellent barrier properties with respect to an oxygen gas, and which suppresses deterioration of the content in a package due to oxygen by absorbing the oxygen in the space within the package, while achieving an excellent balance between oxygen absorption performance and low odor generation; the multilayer body, which is reduced in the load on the environment by containing a plant-derived resin; and a packaging material and a package, each of which is produced using the multilayer body. The present invention provides: an oxygen-absorbing multilayer body comprising a layered configuration which is obtained by sequentially stacking at least an oxygen barrier layer, an oxygen-absorbing adhesive layer and a sealant layer in this order, wherein the oxygen-absorbing adhesive layer is formed from an oxygen-absorbing adhesive composition that contains at least a specific oxygen-absorbing compound and an oxidation promoting catalyst; and an oxygen-absorbing coated multilayer body which comprises at least a base material layer, an oxygen barrier layer and an oxygen-absorbing coat layer, wherein the oxygen-absorbing coat layer is formed from a specific oxygen-absorbing coating agent composition.
