Title:
OXYGEN-ABSORBING PAPER-BASED LAMINATE FOR PAPER CUP CONTAINER
Document Type and Number:
Japanese Patent JP2022014244
Kind Code:
A
Abstract:
To provide an oxygen-absorbing paper-based laminate for a paper cup container with less odor generation, excellent in barrier properties against an oxygen gas and steam, capable of absorbing oxygen to reduce an oxygen concentration in a content housing part of a paper cup container and preventing a content from being deteriorated by oxygen and humidity, while excellent in a balance of heat sealability, low odor property, low oxygen concentration, low humidity, aroma retention and filling packaging property, and also to provide a packaging material and a container.SOLUTION: An oxygen-absorbing paper-based laminate for a paper cup container at least includes a paper substrate layer 3, an oxygen barrier layer 6, an oxygen-absorbing adhesive layer 7 and sealant layers 2a and 2b. The oxygen-absorbing adhesive layer is laminated between the oxygen barrier layer and the sealant layer. The paper substrate layer includes a paper substrate composed of base paper of a specific basis weight. The oxygen barrier layer includes a metal foil and/or a resin film having an inorganic vapor-deposited layer. The oxygen-absorbing adhesive layer at least contains a specific oxygen-absorbing compound and an oxidation accelerator catalyst.SELECTED DRAWING: Figure 1
