[0102] [Oxygen-absorbing multilayer body]

[0103] The oxygen-absorbing multilayer body of this embodiment has an oxygen-absorbing layer (layer A) containing an oxygen-absorbing composition, and a thermoplastic resin layer (layer B) containing a thermoplastic resin (b), the oxygen-absorbing composition containing a transition metal catalyst, a thermoplastic resin (a) and at least one compound having a tetralin ring represented by the following general formula (1),

[0104]

[0105] In general formula (1), R 1 ~R 12 Each independently represents a hydrogen atom or a monovalent substituent, and the monovalent substituent is selected from a halogen atom, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, a heterocyclic group, a cyano group, a hydroxyl group, a carboxyl group, an ester group, an amido group , nitro, alkoxy, aryloxy, acyl, amino, mercapto, alkylthio, arylthio, heterocyclic thio, imide, substituents represented by the following general formula (...

[0281] [Oxygen-absorbing multilayer body]

[0282] The oxygen-absorbing multilayer body of this embodiment has an oxygen-absorbing layer (layer A) containing an oxygen-absorbing composition, and a thermoplastic resin layer (layer B) containing a thermoplastic resin (b), the oxygen-absorbing composition containing A transition metal catalyst, an ethylene-vinyl alcohol copolymer, and at least one compound having a tetralin ring represented by the above general formula (1). For example, it can also be referred to as an oxygen-absorbing multilayer body in which the thermoplastic resin (a) is an ethylene-vinyl alcohol copolymer in the first embodiment.

[0283] The layer structure in the oxygen-absorbing multilayer body of this embodiment is not particularly limited, and the number and types of the oxygen-absorbing layer (layer A) and thermoplastic resin layer (layer B) are not particularly limited. It should be noted that the details of the layer structure are the same as those d...

no. 3 approach

[0317] [Oxygen-absorbing multilayer body]

[0318] The oxygen-absorbing multilayer body of the present embodiment has a sealing layer (layer C) containing a thermoplastic resin, an oxygen-absorbing layer (layer A) containing an oxygen-absorbing composition, and a gas barrier layer containing a gas-barrier substance in this order. (Layer D) at least three layers. In addition, the oxygen-absorbing multilayer body of the present embodiment may further have layers other than these three layers at arbitrary positions as needed. Therefore, the oxygen-absorbing multilayer body of this embodiment can also be said that in the first embodiment, the thermoplastic resin layer is the sealing layer, and the oxygen-absorbing multilayer body includes the sealing layer, the oxygen-absorbing layer, and the gas barrier layer in this order. An oxygen-absorbing multilayer body of at least three layers of the gas barrier layer of the gas-resistant material. Examples of such an oxygen-absorbing mu...

Abstract

The provision of an oxygen-absorbing multilayer body that has the following: an oxygen-absorption layer that contains an oxygen-absorbing composition; and a thermoplastic-resin layer that contains a thermoplastic resin (b). The oxygen-absorbing composition contains at least one tetralin-containing compound that can be represented by general formula (1), a transition-metal catalyst, and a thermoplastic resin (a).

Description

technical field [0001] The present invention relates to an oxygen-absorbing multilayer body, an oxygen-absorbing container, an oxygen-absorbing airtight container, an oxygen-absorbing pharmaceutical packaging (PTP) package, and a preservation method using them. Background technique [0002] In order to prevent oxygen oxidation of various items such as food, beverages, medicines, cosmetics, etc., which are easily deteriorated or deteriorated by the influence of oxygen, and store them for a long time, oxygen absorbers that remove oxygen from the containers containing them are used agent. [0003] As the oxygen absorbing agent, from the viewpoint of oxygen absorbing ability, ease of handling, and safety, an oxygen absorbing agent using iron powder as a reactive main agent is generally used. However, since such an iron-based oxygen absorber is sensitive to a metal detector, it is difficult to use a metal detector for inspection of foreign matter. In addition, the package conta...
