Abstract

A multilayer container having a layer configuration of 3 or more layers including, as layered in that order from an inner layer to an outer layer, an oxygen-permeable layer containing an oxygen-permeable resin as the main component thereof, an oxygen-absorbing adhesive layer containing, as the main components thereof, an oxygen-absorbing resin composition containing a deoxidant composition and a thermoplastic resin and an adhesive resin, and a gas-barrier layer containing a gas-barrier resin as the main component thereof, wherein the gas-barrier resin is a polyamide resin including a diamine unit containing a metaxylylenediamine unit in an amount of 70 mol % or more and a dicarboxylic acid unit containing 75 to 96 mol % of an α,ω-linear aliphatic dicarboxylic acid unit having 4 to 20 carbon atoms and 25 to 4 mol % of an aromatic dicarboxylic acid unit, the content of the deoxidant composition in the oxygen-absorbing adhesive layer is 5 to 50% by mass relative to 100% by mass of the material constituting the oxygen-absorbing adhesive layer, the content of the adhesive resin is 20 to 70% by mass relative to 100% by mass of the material constituting the oxygen-absorbing adhesive layer, and the thickness of the oxygen-absorbing adhesive layer is 10 to 30% of the total thickness of the multilayer container.
