MULTI-LAYERED CONTAINER

摘要

Provided is a multi-layered container including a layered configuration of three or more layers in which layered in the stated order from an inner layer to an outer layer are the following: an oxygen permeation layer (A) comprising an oxygen-permeable resin as a main component; an oxygen-absorbing adhesion layer (B) comprising, as main components, an adhesive resin (b2) and an oxygen-absorbing resin composition (b1) that comprises an oxygen scavenger composition (b1-i) and a thermoplastic resin (b1-ii); and a gas barrier layer (C) comprising a gas barrier resin as a main component. The gas barrier resin is a polyamide resin (X) formed of diamine units comprising 70 mol% or more metaxylylenediamine units and dicarboxylic acid units comprising 75 to 96 mol% C4-20 α,ω-linear aliphatic dicarboxylic acid units and 25 to 4 mol% aromatic dicarboxylic acid units. The content of the oxygen scavenger composition (b1-i) in the oxygen-absorbing adhesion layer (B) is 5 to 50 mass% with respect to 100 mass% of the materials constituting the oxygen-absorbing adhesion layer (B), and the content of the adhesive resin (b2) is 20 to 70 mass% with respect to 100 mass% of the materials constituting the oxygen-absorbing adhesion layer (B). The thickness of the oxygen-absorbing adhesion layer (B) is 10 to 30% of the total thickness of the multi-layer container.
