To provide a plastic multi-layer container for an oxidizing hair dye which has outstanding aroma retaining properties and ensures an effective inhibitive effect upon the deterioration of interlayer adhesion, even in case the container is filled with the oxidizing hair dye containing a specific component.
This plastic multi-layer container is filled with the oxidizing hair dye containing at least a higher alcohol and/or a surfactant and constituted of an inner layer formed of a linear olefinic resin, a first intermediate layer formed of a cyclic olefinic copolymer, a second intermediate layer formed of an ethylene-vinyl alcohol copolymer and an outer layer formed of a linear olefinic resin, laminated over each other through an adhesive resin layer formed between the layers. In addition, the adhesive resin is composed mainly of an acid modified product of a polyethylene or an ethylene/α-olefin copolymer obtained by copolymerizing ethylene with 4 to 20 mol% of the α-olefin per resin. The density of the adhesive resin is 0.880 g/cm3 to 0.940 g/cm3.
