MULTI-LAYERED CONTAINER Russian patent published in 2018 - IPC B65D81/26 

FIELD: packaging industry.

SUBSTANCE: multi-layered container having a layered configuration of 3 or more layers, including an oxygen permeation layer (A), arranged in this sequence from the inner layer to the outer layer, containing the oxygen permeation polymer as its main component, oxygen-absorbing adhesion layer (B) comprising as its main components oxygen-absorbing resin composition (b1) comprising scavenger composition (b1-i) and thermoplastic resin (b1-ii) and adhesive resin (b2), and gas impermeable layer (C) comprising gas impermeable resin as its main component in which the gas impermeable resin is polyamide polymer (X) comprising a diamine unit containing a methoxylylenediamine unit in an amount of 70 mol% or more, and a dicarboxylic acid unit containing from 75 to 96 mole% of a link of an α, ω-unbranched aliphatic dicarboxylic acid containing from 4 to 20 carbon atoms and from 25 to 4 mole% of an aromatic dicarboxylic acid unit, the content of reducing composition (b1-i) in oxygen-absorbent adhesive layer (B) is from 5 to 50 % by weight with respect to 100 % by weight of the material constituting oxygen-absorbing adhesive layer (B), the content of adhesive resin (b2) is 20 to 70% by weight with respect to 100 % by weight of the material constituting oxygen-absorbing adhesive layer (B), and the thickness of oxygen-absorbent adhesive layer (B) is 10 to 30 % of the total thickness of the multi-layered container.

EFFECT: provided a multi-layered container.
