Abstract

A multilayered container includes at least a polyolefin inner layer; an adhesive layer; a gas-barrier layer; an oxygen-absorbing layer; a gas-barrier layer; an adhesive layer; a polyolefin outer layer, and having at least a body portion and a bottom portion, wherein the gas-barrier layers include an ethylene-vinyl alcohol copolymer, the oxygen-absorbing layer includes an oxygen-absorbing resin composition that contains the ethylene-vinyl alcohol copolymer and an oxidizing organic component, an adsorbing agent is contained on the side inside of said gas-barrier layer, the thickness of the multilayered container at the thinnest portion is not more than 430 μm, and the amount of oxygen absorbed after the heat-sterilization is not less than 23 cc per gram of the oxygen-absorbing resin composition. Despite of this decreased thickness, the multilayered container maintains excellent oxygen-barrier property and property for retaining flavor of the content even when it is subjected to the retort sterilization.
