<p>PROBLEM TO BE SOLVED: To provide an oxygen-absorbent multi-layer body and a packaging container which can keep the quality of an object to be preserved over a long period even under use conditions of a high temperature and high humidity, have no problem in irradiation and heating in a microwave oven, and are excellent in impact resistance. SOLUTION: In an oxygen absorbent multi-layer body composed of a heat seal layer of an oxygen permeable thermoplastic resin, an oxygen absorbent layer of a thermoplastic resin in which an iron oxygen absorbent is dispersed, and a gas-barrier layer, an impact resistant intermediate layer of an impact resistant thermoplastic resin is arranged between the oxygen absorbent layer and the gas-barrier layer, and the oxygen absorbent multi-layer body in which the gas-barrier layer is a silica-deposited film is used.</p> |
