Method for preservation of article

摘要

There is disclosed a method for the preservation of an article by housing an article such as a food, cereal and pharmaceutical in a packaging vessel which is equipped at least in part thereof with an oxygen absorbing resin layer wherein an iron-based deoxidizing agent is kneaded with and dispersed in a theremoplastic resin so that oxygen is absorbed in the layer in the presence of carbon dioxide gas and by hermetically sealing the packaging vessel. It is preferable to house the article in the vessel, subsequently replace the atmosphere in the vessel with carbon dioxide gas, etc. so as to allow carbon dioxide gas to be present therein and thereafter hermetically seal the vessel. The method enables substantially oxygen-free state by the absorption of oxygen in an atmosphere containing carbon dioxide gas and permits the deoxidizing agent packaging through carbon dioxide gas replacement as well as the deoxidizing agent package of an article which generates carbon dioxide gas from itself.
