Article and method for retarding the deterioration rate of acidic paper

Abstract

A method for retarding the deterioration rate of acidic paper is disclosed. The method includes placing an acidic paper article in a polymer film enclosure having a reservoir of deacidifying agent. The deacidifying agent migrates over time to the paper article in an amount sufficient to retard the deterioration rate of the paper. The method can further include placing in the polymer film enclosure a carrier material having a second reservoir of deacidifying agent. An article for retarding the deterioration rate of acidic paper is also disclosed. The article includes a polymer film enclosure having a reservoir of deacidifying agent. The polymer film enclosure is capable of enclosing an acidic paper article. The deacidifying agent is capable of migrating over time to the acidic paper article enclosed therein in an amount sufficient to retard the deterioration rate of the paper. The article can further include a carrier material having a reservoir of deacidifying agent.
