Robert J Deffeyes: Package having dessicant composition. Graham Magnetics Incorporated, Robert A Cesari, John F McKenna, Andrew F Kehoe, July 19, 1977: US04036360 (116 worldwide citation)

A package comprising a dessicant material consisting essentially of 1 a dessicant and 2 tough, film-forming, resin having a high moisture vapor transmission rate. A prepolymerized polyurethane is particularly useful. The material is of particular value as a package insert - e.g. with film or cameras ...
