PROBLEM TO BE SOLVED: To provide a packaging material for desiccants wherein a printed layer is not exposed to the surface, thereby providing good sanitary conditions and the printed layer can be clearly seen from the outside through a moisture- permeable film layer. SOLUTION: An outer layer comprising a moisture-permeable film layer and a printed pattern layer is superposed on an inner layer comprising a first olefin resin layer, a reinforced material layer, and a second olefin resin layer through a partial adhesive layer. The moisture-permeable layer is composed of a nylon, a polyvinyl alcohol, an ethylene-vinyl alcohol copolymer, and a cellophane, while fine pores are formed in the inner layer.
