Abstract
The present invention generally related to a monolithic composition comprising a water insoluble polymer and a deliquescent material. A deliquescent material is blended into the polymer so that the deliquescent material is distributed within the product. The deliquescent material blended in the water-insoluble polymer is capable of maintaining a substantially constant relative humidity in a closed container. The product may be used to form a desired shaped article such as plug type inserts and liners for closed containers, or it may be formed into a film, sheet, bead or pellet.
