A desiccant is a hygroscopic substance that absorbs or adsorbs water. It is most commonly used to remove humidity that would normally degrade or even destroy products sensitive to moisture. Silica gel, calcium sulfate, montmorillonite clay and molecular sieves are commonly used as desiccants. The desiccant bags are used in packaging of any materials to protect it from any deformation. The capacity of the bagged desiccant was substantially greater than the other desiccant types like desiccant-coated paper due to the larger size of silica gel crystals.
