a packaging system and method is provided which will substantially retard or reduce the caking of powdered , crystalline , or granular organic and inorganic cakable chemical compounds and mixtures thereof . such retardation and reduction in caking enhances the free flowability and scoopability of the compound . the packaging system and method comprises a moisture impermeable container which may include a moisture impermeable cover which closes the container , providing a moisture tight seal to close the container , and desiccant . the compound can be placed directly into the container or into a moisture permeable bag which is sealed after the compound has been placed therein . the bag is filled or sized so that there will be a void space in the container once the container is closed . the desiccant is placed in the void space . the drum may be a fiber board drum having a moisture impermeable liner , such as an aluminum liner . the cover is preferably a plastic cover . the permeable bag is preferably made of kraft crepe paper or woven polypropylene .
