Title: Bulk packaging system and method for retarding caking of organic and inorganic chemical compounds

Abstract: 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.
