Abstract
A packaging system that maintains the free flowing characteristic of solid materials contained therein. The packaging system includes a container, a cover, a vapor permeable bag, a vapor impermeable liner and at least two desiccant snakes. The vapor permeable bag has an opening for receiving solid materials and is formed from cloth or continuous fibers of high-density polyethylene that are randomly distributed and non-directional. The vapor impermeable liner surrounds the vapor permeable bag and provides a moisture barrier. The desiccant snakes are disposed between the vapor permeable bag and the liner. Each snake includes two or more desiccant packages formed from a vapor permeable material through which moisture can freely pass. The desiccant packages contain clay, silica, or molecular sieves.
