Bentonite desiccants – The natural, sustainable desiccant solution for moisture controlled packaging
Desiccants are hygroscopic (moisture-adsorbent) substances that are packaged and used to protect a wide range of products from mold, corrosion, and other forms of moisture-related degradation and damage. Desiccants are critical to maintaining product quality and shelf life. Two of the most widely used and well-known desiccants are bentonite clay and silica gel, which are used to protect products ranging from textiles, leather goods, electronics, metal components, and foods to pharmaceuticals,nutraceuticals, and medical devices.
Bentonite clay is an abundant and naturally-occurring mineral that results from the weathering and sedimentation of volcanic ash deposits. Its principal ingredient is calcium montmorillonite, a highly adsorbent, chemically inert and non-corrosive substance. When mined from the ground, then processed and dried into the form of free-flowing granules, bentonite clay attracts and binds water vapor readily within its complex and highly layered structure, making it a highly effective desiccant.
