Silica Gel Desiccant is a type of physical adsorption desiccant rather than a chemical reaction moisture-absorbing desiccant. Silica gel is an FDA-approved desiccant material that can directly contact food. Compared to other desiccants, silica gel desiccant is relatively better for food moisture protection. In addition to the above factors, silica gel desiccant also has strong moisture absorption capacity and excellent adsorption performance. Even if fully immersed in water, it will not dissolve. It is odorless, non-corrosive, and even if accidentally ingested, it will not be absorbed by the human body. It can be conveniently placed in various product packaging to prevent moisture, rust, mold, and odors. It is suitable for instruments and meters, clothing and footwear, container transportation, home wardrobes, and moisture protection for various items.
