Desiccants are substances or materials used to absorb moisture from the air, reducing humidity levels in their immediate environment. They come in various forms, including silica gel packets, clay desiccants, molecular sieves, and activated carbon. Desiccants are commonly used in packaging to protect sensitive products from moisture damage during storage and transportation. By absorbing excess moisture, desiccants help prevent corrosion, mold growth, and degradation of goods, preserving their quality and integrity. Desiccants are widely used across industries such as pharmaceuticals, electronics, food packaging, and textiles to maintain product freshness and stability.
