500 GM - 1 KG Blue Silica Gel Bag

About 500 GM - 1 KG Blue Silica Gel Bag

The 500 gm to 1 kg blue silica gel bag is a large-capacity desiccant solution used to safeguard big or sensitive items from moisture damage while in storage or transport. It's packed with blue indicating silica gel beads that have cobalt chloride, a chemical which provides a deep blue color to the beads when they are dry and turns pink when the beads absorb water, giving a definite visual indication of saturation. These bags are constructed of materials that are permeable, such as non-woven cloth, Tyvek, or kraft paper, which permit moisture vapor entry but firmly hold the silica gel. They have a large absorption capacity of up to 3035% of their weight and are widely applied for industrial packaging, electronics, automotive components, machinery, and long-term storage. Although effective, this use of cobalt chloride renders them incapable of being used on food, pharmaceuticals, or other delicate applications.
