Silica Gel Packets

Silica gel is a granular form of sodium silicate which has the strong ability to adsorb water vapor molecules. Silica gel packets offer a cost effective way to protect the products against moisture damage during the transportation and storage. Blue indicating silica gel packets contain semi transparent substance known as cobalt. They are available in beads or in crystal structure which are used as an indicator for moisture absorption in various industrial applications. The beads or crystals turn into dark blue color when silica gel releases the moisture whereas light blue color indicates that the beads or crystals have adsorbed the moisture
