Self indicating silica gel packets are contained in a clear plastic bag. They have many micropores that allow moisture to pass slowly. The indicating silica gel will then indicate the presence of moisture. The self indicating silica gel packet consists of clear silica gel desiccant beads, blue silica gel desiccant beads and orange silica gel desiccant beads.
After the water is absorbed, the blue silica gel desiccant beads gradually change from blue to red. The orange silica gel desiccant beads are orange in the dry state and gradually turn green after absorbing water. Compared with ordinary silica gel desiccants, they can indicate the moisture absorption rate of the desiccant and the relative humidity of the environment.
Self indicating silica gel packets has the advantages of strong absorption capacity, good thermal stability, high mechanical strength, non-toxicity, odorlessness and environmental protection. It is the only desiccant that can be approved by the FDA for contact with food and medicine.
