Introduction
Chunwang silica-gel is a high-activity absorbing material in the form of granules or spheres of various sizes.
Its chemical name is Silicon Dioxide (SiO2). It is odorless, tasteless, and non-toxic. Chunwang silica gel desiccant offers an excellent capacity for physical dehumidification because of its good absorbability, chemical stability, wide surface area and high mechanical strength.
Blue silica gel will change color into pink variably according to the quantity of Moisture absorbs, and orange silica gel will change color into green .They are generally mixed together to indicate the Saturation degree of desiccant.
Silica gel desiccant is the most common type of moisture absorbent in the market and it is widely used for various kinds of industries.
What's silica gel?
Silica gel is a high-activity absorbent with the capability of absorbing more than 30% moisture of its weight. And it's the only material that can contact with the food and pharmaceuticals directly by FDA approval.
Why need the silica gel desiccant?
Moisture and oxygen can affect the chemical or physical stability of products, even within packaging materials, products are exposed to moisture and oxygen that can permeate the package from the outside environment. So, the silica gel desiccant is used for absorbing the moisture in the sealed environment to ensure the quality of products and extend their shelf life.
Is it safe for food packaging?
Silica gel is a high-activity absorbent with the capability of absorbing more than 30% moisture of its weight. And it's the only material that can contact with the food and pharmaceuticals directly by FDA approval.
Our food-grade silica gel desiccants are made of excellent type A silica gel beads, packaged with food-grade packaging paper in 100000 class clean room, refined by ultraviolet sterilization.

Q: What's silica gel canister?
Silica gel desiccant canisters are small cylindrical containers filled with white type A silica gel beads that can be inserted at high rates of speed into pharmaceutical bottles and have become the gold standard of pharmaceutical desiccants.
Their special design allows them to be used in standard insertion equipment and continuously fed into pharmaceutical packaging lines. It has become more and more popular in the pharmaceutical packaging industry.
Q: Why use silica gel canister?
A: Moisture and oxygen can affect the chemical or physical stability of many pharmaceutical or nutraceutical products. So, the desiccant canister is used for absorbing the moisture in the sealed environment to ensure the quality of products and extend their shelf life.
Q: How can you ensure the quality.
A: We source the excellent Type A silica gel beads as our raw material, making it has good performance in absorbing moisture. All of our products are under supervised by our QC department, avoiding the inferior products to enter the market.
Q: Is it safe for food or pharmaceutical packaging?
A: Silica gel is the only material that can contact with the food and pharmaceuticals directly by FDA approval.
Besides, our food or pharmaceutical silica gel desiccant are made of excellent type A silica gel beads, produced in 100000 class clean room, refined by ultraviolet sterilization.
Q: Can I customize my own logo? Do you offer OEM service?
A: Of course you can, we'd be very delighted to be your partner.
Q: Can we visit the factory?
