What is Silica Gel?
Silica gel packets are small pouches that are filled with a gel, which is called silica, that absorbs moisture from the area where it is kept. This is an important property of this product, which is why it is commonly used as a drying agent. We can see these small white packets in bags, electronic devices, shoe boxes, water bottles, etc. Though ignored by us, these packets have many interesting uses and properties, which we are going to read about here in this useful article about silica gel.
What are silica gel packets?
This packet contains the naturally occurring mineral silica gel, a porous and granular form of silicon dioxide. Silica gel is commonly used in industrial and commercial applications due to its ability to absorb moisture from the environment. Due to its property as an efficient desiccant, it is mostly used in products that need to be protected from moisture damage.
How do silica gel packets work?
The major function of this packet is to absorb moisture from the surrounding environment. Silica gel is highly absorbent; it can attract water molecules to its surface and then hold them. When it is placed in an enclosed space like shoe boxes, bottles, or bags, it absorbs moisture gradually to its maximum capacity. Once it is saturated with moisture, it will be of no further use and need to be replaced with a new one.
Uses of Silica Gel Packets
- Moisture Absorption
The main work of silica packets is to absorb moisture from the surrounding environment, and therefore we found these packets mostly in the packaging of electronics products, shoes, bags, and many other consumer and industrial products. - Drying flowers and herbs
We can use silica gel packets to dry flowers and herbs for use in crafts and home decorations. Keep the flowers or herbs in a sealed container with silica gel packets; they will absorb the moisture, and we will get dried flowers to be used for our home decor. - Preservation of Documents and Artifacts
We can effectively use these gel packets to preserve and protect our important documents and artifacts from getting damaged by moisture. Libraries and museums often use these packets to protect rare books and manuscripts from moisture and humidity for their long lives. - Preventing silver tarnish
Silica gel packets can also be used to protect precious metals like silver from tarnish. Place these packets in a silverware drawer or jewellery box to prevent the effects of moisture on silver.
Is silica gel safe to use?
Silica gel is non-toxic and non-flammable, and it is safe to use as this chemical does not have a significant risk or effect on human health. We should keep these gel packets away from our pets and kids, as they pose a choking hazard for them.

How much silica gel should we use?
10–20 grammes of silica gel is enough for every 30–50 cm cube of volume in the package for a well-sealed product packaging box.
Can silica gel be reused?
Yes, we can use silica gel several times, and yet it can be effective even if reused. When they absorb water to their maximum capacity, these gel packets can be heated to evaporate the water and are ready to be used again.
Is the Silica Gel Packet safe to use with food items?
Yes, silica gel packets with food-grade labels are safe to be used for storing food items. It helps remove excess moisture and prevents food from getting spoiled.
