How Does Silica Gel Work Through Plastic

Oct 16,2023 | Bond

Silica gel works through plastic by absorbing moisture from the surrounding environment. Silica gel is a desiccant, which means it has the ability to attract and hold water molecules. It consists of tiny silica beads with a high affinity for water.

When silica gel is enclosed in a plastic container or packaging, it can still absorb moisture from the air that permeates through the plastic. The moisture molecules are attracted to the surface of the silica gel beads and become trapped within its porous structure. This process continues until the silica gel reaches its moisture-absorbing capacity.

It is important to note that the effectiveness of silica gel in absorbing moisture through plastic depends on the permeability of the plastic material. Some plastics may allow more moisture to pass through than others. Additionally, the seal or closure of the plastic container plays a role in preventing moisture ingress.

Silica gel packets are commonly used in air-tight sealed containers to protect products from moisture damage. If placed open to the air, they will continuously absorb moisture from the surrounding environment and eventually become saturated 

Remember, when using silica gel or any other moisture-absorbing material, it is important to follow the manufacturer's instructions and guidelines for optimal usage and effectiveness.
