Where and when to use silica gel packets

The small bags filled with silica gel are the ideal companion for sensitive goods, as they can be added directly to the product packaging. Silica packets protect your goods, from electrical appliances to leather goods, textiles and packaged food, from moisture damage during transport and storage. Since silica gel packets absorb moisture from the air inside the packaging, no condensation water can form inside if used correctly. Mould growth, corrosion, softened cardboard packaging as well as changes in smell and taste are thus prevented.

How does silica gel work as a desiccant?

The silica gel contained in the packets is spherical and has narrow pores. 98% of the glassy beads consist of silicon dioxide. Due to its large inner surface, this silica gel is well suited to adsorb a large amount of moisture. Silica gel is hygroscopic, which means that it can adsorb water molecules. The water remains chemically unchanged and easily dissolves again when the silica gel is regenerated, i.e. dried. Silica gel packets can absorb about one third of their own weight in moisture.

What is a low-dust / dust-proof bag material?

The bag material of Desi Dry low-dust silica gel packets is a composite of paper and non-woven fabric. It is described as low-dust because few dust particles are created by abrasion of the beads, which could then pass through the outer material. In addition, the PE coating between the fleece and the paper ensures stable welding seams.

The bag material of Desi Dry dust-proof silica gel packets is made of a so-called HDPE nonwoven (high-density polyethylene). This non-woven fabric is permeable to water vapor and extremely tear-resistant. The missing fibre ends in the material cause less abrasion, which is why less dust is produced. Thus, it is virtually dust-proof. Tyvek® retains its properties in both wet and dry conditions and is resistant to most acids, bases and salts.

Special feature of Desi Dry Orange silica packets

Desi Dry Orange consists to 90 % of white silica gel and to 10 % of orange silica gel. The orange beads turn green when the water content rises above approx. 6 %. As the desiccant saturation increases, the green colour becomes more intense up to complete saturation. A bluish-green shade indicates complete saturation. The special transparent and tear-proof non-woven bag material allows visual monitoring of the desiccant saturation level. Weighing to check saturation level is therefore unnecessary.
