Purchasing silica gel sachets and when to use them

We stock silica gel packets that are ideal for use with sensitive goods, as they can be added directly to the product packaging. Silica gel packets protect many kinds of goods – from electrical appliances to leather goods, textiles and packaged food – from moisture damage during transport and storage. Since silica gel sachets absorb moisture from the air inside the packaging, no condensation water can form inside if used correctly. This prevents mould growth, corrosion, softened cardboard packaging, as well as changes in smell and taste.

How do silica gel packets control moisture?

Our silica gel beads are spherical with narrow pores – 98 per cent of the 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. Adsorbed 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 does ‘low-dust’ and ‘dust-proof’ mean when referring to the bag material that silica gel comes in.

The bag material used for Desi Dry low-dust silica gel packets is a composite of paper and non-woven fabric. The product is described as low-dust because the silica gel beads produce very few dust particles and the bag material also works to reduce the amount of dust that passes through it.. In addition, the PE coating between the fleece and the paper ensures stable welding seams.

The bag material used for Desi Dry dust-proof silica gel packets is made of what’s known as HDPE (high-density polyethylene) Nonwoven . This non-woven fabric is permeable to water vapour and extremely tear-resistant. The lack of any fibre ends in the material causes less abrasion, producing a minimal amount of dust – hence it being labelled ‘dust-proof’.

Self-indicating Desi Dry Orange silica sachets

Desi Dry Orange silica packs consist of 90 per cent white silica gel and ten per cent orange silica gel. The orange beads turn green when the water content rises above around six per cent. As the desiccant becomes more saturated, the green colour becomes more intense – with a bluish-green shade indicating complete saturation. The transparent and tear-proof non-woven bag material allows visual monitoring of the desiccant saturation level – making weighing to check saturation level unnecessary.
