Silica gel sachets or bags, are simply flexible 'containers ' of silica gel. The sachet material has to be robust and capable of withstanding normal handling whilst most importantly, being able to breathe. This means that water molecules can pass through the material and be adsorbed by the silica gel. Standard sachet materials are tea-bag paper, fabric, cotton or Tyvek™. Some sachets have heat-sealed seams, others are sewn.
We produce a range of standard size silica gel sachets using non-indicating (white) or self-indicating (orange/green, orange/colourless or blue) silica gels. In the latter case, the colours of the gels are visible through the sachet paper or fabric. Self-indicating silica gel sachets are often useful in test situations, to confirm the suitability of the sachet size chosen, or in cases where an item is frequently inspected and the sachet can be replaced if it has become exhausted. Stock sachets are as follows :
Sachets made in a heat-sealed teabag paper.
Non-Indicating And Self-Indicating.
Small sachets are manufactured as standard in a plain paper made from a blend of top grade manila hemp, cellulose and thermoplastic fibres. All sachets are printed Silica Gel Do Not Eat.

Small silica gel sachets can prevent moisture damage to electrical goods and electronic components (internally and externally), scientific and optical instruments, communication equipment, metallic parts, leather goods, tools and many other small to medium sized items in use, store or transit.
For situations where the physical space for a sachet is restricted, consider capsilgels. Stock sizes for capsilgels are 0.3 gram, 0.6 gram and 1 gram.
Sachets made in a heat-sealed non-woven fabric. Non-Indicating and Self-Indicating.
Medium sized sachets are manufactured as standard in a heat-sealed non-woven fabric made from a 100% viscose fibre with an acrylic binder and polyamide coating. All sachets are printed Silica Gel Do Not Eat and usually with their weight.
Medium sized silica gel sachets can prevent moisture damage to larger electrical/electronic items, metallic components and fabrications, contents of export packing cartons or crates and hygroscopic powders.
Sachets made in a stitched non-woven fabric or cotton. Non-Indicating and Self-Indicating .
The 1kg sachet is stitched in a non-woven fabric made from a 100% viscose fibre with an acrylic binder. The 2.5 kg sachet is made as standard in cotton because of its large weight. All sachets are printed Silica Gel Do Not Eat along with their weight.
Large silica gel sachets can prevent moisture damage to items in transit in packing crates and shipping containers, large machinery and enclosed vessels such as tanks or pipes.
The aim of using silica gel sachets is to minimise the risk of irreversible damage to items in transit or store caused by condensing water vapour. By adsorbing water molecules, a silica gel sachet will reduce the Relative Humidity inside a package to levels at which condensation will not occur .
Three main moisture sources need to be considered :
(1) That from the air contained in the package.
(2) That from the packing added inside of the package (e.g. for cushioning purposes).
(3) That which diffuses through the outer packaging during storage or transit.
