We produce a range of standard size silica gel sachets using non  indicating  , white  or indicating  , orange & green, orange & colorless or blue  silica gels. In the latter case, the colors 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.
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 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.

Stock sachets are as follows :

Sachets made in a heat  sealed non woven 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.

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 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.

All sachet sizes are approximate

Sachets in Tyvek™

We can make many different sized sachets using a TyvekTM material. This is a very strong dust and lint free material which is ideal for sensitive applications.

Which Size Sachet To Use?

A silica gel sachet is always more effective in an enclosed environment. A physical barrier will discourage water vapour from continually entering such an environment, leaving the finite volume enclosed to be protected by the silica gel.

A general rule of thumb in a 'hermetically sealed' environment, is that 5 grams of silica gel are required per cubic foot of enclosed volume  , or 170 grams per cubic meter .
It is often prudent to err on the side of caution and use the nearest standard size sachet over the amount of silica gel that is theoretically required. For large volumes, using a few well spaced smaller sachets will reduce humidity levels faster than if using a single large sachet.

Often, environments cannot be considered 'hermetically sealed', there will be a number of factors which will increase the amount of silica gel that is needed. Please read Using Silica Gel.

Non Standard Sizes And Special Sachets.

The above sachets represent our standard range of off  the  shelf items. In addition to this we are able to manufacture sachets to any other weight that meets customer requirements.
We will also manufacture totally non  standard silica gel sachets    sachets of specific  , and unusual  shape, sachets with loops or lengths of tape attached, sachets with velcro, sachets in bandoliers or sachets that are individually over wrapped in foil or poly pouches. Finally, sachets can be made using a mixture of materials e.g. silica gel and activated carbon.

Pricing & Packing.

We try and sell sachets in almost any quantity that we are asked for. They are supplied in strong cartons with heavy gauge poly bags. If required, packaging can be tailored to suit individual needs In general, non  indicating silica gel sachets are cheaper than self  indicating sachets and to double the weight of silica gel does not double the cost. Prices are tiered, with price breaks as quantities increase. Often dramatic decreases in cost will accompany increased quantities. All quoted prices include delivery, there are no hidden charges.
