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.
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 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.
Large silica gel sachets can prevent moisture damage to items in transit in packing crates, shipping containers, large machinery, and enclosed vessels such as tanks or pipes.
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 using a single large sachet.
The above sachets represent our standard range of off-the-shelf items. In addition, we are able to manufacture sachets to any other weight that meets customer requirements. We can 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 overwrapped in foil or poly pouches. Finally, sachets can be made using a mixture of materials (e.g., silica gel and activated carbon).
We supply sachets in almost any quantity requested. 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 doubling the weight of silica gel does not double the cost. Prices are tiered, with price breaks as quantities increase. Often, dramatic decreases in cost accompany increased quantities. All quoted prices include delivery – no hidden charges.
We can make many different sized sachets using Tyvek™ material – a very strong, dust and lint-free material ideal for sensitive applications.
Usage Tip: 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.
