SILICA GEL SACHETS
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 include Tyvek, fabric, cotton or paper.
Some sachets have heat-sealed seams, others are sewn.
We produce a range of silica gel sachets using non-indicating (white)
or self-indicating (orange/green or orange/colourless) silica gels. In the latter
case, the colours are visible through the sachet fabric or paper.
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 (weights and physical dimensions) are as follows:
0.5 gram (34
1 gram (39 x 20mm)
3 gram (55 x 30mm)
5 gram (50 x 40mm)
10 gram (75 x 40mm)
25 gram (125 x 50mm)
Small non-indicating sachets are made as standard using a
heat-sealed Tyvek material.
This is a very strong dust and lint free material which is ideal for sensitive
A 0.5 gram non-indicating minisachet is also available at 21 x 18 mm.
The self-indicating (0.5, 1, 3 and 5 gram) sachets use a heat-sealed
plain paper made
from a blend of top grade manila hemp, cellulose and thermoplastic fibres.
They vary in size from the non-indicating sachets being, respectively,
40 x 30mm, 50 x 30 mm, 50 x 50 mm and 65 x 50mm.
The 10 and 25 gram self-indicating sachets are made in a heat-sealed non-woven
fabric (see below).
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,
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 very restricted,
consider silica gel in
capsules: 0.3 gram, 0.6
gram and 1 gram.
