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™. 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.
The weights include 0.5g,1g,2g,3g,5g,10g,20g,30g,50g,100g,150g etc.
They can also be made according to your request.
