Prevent corrosion damage to delicate or valuable items with Silica Gel Packets
Silica Gel Packets protect goods from moisture during storage and transport by absorbing humidity inside sealed packaging. Made from non-toxic silicone gel in individual sachets, they absorb 22 to 24% of their own weight and remain dry and free-flowing when saturated. This helps prevent leakage onto goods such as cameras, optical equipment, electronics, pharmaceutical packaging, leather goods and footwear. Use 5g of silica gel per cubic foot of sealed air space, with sizes from 1g to 500g available.

Where do silica gel packets work best?
Silica gel desiccant packets protect goods during storage, packing and transit by drawing moisture from sealed air spaces inside boxes, cartons and crates.
- Electronic components and optical equipment, where moisture control helps protect delicate items from corrosion during shipment.
- Cameras and precision goods, where dry packaging helps reduce the risk of humidity-related damage in storage.
- Pharmaceutical packaging, where non-toxic silica gel sachets help maintain a drier pack environment.
- Leather goods and footwear, where packets of silica gel help limit damp conditions inside product boxes and cartons.
Not for
- Open or constantly ventilated areas where the air changes frequently. Use these sachets inside sealed packaging for effective moisture absorption.
- Full container or palletised export loads as the only moisture control method. For freight-level protection, use a calcium chloride desiccant alongside sachets at carton level.
- Spill, leak or liquid water control. These desiccant packets absorb airborne moisture, not free liquids.

Product FAQs
How much silica gel should I use?
Use 5 g of silica gel per cubic foot of sealed air space. Increase the quantity for longer transport routes, humid destinations or packaging that doesn't seal tightly.
Do the sachets leak when full?
No. Each sachet remains dry and free-flowing when saturated, even after absorbing 22 to 24% of its own weight in moisture.
Can these sachets handle high humidity and heat?
Yes. The packets work in high humidity and at temperatures up to 105°C, so they suit long-distance transport by land, sea and air.
Also useful
- Cardboard boxes: for creating a stable outer pack that helps keep the sachet close to the goods being protected.
- Protective packaging: for cushioning moisture-sensitive items before adding silica gel inside the pack.
- Packing tape: for closing cartons securely so the desiccant treats a more controlled air space.
- Pallet wrap: for preparing export loads where carton-level sachets form part of the wider shipping pack.
- Packaging labels: for marking moisture-sensitive cartons clearly during storage and despatch.
