The presence of strings makes positioning these dehydrating bags simple. You can tie them directly to machinery or furniture before packing them for shipping, or use them in special packaging, containers and small spaces.

These sachets contain clay, a completely natural desiccant that is economical and highly effective in its absorbent power, making it advantageous over other options.

How much can clay absorb?

Bentonite is a particular clay of natural origin, whose absorption capacity may vary from one batch to another. For this reason, when talking about bentonite it is correct to report its actual absorption capacity and not the weight or the actual dimensions of the sachet, since these are irrelevant and do not demonstrate the drying capabilities of the product.

This is the reason why between one batch and another the weight of each individual sachet of bentonite can vary by +/-17%, but the absorption capacity is precisely defined.

The absorption capacity for this product is 2U according to NFH system.

(*)  The absorption capacity refers to standard conditions of 40% relative humidity with a temperature of 23° C.

This drying material may release a fine dust. Although the maximum permitted quantity of dust that can escape from the casing is 10 mg/u.d., in accordance with the DIN 55473 standard, we do not recommend the use of bentonite sachets with optical equipment such as cameras, lenses, binoculars, etc. as the fine dust, even if in minimal quantities, could create abrasions on the surface of the lenses.



The bentonite sachets arrive sealed in heat-sealed plastic bags directly from the factory, in order to protect them from any contact with humid environments during transport or storage, thus avoiding providing the customer with a product that has already absorbed a percentage of humidity.

Immediate shipping for all orders placed before 12.00/working days.
