What’s the fabric used to produce the desiccant bags?

Desiccant salt bags are made from a permeable non-woven fabric, which allows water vapour to be absorbed inside the bag itself. This non-woven fabric, in accordance with DIN 55473, can be divided into two classes depending on the amount of powder that can be released from the desiccant bag itself:

• Class A: Slight dust leakage tolerated (must not release more than 10 mg of dust per desiccant unit);

• Class B: Total dust retention (regardless of the desiccant units, the bag must not release more than 1 mg of dust).

Desiccant bags can also be manufactured with other fabrics approved for food contact, such as Tyvek.
