Desiccant bags are produced with a permeable non-woven fabric allowing absorption of water vapour within the bag. In conformity with DIN 55473 non-woven fabric differ in terms of properties of dust permeability: - Type A dust proof (max. dust release = ≤10 mg/u.d)- Type B dust free (max. dust release = ≤1 mg/bag)
Traditional desiccant bags are used inside packages of various sizes and serve to protect the product from the moisture that forms inside them. Container desiccants are obviously used inside
