The desiccant method protects against unwanted humidity within packages, preventing moisture-related damage to the packaged goods. In the desiccant method, a desiccant is applied within a closed
atmosphere produced and maintained a microclimate. A waterproof barrier envelope enclosing the packaged goods and desiccant ensures separation from the external climate. The air inside the packaging is dried to such an extent (up to a residual relative humidity of 5%) that no corrosion can occur during transport or storage.
