How Do Desiccant Bags Work?
For a desiccant bag to function optimally it must be placed in an airtight system which does not allow air to circulate into the product. An airtight system is usually created using aluminum foil/barrier foil, within which the product is stored or transported. Desiccant bags are used to absorb moisture in order to achieve a moisture level optimal for the product during storage or transit. A standard performance definition is the desiccant unit. One unit of desiccant is defined as having an adsorption capacity of 6 grams of water at 77° F (25°C) and 40% RH.
Moisture is often harmful and can lead to rusting, corrosion, and damage to your product. A desiccant bag absorbs the moisture and binds it within the desiccant bag itself. Desiccant bags are made in such a way that moisture can enter but not escape. Desiccant bags are available in many sizes, so you will always find one to suit your purposes. Available for small and medium-sized consignments, containers and very large consignments.
Desi-Pak Tyvek Bags Clay Desiccants
Desi Pak®clay desiccant bags contain a highly activated, chemically inert and non-corrosive desiccant which absorbs moisture vapor through the capillary action of adsorbent particles without changing the physical shape of the particles or the bag; Desi Pak®unit bags exceed the requirements of Mil-D-3464E in actual performance and will exceed the moisture vapor adsorption of silica gel at government specifications levels. Desi Pak®montmorillonite clay is a naturally occurring mineral as opposed to the chemically synthesized adsorbent. Therefore it is more economical than silica gel or molecular sieves.
