Frequently Asked Questions
A desiccant is a dehumidifying agent which attracts moisture from the atmosphere. It adsorbs and holds particles of water to itself. The three most common types of desiccants are clay, silica gel, and molecular sieve.Desiccants attract moisture vapour from the atmosphere, adsorb the molecules of water and hold them without changing their physical form. Desiccants are safe, non-toxic and non-dusting sorbent packaging solutions that provide exceptional moisture adsorbing capacity. With a number of desiccant types available, versatile desiccant capsules, packs and bags can protect a variety of packaged products from the effects of moisture including caking, mildew, fermentation, potency loss and decreased shelf life. Desiccants are available with Silica Gel, Indicating Silica Gel, Molecular Sieve, and Indicating Molecular Sieve in addition to active carbon for the elimination of smell and oxygen
Desiccants is a commercially available industrial product used for a wide variety of drying applications in the pharmaceutical, electronics, optics, laboratory, and other fields. Extends shelf life and efficiency of products by preventing moisture damage. In addition to protecting products from moisture, desiccants are also effective at absorbing odors an
Products vulnerable to moisture damage need special protection during storage and transport to ensure that they remain effective. Desiccants provide a simple, dependable and economical solution for preventing moisture damage . A popular desiccant configuration in the pharmaceutical industry, desiccants are also ideal for protecting nutraceuticals, diagnostics, electronics and food

Multisorb deals mostly with three types of desiccants and occasionally with a fourth. The most commonly used desiccants are clay, silica gel and molecular sieve, oxygen adsorbents
Silica gel is silicon dioxide (SiO2). It is a naturally occurring mineral that is purified and processed into either granular or beaded form. As a desiccant, it has an average pore size of 24 angstroms and has a strong affinity for moisture molecules. The silica gel will pull in moisture at temperatures up to 105C. As temperature goes above 100F, the rate of moisture pick-up will slow down but the silica gel will still work. Silica gel performs best at room temperatures (70 to 90F) and high humidity (60 to 90% Rh) and will drop the relative humidity in a container down to around 40% Rh. Silica gel is commonly used in food and pharmaceutical applications as only silica gel has been approved by the FDA for direct contact with these items
There are four sources of moisture contamination inside a product package.
• Moisture trapped in the air inside the package.
• Moisture contained by the packaging material itself such as boxes of carton, paper, or plastic.
• Moisture contained by other material contained in the packaging such as foam, paper, carton, cushioning materials.
• Migration of moisture from outside into the packaging.
Warming up air sucks moisture from its surrounding materials. When air cools, water vapour condenses into dew drops that contaminate your product. All these factors contribute to a product’s environment inside the package and must be carefully considered in determining the right amount of desiccant to be used
You need to use desiccants if your products can possibly be damaged by moisture in the form of corrosion, rust, molds, mildew, fungus, swelling, deliquescence and other undesirable factors affecting product integrity. Industries like electronics, semiconductors, pharmaceuticals, diagnostics, metal parts, machine parts, bulk chemicals, leather and food are among those who normally use desiccants as part of their packaging standards
The most efficient and effective way to use desiccant is to keep your product package well-sealed. This will allow the desiccant to work only on air existing inside the package, and will not include new air coming in from outside. Less desiccant is needed, humidity is largely reduced, and desiccant effectivity time is much longer when a well-sealed package is u
The Desi-Cap is a small cylinder normally made of a hard type of plastic, filled with silica gel. The humidity enters the silica gel through a carton disk and to a lesser degree through the cylinder wall. Its application is normally inside a bottle or jar . Its active live is during shelf time and after the initial opening of the container until the product is finished.
The Desi-Sac is made of paper or non woven fibre. The humidity enters the silica gel through the bag material. Its application is with strip packages sealed inside an aluminium foil. Its active live is during shelf time and before first opening of the product packaging.
The Desi-Bag is made of woven material. The application is for bulk packaging in Barrels, containers or to electrical Cabinets. Its active life is during transportation and storage of the article to be protected
