DRIERITE DESICCANT BAGS

These non-woven bags containing DRIERITE are used to completely dry the air within a package or container during shipment or storage. The disposable packets are dust tight and will protect enclosures for many months when used within an adequate moisture barrier. These desiccant bags are approved by the FDA and DRIERITE is Generally Recognized As Safe (GRAS).

Every box of DRIERITE Desiccant Bags comes with a 30% Relative Humidity card that changes from blue to pink when the bags are no longer active.

Typical uses of DRIERITE desiccant bags include the packaging and protection of:

  • Electronic equipment
  • Metal parts
  • Tools
  • Foods
  • Pharmaceuticals
  • Moisture sensitive materials
  • Instruments
  • Photographic equipment
  • Circuit boards
  • Appliances
  • Batteries
  • Sporting Goods
  • Guns
  • Jewelry

Materials

DRIERITE desiccant bags are filled with DRIERITE (anhydrous calcium sulfate). Available in white TYVEK® or brown kraft paper. Held together by heat seals.

Performance

A DRIERITE desiccant bag will reduce the humidity in a sealed enclosure to a -100° F dew point in about 10 hours or less. Materials packaged with these desiccant bags are protected from corrosion and other harmful effects of moisture contamination.

DRIERITE bags leave behind less residual moisture than most other types of desiccant bags. DRIERITE also performs well at elevated temperatures and will not release absorbed moisture at less than 350° F. This is an important consideration when shipping products during variable weather conditions.

TECHNICAL DATA - THE USE OF DRIERITE IN PRESERVATION AND PACKAGING

Drierite Desiccants

DRIERITE Is The Solution

The best way to prevent the adverse effects of moisture is to protect the compartment or container with a desiccant such as DRIERITE. DRIERITE is uniquely suited to this type of application, in that it will not release any of its absorbed water when exposed to high ambient temperatures. The water is securely held in the form of the hemihydrate of calcium sulfate, which requires temperatures in excess of 350° F to free the water. Other desiccants release water with any small increase in temperature.

Adverse Effects of Moisture

Water and water vapor probably cause more damage than any other contaminant, either by direct attack or by indirect means. Dampness can promote the growth of mildew or fungus. Water molecules on the surface of metals can cause rust, tarnish or corrosion. Water vapor in the atmosphere can promote chemical reactions which will corrode or destroy the material that comes in contact with the products of reaction. While the insides of a compartment or container and its contents may feel dry to the touch, a considerable amount of water may be adsorbed on the surface or in the pores of them. Changes in temperature can desorb the water and condense it into droplets causing water spots, localized corrosion or other deterioration.

Packaging Suggestions

A commonly used storage container is a corrugated carton or a wooden box. Unless they are wax-coated or resin-treated, water vapor is transmitted through them quite readily. Standard practice is to line them with a plastic film, such as polyethylene. While the plastic film will hold liquid water, water vapor may pass through it. For instance, 1-mil polyethylene will pass water vapor at the rate of 1.5 grams/sq. ft./ 24 hrs, while 4-mil polyethylene will only pass about 0.05 grams/sq. ft./24 hrs at 75° F and 100% RH. We normally recommend that you use a minimum of 4-mil polyethylene, or something equivalent to it in water vapor transmission rate.
For short term storage - two to four weeks - we suggest that you use eight ounces of DRIERITE for every 20 sq. ft. of 4-mil polyethylene, plus sufficient DRIERITE to remove the water in the contents of the bag or container. For medium term storage - one to three months - use eight ounces for each 10 sq. ft. of vapor barrier. For long term storage - three months or longer - use eight ounces of DRIERITE for every five square feet of vapor barrier. Enough extra DRIERITE will have to be added in the last two cases to remove the water in the contents of the container.
The quantities of DRIERITE recommended above are based on relatively stable storage conditions. If there are large daily fluctuations in temperature or if extremely high temperatures and high humidity are to be encountered, the amount of DRIERITE should be doubled.

How Much DRIERITE Is Required?

There are four sources of water contamination in a closed container or package: the water vapor in the air inside the package, the water adsorbed in the materials inside the package, the water adsorbed on the walls of the container, and the permeation of water vapor into the container. In order to protect the contents of a container or package from the destructive effects of water, enough DRIERITE must be used to remove all the water from these sources.
A hermetically sealed container, closed in a normal ambient atmosphere, would require approximately four ounces of DRIERITE for every 10 cubic feet of free volume to dry the air in the container. At more extreme conditions (100° F and 100% R.H.) eight ounces of DRIERITE would be required. Anything in the container that has water adsorbed in it would require extra DRIERITE. Wood and paper products can have as much as 10% by weight adsorbed water. Styrofoam and some rubber products may have as little as 0.5% adsorbed water. Once the amount of water in the material in the container has been estimated, you can calculate the amount of extra DRIERITE required by dividing the weight of the adsorbed water by 0.06. The total amount of DRIERITE required to protect a hermetically sealed container would be the sum of the amount of DRIERITE required to dry the air volume plus the amount of DRIERITE required to dry the materials in the container.
If a well-sealed container, such as a 55 gallon drum with a gasketed lid, is being used, the amount of DRIERITE required is calculated the same as for a hermetically sealed container, except that an additional four ounces of DRIERITE per ten cubic feet of volume is used to compensate for moisture permeation through the seal. To protect an enclosure such as a safe, tool box or a slip cover can, where there is no gasket, requires about eight ounces of DRIERITE per five cubic feet of volume plus the DRIERITE required to remove the water from the contents of the enclosure. The quantities of DRIERITE suggested above are predicated on the assumption that the ambient storage conditions are rather stable, and there are not large temperature fluctuations daily. If an unsealed container were stored in a area where the temperature could fluctuate 30° F daily, the container may possibly breathe 200% of its free volume per month. If this were the case, additional DRIERITE would be needed to absorb the water entering due to the breathing of the container.
