Silica Gel and Desi Pak® Bentonite Clay Moisture Adsorbing Bags

Edition Date :
July 08, 2021

Our bentonite and silica gel desiccant bags are highly active desiccants packaged in porous materials that allow them to effectively adsorb, sometimes commonly referred to as "absorb," moisture inside packaging or storage containers helping protect packaged goods from moisture damage.

  • Desiccant bags effectively adsorb moisture in product packaging to combat its damaging effects, including corrosion, mold, and degradation.
  • Desiccant bags meet Mil-D-3464E (Mil-Spec) Types I, II, and III, as well as comply with JEDEC for semiconductor packaging (dry pack, dry packing).
  • Desiccant bags meet various global specifications: German DIN 55473 and TL 6850-0008, French specification AFNOR NF H 00321, and MIL-D3464E (Mil-Spec).
  • Clariant offers desiccant bags that meet relevant U.S. FDA specification for use in food and drug.
  • Desiccant bags are a simple, dependable, and economical solution for preventing moisture damage in enclosed packages.

Why do I need a desiccant bag?

Moisture can quickly affect the value or even destroy many types of valuable goods, causing rust, corrosion, mildew, mold and device malfunction. By sealing goods inside packaging with the appropriate desiccant, goods can be protected from moisture and maintain long shelf lives.

The desiccant reduces the humidity inside a sealed package as soon as they are placed inside.

The absorption capacity is dependent on the relative humidity (r.h.) of the surrounding air.

Desiccant Industries

Placed within a sealed package or container, desiccant bags will protect any number of products, including:

  • aircraft storage 
  • laid-up ships (lay-up vessels)
  • stacked rigs (mothballing)
  • automobile parts
  • electronics
  • electronic components (example: surface mount devices, integrated circuits, circuit boards, capacitors, and resistors) used in dry pak per JEDEC J-STD-033
  • engines
  • semiconductors
  • food
  • leathers
  • packaged foods - cartons, cans, boxes
  • machinery
  • medical devices
  • metals
  • military goods
  • textiles
  • 3D Printing Filament
Available Configurations

Desiccant bags are available in a variety configurations. Standard bag sizes range from 1/6 unit to 80 units (5½ grams to 2,640 grams).

One Unit of desiccant is equal to 26 grams of silica gel or 33 grams of bentonite.
