MiniPax® Sorbent Packets

Protect Shipped Packages with MiniPax® Moisture Absorbing Packets

MiniPax® Desiccants | For Those That Demand the Best!

There’s a saying that big things come in little packages and MiniPax® moisture adsorbing packets are no exception. Unlike cheaper alternatives these sorbent bags continue to prove themselves as a ‘best in class’ moisture absorber product.

Simple, dependable and proven effective, MiniPax® desiccant packets protect sealed containers/products susceptible to moisture damage along the distribution chain and are ideal for both automatic or hand packaging operations.

MiniPax®  are compact, extremely durable, non-dusting sorbent packets which take up little space in packaging yet have high moisture adsorbing capacity. MiniPax® packets are offered with a variety of sorbent blends and sizes (0.25 grams to 28 grams)  to meet specific packaging needs for a wide variety of packaging applications. Learn more about MiniPax® competitive advantages below.


  • High Strength: MiniPax® packets are formed of welded, uncoated, pharmaceutical-grade Tyvek®, an extremely tough and durable sheet of spunbonded HDPE fibers only available from Dupont. MiniPax® has very high tear strength in all directions and is virtually puncture-proof to eliminate any risk of leakage and product contamination.  MiniPax® is unaffected by water or moisture and is as strong wet as it is dry. It will not rot or mildew.
  • Controlled Porosity | High WVTR:  A high water vapor transmission rate (WVTR) make the material ideal for MiniPax® sorbent packets. Porosity of the outer barrier envelope is closely controlled during the manufacturing process to assure consistency batch after batch. This eliminates any variation in the allowable handling time of a MiniPax® packet.
  • Non-Dusting | Non-Linting:  The dense packing of the fine Tyvek®  fibers forms a tight barrier to particulate matter and prevents sorbent dusting. MiniPax®  drop-n-go packets have a stable, abrasion resistant surface and are non-linting.
  • Odor & Moisture Adsorption: MiniPax® is permeable to odors and gases, thus a MiniPax® packet containing an appropriate sorbent blend can be used for both odors and moisture protection.
  • FDA & USDA Status | ISO9001 Certified:  Made in an ISO9001 certified USA factory, the pharma grade Tyvek® used in MiniPax® construction is chemically inert, non-dusting and can be used in food packaging applications. MiniPax® are supported by a Type III DMF, use 21 CFR-compliant materials, and are suitable for use in all regulated product packaging.

  • Compact:  The low profile and compact shape of MiniPax® sorbent packets saves space and displaces a minimum amount of product. Its flat contour design eliminates any potential confusion with capsule or a pill.
  • Maximum Surface Exposure: The exceptionally narrow seal skirt on only two ends gives MiniPax packets an unusually large adsorptive surface area for its overall size
  • Integral Window: An integral transparent strip permits easy monitoring of the contained adsorbent and allows effective use of indicating desiccants to show when moisture has been adsorbed and when desiccant should be replaced. (MiniPax® Indicating Silica gel is not for use with food or pharmaceutical packaging).

Silica Gel  Features:

  • Typically used in food and pharmaceutical applications
  • High Crush strength and high porosity
  • Remains dry and free flowing even when saturated
  • Chemically inert, non-corrosive and non-toxic

Indicating Silica Gel Features:

  • Color changes from blue to pink to indicate moisture content
  • Similar features as silica gel above
  • Indicating silica gel is not intended for food or pharmaceutical packaging

Molecular Sieve Features:

  • Uniform adsorption pore size makes it an excellent getter for water
  • Added capacity to adsorb organic odor causing molecules

Clay (Montmorillonite) Features:

  • Produced by the controlled drying of montmorillonite, a naturally occurring mineral
  • Essentially non-swelling
  • Can both take on and give up moisture without deterioration

Activated Carbon Features:

  • Foremost getter for organic molecules and sulfur-bearing compounds
  • Primary application is color or odor removal

Moisture/Odor Blends Features:

  • Mixtures of clay or silica gel with activated carbon on a 50/50 or 60/40 ratio
