Bentonite Clay

Bentonite clay, also known as Montmorillonite clay, is another widely used desiccant. It is a naturally absorbent material made from magnesium aluminum silicate. Bentonite clay is particularly effective at absorbing moisture at low temperatures and can be regenerated for repeated use at relatively low temperatures.

However, it tends to release moisture when temperatures rise, making it less suitable for high-temperature environments. This characteristic makes it ideal for packaging that will be stored or transported in cooler conditions.

Molecular Sieve

Molecular sieves are synthetic zeolites engineered to have extremely uniform pore sizes. These pores can trap molecules smaller than their diameter, making them highly effective at adsorbing water and other gases. Molecular sieves are particularly useful in applications requiring very low humidity levels.

Best Practices for Using Desiccant Packaging Solutions

Placement in Packaging

To maximize the effectiveness of desiccant packs, placement is crucial. Desiccants work best when placed in a sealed moisture bag or container. This ensures minimal air exchange, allowing the desiccant to effectively control humidity levels within the enclosed space.

Always use humidity indicator cards inside the container. These cards help you monitor the humidity levels and indicate when the desiccant needs replacing.

Determining the Right Amount of Desiccant

Calculating the right amount of desiccant is key to protecting your products. Consider the following factors:

  • Volume of air space: Larger volumes require more desiccant.
  • Atmospheric conditions: Higher temperatures and humidity levels increase the need for desiccants.
  • Moisture surrounding the package: If the package is in a damp environment, you’ll need more desiccant.

For example, in compliance with the U.S. Military’s specification (MIL-D-3464E), one “unit” of desiccant will absorb 3.00 grams of water vapor at 20% relative humidity or 6.00 grams at 40% relative humidity at 77°F (25°C).

Reactivation of Desiccants

Desiccants can often be reactivated and reused, making them cost-effective. However, the process needs to be done correctly:

  • Temperature: Reactivate desiccants by heating them. For silica gel, a temperature range of 250°F to 300°F (121°C to 149°C) is recommended.
  • Time: The duration for reactivation depends on the type of desiccant and the extent of moisture absorption. Typically, it ranges from a few hours to a full day.
  • Maximum Reactivation Times: Each type of desiccant has a maximum number of reactivation cycles before it loses efficiency. Always refer to the manufacturer’s guidelines.

By following these best practices, you can ensure your desiccant packaging solutions work effectively to keep your products dry and safe.
