What does it do? ? It keeps your product at a stable relative humidity, not too wet and not too dry. Our MoisturePak® has been designed to maintain a 62% relative humidity ±3% (RH) inside a sealed container such as a jar or bag.

How does it do that? The MoisturePak® is a two-way sorbent that uses a combination of plant fibers, water and salts to control the humidity by taking up or adsorbing the water vapor inside the container. If it is above the target RH% range, it can also generate water vapor to increase the humidity in the event that the RH level inside is less than ~62%.

Why would I need it? If your product needs a stable RH level to maintain freshness and to prevent product degradation, such as flower, hops or anything similar this is the right product for you.

What are some common applications?

  1. Musical instruments made from wood
  2. Humidors
  3. Plant based products that need to be kept from being too dry

What if I want to be completely dry the container? To obtain the lowest possible RH inside a container you will need a desiccant. We’re a company founded on sorbents and have many, many desiccant types and configurations available. Please follow this link to learn more:

Desiccant Calculator

Use this desiccant calculator to determine the quantity of desiccant you need. Please note: IMPAK recommends this as a starting point, not as a replacement for speaking with one of our trained specialists.

Desiccant Comparison Chart

By comparing the properties and capabilities of each desiccant product, it is possible for you to identify the correct desiccant for your needs and make a clear choice. Use the description and chart on this page to compare desiccants such as molecular sieve, silica, and montmorillonite clay.

Desiccant Selection Guide

When dealing with moisture problems in packaging, a wide array of variables can make it difficult or confusing to develop solutions. These variables can be classified into two main groups:
1) those pertaining to the product, its package, and the environment;
2) the physical and chemical properties of commercially available desiccants.
