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:
