67 Gram Boveda 2-way Humidipak Technology
How 2-way humidity control works
2-way humidity control works by continually responding and adjusting to the outside temperature and climate by either adding or removing humidity as needed to maintain a predetermined level of relative humidity (RH) inside of packages and containers. Maintaining an ideal and constant relative humidity means your product won’t lose or gain any moisture. Instead, it’ll be maintained at its ideal moisture level throughout its intended shelf-life and/or usage-life. Furthermore, it’ll never encounter any moisture fluctuations along the way.
Accuracy to (+/-) 1% by responding to temperature & climate changes
The Humidipak is different than all other technologies. Any product or material placed into a container with a Humidipak inside will be kept at the desired humidity level, +/- 1%. If the humidity in the chamber falls below the desired level, water-vapor will pass into the chamber to restore the humidity. Also, if the humidity is greater than the desired level, the Humidipak will absorb enough of the excess moisture to restore the desired humidity.
Humidipak’s 2-way humidity control technology has been awarded several broad-based patents, both U.S. and International, in the field of non-electronic control of relative humidity within enclosed containers and packages. The patented technology is referred to as Humidipak.
Natural, safe and environmentally friendly
The foundation of the technology is based on a property well known to physical chemists. It combines the formulation of a saturated solution of a soluble substance designed to maintain a specific level of relative humidity. The product consists of a gelled, saturated solution that is filled into a pouch (or other form) with very high water-vapor transmission permeability but does not allow liquid-water to pass through or leak into the container.
