[2][3][4][5] The technology behind Humidipak was co-engineered by formulations chemist Albert Saari and by Robert Esse, a packaging expert, in 1996.
Humidipak Inc. was re-branded as Boveda Inc. in the International Premium Cigar & Pipe Retailers Association (IPCPR) 2012 convention.
[12][13] The air, in turn, serves as the transfer medium to moderate the water content of articles in the container, such as a wooden musical instruments, food, cigars, or cannabis.
For example, at 20 °C, a saturated solution of table salt in distilled water will produce a relative humidity of approximately 75% within a container.
The pouches are made of a material that is permeable to water vapor but not to the solution within, such as flashspun high-density polyethylene fibers ("Tyvek").
To minimize leaks in the event a pouch is damaged, the solution is thickened with an agent such as hydroxyethylcellulose, xanthan gum, or alginate, to produce a hydrocolloid.
Numerous companies use the Boveda technology in their product packaging to maintain relative humidity throughout the supply chain.
