Boveda Inc., formerly known as Humidipak Inc., is a manufacturing company based in Minnetonka, Minnesota, United States. It specializes in humidity control for a multitude of industries and applications. It was founded on July 1, 1997.
The company's technologies are used by cigar companies for shipping and distributing cigars, cigar connoisseurs for storing and aging fine cigars, art museums and collectors for conserving fine art, food manufacturers for extending shelf-life and improving the flavor delivered to consumers, musical instrument manufacturers and musicians for maintaining instruments over a lifetime, to extend the shelf life of cannabis, and by users for many other applications.
The technology behind Humidipak was co-engineered by formulations chemist Albert Saari and by Robert Esse, a packaging expert, in 1996. Saari and Esse both came from General Mills Corporation. The company was then founded on July 1, 1997. The company owns patents related to two-way humidity control for packaging, including multi-purpose Humidipaks that manage moisture, absorb oxygen and control mold.
In 2008, Rocky Patel Premium Cigars started to manufacture a custom-printed Humidipak humidity control packet in order to make the cigars properly humidified. Between 2010 and 2014, Ashton Distributors Inc., was the exclusive U.S. distributor of the Humidipak and Boveda brands for the premium cigar market. Boveda now self-distributes.
Humidipak Inc. was re-branded as Boveda Inc. in the International Premium Cigar & Pipe Retailers Association (IPCPR) 2012 convention.
Boveda produces small pouches for humidity buffering of an enclosed container. The pouches consist of an aqueous salt solution within a sealed vapor barrier package that can absorb or release water vapor until an equilibrium humidity is reached between the solution and relative humidity of the surrounding air.
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. Water is transferred between the article, the pouch, and the air within the container until an equilibrium condition is reached. The relation between relative humidity of the air in the container and the moisture content of the article is complex, and can be described by a moisture sorption isotherm curve.
The tendency for the solution in a pouch to retain rather than release water vapor is determined by the composition of the salts in solution. A single-salt solution will reliably produce an environment of a known equilibrium humidity. For example, at 20 ðC, a saturated solution of table salt in distilled water will produce a relative humidity of approximately 75% within a container. Magnesium chloride will result in an equilibrium humidity of approximately 32%. Such salt solutions are accurate enough to be used to calibrate hygrometers. Other equilibrium humidity levels can be produced through mixtures of salts.
The pouches are made of a material that is permeable to water vapor but not to the solution within.
Numerous companies use the Boveda technology in their product packaging to maintain relative humidity throughout the supply chain. As of 2015, Boveda self-distributes their products for the cigar market in the United States. Internationally, Boveda has numerous distributors in Canada, South America, Southeast Asia & East Asia, Europe and South Africa. D'Addario distributes Boveda's line of Humidipak humidity control products for the music industry.
The initial market application for Humidipak was engineered for cigars. As of 2014, Boveda is carried in over 2,500 stores globally.
Because 2-way humidity control is engineered to maintain a very specific, predetermined level of relative humidity (+/- 2% RH), the technology is being used to solve moisture-related packaging problems for many different industries and applications.
Some of these new applications are herbal medicine and medical cannabis, wooden instruments, pet food, and electronics.
Boveda products are available in many relative humidity (RH) levels ranging from 32% to 83% RH.
