The Bag-on-Valve (BoV) aerosol system is a modern packaging technology developed to improve a wide range of personal care and cosmetic products. It is convenient and user friendly, and can be sprayed evenly at all angles, with a 99% evacuation rate.
With a BoV system, the product is placed inside the bag while the propellant is filled in the space between bag and can. The product — such as a gel, cream or spray — is dispensed by the propellant simply squeezing the bag when the actuator is depressed. As a result, the bulk maintains its integrity and remains separated from the propellant at all times.
