Bag On Valve Technology
The Bag-on-Valve (BoV) aerosols system is a modern packaging technology developed to improve your cosmetic, medical or food products. Not only is it convenient and user friendly, but it can be sprayed evenly at all angles and has up to 99% product emptying.

How does Bag on Valve Work?
BoV consists of an aerosol valve with a welded bag. The product is placed inside the bag while the propellant is filled in the space between bag and can. The product is dispensed by the propellant simply squeezing the bag when the spray button is pressed, the product is squeezed out of the bag by the compressed air/nitrogen, which creates the dispensing as a spray, cream or gel.

Therefore, your product keeps its integrity, remaining separated from the propellant at all times.

1. The Valve of a Bag-on-Valve
Bag-on-Valve (BOV) systems are available with both female and male valves.

2. The Bag-on-Valve Bag
Bag-on-Valve FDA-approved laminated aluminum bag (3 or 4 layers depending on product requirements). BOV systems are available in a large range of sizes.

3. The Product
Bag-on-Valve systems are suitable for liquid as well as viscous products, such as gels, creams and ointments, in a number of application areas. BOV systems are optimized for oxygen-sensitive and sterile products.

4. The Bag-on-Valve Propellant
Because of the separation between product and propellant, BOV can be used with compressed air or nitrogen.

5. The Bag-on-Valve Actuator
Bag-on-Valve are available in a large range of standard actuators depending on product demands.

6. The Bag-on-Valve Can
Standard aerosol can, aluminum or tin plate (whenever possible the use of aluminum cans is recommended). All sorts of shaped cans can be used with BOV systems. No limitation in marketing solutions.

And of course – the Bag-on-Valve Cap
