BOV - Bag On Valve
What is bag on valve aerosol technology?
Many people think that “aerosol” refers to the propellant used to push the product out of the valve. However, an aerosol is the suspension of fine solid or liquid particles in a gas. So, “aerosol” actually refers to the product that is dispensed. Traditional aerosol cans mix the propellant and the liquid product when sprayed. With bag on valve (BOV) aerosol cans, the product and the propellant are separated so only the product is dispensed.
The bag is welded to the aerosol valve and then shoved inside the can which is made of either aluminum or steel. The product is squeezed into the bag, while the propellant is filled into the space between the can and the bag. When the actuator is pressed, the product is squeezed out of the bag by the propellant.

So, “aerosol” actually refers to the product that is dispensed. Traditional aerosol cans mix the propellant and the liquid product when sprayed. With bag-on-valve (BOV) aerosol cans, the product and the propellant are separated so only the product is dispensed. The following are some of the benefits of BOV aerosol cans:
-
Up to 99% of the product is emptied.
-
The product is protected from oxygen exposure, which increases its shelf life.
-
The product can be sprayed from any angle, even upside-down.
-
There is no chilling effect to the product when it is dispensed.
-
The product can be dispensed in any form, such as liquid, foam, gel, or cream.
-
Aerosol cans are hygienic and sterile because there is no need to touch the product.
BOV Technology Market– Opportunity Analysis
Increasing applications of bag-on-valve packaging in the food and beverage industry will boost the market growth of bag-on-valve technology since it is suitable for packaging food products because it retains freshness and purity. In addition to providing integrity and a long-lasting freshness for the food product, bag-on-valve also allows it to be used precisely and efficiently.
Increasing popularity of non-spray BOV products is expected to offer lucrative growth prospects for the BOV market, as they provide high efficiency with fewer contaminants. It is ideal for products like cooking oils, coffee concentrates, flavorings, and wound washes because the content dispenses in a pouring manner. The non-spray BOV product is gaining a lot of traction in the market, which is expected to stimulate the BOV technology market growth.
Aerosol delivery systems use an aluminum can, which is filled under pressure with the product you are delivering, and injected with gas. Basically, when you push the nozzle and release the contents, the product you are trying to deliver is mixed in with the gasses. As a result, the gasses evaporate, leaving the “scent” or “hairspray” behind.
As an alternative, a bag-on-valve system, also known as BOV, is used. With this system, a bag is inserted into the aluminum can and filled with what you are trying to deliver, in this case, cooking oil. When you are ready to spray a can of this spray, all that comes out of it is the stuff that is in it. It comes out under compressed air pressure, however. A pressurized air system is then added to the can, enabling you to spray only what you intend. There is no mixture, only pure product. In fact, it’s quite fascinating!
