The Bag on Valve (BOV) system consists of an aerosol valve with a welded bag.

The bag in the spray can is surrounded by compressed air which acts as a propellant of the product inside the bag. Rather than aerosol spray products, where the product and the propellant need to be mixed together, this technology offers numerous advantages.

Use of compressed air as propellant:

• is highly environmentally friendly;
• allows up to 99% product consumption;
• provide 360° continuous spraying.
