Bag-on-valve is a relatively recent development in aerosol delivery. The principle is simple in that, instead of filling a can with a mix of liquid material and propellant(usually inflammable), the liquid material is sealed inside a collapsible inner bag and is expelled by a pressurized gas. Unlike traditional aerosols, the gas remains inside the can and, as it is usually pressurized air, the gas has no 'end-of-life' environmental impact.
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.
Components of Bag on Valve Packaging
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.
Application of Bag-on-valve
Cosmetics:Deodorants, Lotions, Shower gels, Shaving gels, Shaving foam, Facial wash, Self tanning sprays, Intim hygiene, etc.
Pharma & Medical Devices: Eye Wash Spray, Emollient Spray, Saline /Seawater Nasal Spray, Throat Spray, Medical Adhesive Remover, Auricular Spray, Wound irrigation, Contamination Control Spray, Burn Gels, etc.
Food & Nutrition: Cooking oils, Cheeses, Flavor sprays, Food supplements, etc.
Miscellaneous: From fire fighting to car care.
Benefits of Bag on Valve Packaging
The unique Bov system is developed to not only produce a superior spray dispensing system, but to reduce our ecological footprint through a sustainable packaging process. Compared to traditional aerosol spray technology (and other alternative packaging) BoV aerosols have several benefits, for manufacturers, consumers as well as the environment.
