Bag on Valve (BOV) is an innovative packaging technology widely used in the cosmetics, pharmaceutical, food, and industrial product sectors. The core of BOV technology lies in its unique design: the product is sealed in a flexible bag, which is then attached to the valve system of an aerosol can. When the valve is opened, compressed gas (usually nitrogen or air) pushes the product out of the bag through the valve, while the product itself remains completely isolated from the compressed gas.
This design offers multiple advantages. Firstly, BOV technology ensures complete isolation of the product from the propellant, preventing contamination and chemical reactions, thereby extending the product's shelf life. Secondly, since the product is only expelled through the valve, there is no residual product left in the can, significantly improving product utilization. Additionally, BOV technology allows for the use of more environmentally friendly propellants, such as compressed air, reducing the negative impact on the environment.
BOV technology also provides greater design flexibility. Because the product is separated from the propellant, manufacturers can use various types of containers and valves to meet the needs of different products. Whether it's high-viscosity emulsions, low-viscosity liquids, or suspensions containing particles, BOV technology can handle them effectively.
In summary, Bag on Valve technology not only enhances the safety and stability of products but also offers manufacturers more design options and environmental benefits, making it an important part of modern packaging technology.
