Bag-on-valve aerosol filling is the process of filling a flexible bag with a liquid or semi-liquid product and then sealing it inside a metal aerosol can along with a propellant. The bag is separated from the propellant by a valve, which controls the dispensing of the product.
The process typically involves several steps:
- The flexible bag is placed inside the metal can and the valve is attached to the top of the can.
- The product is then filled into the bag through a filling nozzle.
- The bag is then sealed and the can is filled with the propellant.
- The valve is then crimped onto the can to create an airtight seal.
The filling process is typically done using specialized equipment and automation to ensure accurate filling and consistent quality.
Once the can is filled, it is ready for dispensing. When the valve is actuated, the propellant pushes the product out of the bag and through the valve, dispensing it into the air as a fine mist or spray.
BOV aerosol filling technology is a versatile solution that can be used in a wide range of industries, including personal care, food and pharmaceuticals. Due to its consistent and controlled dispensing, it is ideal for products that require precise application, such as hair sprays, insect repellents and cooking oils.
