The Bag-on-Valve consists of a rolled-up multi-layered flexible pouch attached to an aerosol valve. In the production of a BoV product, compressed air or nitrogen is charged into the can, and an aerosol valve with the bag attached is crimped onto the container. The formulation is forced through the  aerosol valve stem to fill the bag. When the spray button is pressed, the product is squeezed out the bag by the compressed air/nitrogen, which creates the dispensing as a spray, cream or gel.

As such, BoV is an ideal barrier pack for liquids, gels, creams and lotions, keeping high product integrity and protection against oxygen.

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.

Safety and environmental benefits of BoV aerosols 

• No need for flammable propellants
• Hygienic and sterilisable
• Used with eco-friendly air or nitrogen
• Less need for preservatives

Production & Environment

Bag on Valve technology is suitable for clean room production and medical products. Companies, such as Aurena Laboratories, incorporate the clean room manufacturing process into their BoV packaging, so they can produce safe and sterile products for customers.

The advantages of BOV aerosols over the traditional propellant-mix systems fall into two distinct areas: the environmental and regulatory benefits and the usage and cost benefits.
