Bag On Valve: Separating Your Aerosol Product From The Propellants

Many companies spend millions of dollars every year developing, manufacturing and approving their products. Some companies will turn to aerosol packagings to house their healthcare products. But have you ever wondered what is used to drive the product out of the can?

Traditional aerosol cans are designed to mix the propellant with the product. Therefore, what cost your company a lot to develop, manufacture and approve, must then be mixed with a Bag On Valve Spray Canpropellant to dispense your healthcare product.

Bag on Valve, is used as an alternative method to package pharmaceuticals and medical devices. Unlike traditional aerosol packaging, Bag on Valve (BoV) keeps the product separate from the propellant, housing it in a film laminate bag, which is welded to an aerosol valve. Therefore, your precious product maintains its integrity and remains separate from propellants at all times.

How Bag on Valve products are manufactured

Standard BoV packaging covers a broad range from 30 to 500 ml containers. BoV typically uses standard aerosol aluminium cans with 1 inch can openings, together with foil-based packaging bags of four-layer film laminates (for instance PET/ALU/OPA/PE). The film laminate bag is welded to the aerosol valve, which is crimped to the aerosol can in the filling process.

Due to the low permeability rate, BoV is also compatible with commercially available liquefied propellants. These propellants make good choices for products that call for a steady dispensing rate over the life of the can, such as post-foaming gels and creams.

What products are suited for Bag on Valve packaging?

Almost all fluids and more viscous products can be filled into a BoV system, as long as the product’s viscosity is low enough to get it through the valve stem. However, the system does not work well with products that need to be shaken before use, since the bag is filled and doesn’t improve mixing when shaken.

Keeping your product pure

When choosing your next aerosol spray medical device packaging, we suggest you talk to the Bag on Valve specialists and see if your product is best paired with BoV packaging.


Why BoV Packaging is Superior to Traditional Aerosols

BoV vs Traditional Aerosols

Why BoV Packaging is Superior to Traditional Aerosols

To many consumers that enter a supermarket on a daily bases, the quality of an aerosol can may just be another concern that goes overlooked. However, to the industry buyers and manufacturers, an aerosol can can be the difference between an average product and a premium product.

The superior Bag on Valve (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, BoV aerosols have several benefits for manufacturers, consumers and the environment.

The following are more reasons you should trust BoV as your first choice for aerosols and airless packaging.

Product Emptying – up to 100% product emptying!

Unlike traditional aerosols, BoV keeps product separate from propellants at all times thanks to an FDA-approved laminated bag installed inside the aluminum can. Because the product is in a flexible pouch, the propellant (compressed air or nitrogen) is able to squeeze the bag until almost 100% of the product is dispensed. Unlike traditional aerosols, which may run out of propellant before all of the product is dispensed.


As opposed to flammable propellants used in traditional aerosol systems, BoV uses compressed air or nitrogen to push the product out of the Bag on Valve system. This is possible because unlike traditional aerosols, BoV propellants will not mix with the product.

Product Types

In the medical sector Bag on Valve products are able to dispense as either; liquid, gel, ointment or cream. In some cases, companies can turn their pharmaceutical cream into a spray by using the BoV system. The versatility of BoV even allows products to have several other benefits;

  • Sprayed evenly at all angles

  • No pumping motion required

  • Reduced spray noise

  • Longer shelf life for oxygen-sensitive products

  • Suitable for both liquid and viscous products

  • Can be used with standard actuators and aerosol cans

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.

Bag-on-Valve (BoV) is a barrier packaging technology for companies with liquid or viscous products, looking to stand out from the competition.

Why not use traditional aerosols? In comparison to traditional aerosols, BoV separates your product from the propellant, keeping your product pure. BoV packaging is 100% recyclable, leaving a low ecological footprint. And most importantly, Bag-on-Valve is convenient and reliable for the end user.

Still not convinced? The following is a brief overview of how companies, like Aurena Laboratories manufacture and package Bag-on-Valve products.

How the Bag-on-Valve manufacturing process works

Bag on Valve Contract ManufacturersStandard BoV packaging covers a broad range from 30 to 500ml containers. Typically, BoV uses standard and fully recyclable aerosol aluminium cans with 1 inch can openings, together with foil-based packaging bags of multi-layer film laminates (for instance PET/ALU/OPA/PP). The bag is welded to the aerosol valve, which is crimped to the aerosol can in the filling process.

When the valve is crimped to the can the propellant, compressed air or nitrogen, is  filled into the area between the bag and the can, keeping product and propellant separate at all times. This pressurising process is called under the cup gassing (UTC). The product in the bag encompasses 60 per cent of the can’s brim capacity, while the remaining 40 per cent is occupied by the propellant.
