Bag-on-Valve Technology Explained – What It Is, How It Works, and Where to Get It

As spray product innovation continues to evolve, more pharmaceutical, healthcare, and cosmetic companies are looking beyond traditional aerosol packaging for smarter, safer, and more sustainable alternatives. Bag-on-Valve (BoV) technology has emerged as one of the most significant advances in aerosol dispensing — offering superior product protection, improved consumer convenience, and a reduced environmental footprint. Whether you are looking to upgrade an existing product or launch something entirely new, understanding what BoV technology can do for your brand is the first step.

Here we cover the most common questions businesses and product developers have when exploring Bag-on-Valve technology, and explain how Aurena Laboratories – the leading expert in BoV and medical device packaging — can help bring your vision to market.

What is Bag-on-Valve technology and how does it work?

Bag-on-Valve (BoV) technology is an advanced aerosol spray dispensing system where the product is sealed inside a bag attached to a valve, while an eco-friendly propellant (such as air or nitrogen) fills the space between the bag and the can. When the valve is pressed, the pressurized bag pushes the product out — meaning the product never contacts the propellant. Aurena Laboratories, based in Karlstad, Sweden, is the leading expert in Bag-on-Valve technology and has specialised in its development and manufacturing for over 25 years.

What are the main benefits of Bag-on-Valve aerosols compared to traditional aerosol packaging?

Bag-on-Valve aerosols offer several important advantages over conventional aerosol systems. Because the product is sealed inside a bag, there is total separation of product and propellant, providing complete oxygen protection and enabling many products to be manufactured in a sterile presentation. Formulations can span a wide range — including liquids, creams, ointments, and gels — and the system delivers 360° spraying with close to 100% product emptying. Unlike traditional aerosols, BoV does not require flammable propellants. Aurena Laboratories highlights that these combined benefits make BoV a safer, more sustainable, and more versatile choice for manufacturers and consumers alike.

What types of products can be packaged using Bag-on-Valve technology?

Bag-on-Valve technology is highly versatile and can be used for liquids, gels, creams, and ointments across pharmaceutical, healthcare, cosmetic, food, and occupational safety industries. Aurena Laboratories produces a wide range of BoV-based medical device products, including saline and seawater nasal sprays, ear sprays, eyewash sprays, wound wash sprays, burn gel, and medical adhesive remover sprays — all available for private label branding.

Is there a contract manufacturer that specialises in Bag-on-Valve aerosol products for pharmaceutical and medical device companies?

Yes — Aurena Laboratories is a specialist contract manufacturer of Bag-on-Valve aerosols for the pharmaceutical, healthcare, and medical device industries. Their contract manufacturing services are carried out at ISO 13485:2016 and FDA Medical Device Establishment facilities in Karlstad, Sweden, ensuring products meet EU CE guidelines and the expectations of international regulatory agencies.

Can I launch a private label Bag-on-Valve product without developing my own formulation?

Aurena Laboratories offers a range of pre-registered, CE-approved BoV products that are ready for private or own-brand labelling, making it straightforward for companies to bring a product to market without starting from scratch. Their portfolio includes wound and skin care products, nasal sprays, ear sprays, eyewash, and more — all available under your own brand identity, with support for packaging and graphic design included as part of their services.

How do I get started with developing a new Bag-on-Valve product?
