When choosing a dispensing system for your product, two common options are traditional aerosol cans and the increasingly popular bag-on-valve (BoV) technology. Each has unique benefits and considerations, making it crucial to select the right system for your product’s formulation, target market, and environmental impact.
Understanding Aerosol Technology
Aerosol packaging has been widely used for decades in industries such as personal care, household cleaning, automotive, and pharmaceuticals. This system relies on a pressurised canister containing both the product and a propellant, which helps dispense the contents in a controlled spray, foam, or mist.
Pros
Pros of Aerosol Packaging
- Cost-Effective: Aerosol cans are generally more affordable to manufacture compared to BoV systems.
- Proven and Versatile: Aerosols have been widely tested in various industries and are available in different formulations, from liquid sprays to gels and foams.
- Long Shelf Life: Due to the sealed nature of aerosol cans, products often enjoy an extended shelf life.
- Efficient Dispensing: Aerosols provide precise and consistent application, making them suitable for various uses.
Cons
Cons of Aerosol Packaging
- Propellant Concerns: Many aerosols use hydrocarbons or compressed gases, which can be harmful to the environment and require careful handling.
- Limited Product Usage: Aerosols can leave residual product in the can, leading to waste.
- Regulatory Restrictions: Due to their pressurised nature, aerosols may face shipping and handling restrictions.

Understanding Bag-on-Valve (BoV) Technology
Bag-on-valve (BoV) systems use an internal bag within an aerosol can that separates the product from the propellant (which is usually compressed air or nitrogen). The product is dispensed using air pressure, offering a continuous spray without the need for harmful chemical propellants.
Pros
Pros of Bag-on-Valve Packaging
- Eco-Friendly: Uses compressed air or nitrogen instead of chemical propellants, reducing environmental impact.
- Complete Product Dispensing: Unlike traditional aerosols, BoV systems allow nearly 100% product evacuation, reducing waste.
- Extended Product Integrity: Because the product remains sealed within the bag, it is less prone to contamination and oxidation, enhancing shelf life.
- Multi-Position Spraying: The product can be sprayed in any orientation, making it more convenient for consumer use.
- Ideal for Sensitive Formulations:
Perfect for pharmaceutical, food, and cosmetic products that require preservative-free or sterile packaging.
Cons
Cons of Bag-on-Valve Packaging
- Higher Production Costs: BoV packaging can be more expensive to manufacture and fill compared to traditional aerosol systems.
- Limited Formula Compatibility: Some products may not be suitable for BoV technology, requiring formulation adjustments.
- Bulkier Packaging: The added bag structure can increase packaging size slightly compared to traditional aerosols.

Choosing the Right Packaging for Your Product
When deciding between aerosol and BoV systems, consider the following factors:
- Product Type: Does your product require a continuous spray or a controlled burst? Does it need to be free from propellants or preservatives?
- Environmental Considerations: Are sustainability and eco-friendliness important to your brand and target audience?
- Cost Constraints: Can your production budget accommodate the higher costs of BoV technology, or is traditional aerosol the more viable option?
- Shelf Life and Stability: Will your product benefit from the airtight, contamination-free nature of BoV?
- Regulatory Compliance: Are there shipping or safety regulations that could impact your choice?
Both aerosol and bag-on-valve technologies offer distinct advantages depending on your product’s needs. Aerosols are cost-effective and widely accepted, making them a solid choice for many applications. However, BoV technology provides superior product dispensing, eco-friendliness, and enhanced product integrity, making it ideal for premium formulations. By assessing your product’s requirements and considering long-term sustainability, you can make the best choice for your brand and customers.
