Types of aerosol formats
Aerosol products are available in several formats and configurations. Containers are typically made of tinplate or aluminium and are available in different diameters and heights. Common aerosol applications include sprays, mousses, foams, and gels.
Propellant aerosols are our most widely used format. In this system, the product is released when the valve is activated and the propellant gas expels the contents from the container. Since the ban on freon, modern propellants used in aerosols do not harm the ozone layer.
Common propellants include:
-
Compressed air
-
Butane / propane
-
DME
-
CO₂
-
Nitrogen
Bag-on-valve (BOV) works for many different applications, from shower gels to facial mists. The formulation is contained in a bag inside the can, while compressed air or nitrogen applies pressure around it — enabling aerosol functionality without direct contact between product and gas.
Smooth, hygienic and durable
Aerosols are easy to use and allow for controlled, efficient dosing, often requiring a smaller product amount to achieve the intended effect compared to many other packaging solutions.
The pressurised container is fully sealed, which eliminates the risk of leakage and protects the product from external contamination. This ensures a high level of hygiene, as bacteria and dirt cannot enter the container. As a result, aerosols can often be formulated without added preservatives.
From an environmental perspective, the sealed system helps reduce product waste by allowing the product to be used until empty, while the containers are fully recyclable.
