The polymer delivery system has a come a long way since Chase Products presented its first commercial incarnation in the late 1940s. This was off the back of US Department of Agriculture issuing cans of aerosol insecticide to the GIs during World War II.

Aerosol barrier pack technology is nothing new. It has been around since the 1990s with bag on valve (BoV) at the forefront of the development. Characterised by the separation of the propellant from the product, its protection from oxidants and the mixing of a product with foaming gas, pressurised barrier packs have already claimed their rightful position in cosmetic, medical, food and technical... markets, yet they are still considered a relatively new technology for many applications.

The market for two-chamber pressure packs is a large one and is primarily dominated by bag on valve systems, consisting of a can and a laminated bag, which is mounted directly on the valve. The Nussbaum can in can system replaces the can with a very thin aluminium pouch, comparable in its characteristics with an aluminium tube, which is firmly connected to the outer can.

Just southeast of Milan, in Mulazzano, an Italian family is making a proud tradition of their business. A dedication to research, development and shrewd investment has carried them through 30 years and looks to carry them a further 30. Led by Stefano Simonini, Cosmosol has been packaging and producing aerosol cleaners, insecticides and bodycare products since the 1980s. During the 1990s, Cosmosol... began to set itself apart from competitors by specialising in cosmetic and medical aerosol applications. [read more]

With conventional single chamber aerosols, propellant and product are filled into the same chamber and are therefore mixed with each other. With piston cans, the product is protected and filled separately from the propellant into the upper chamber of the piston can.

Pronounced say-so, SASO® is Springfield’s digital self-adhesive shrink-on label specifically designed to give seamless, full-height, 360? coverage of cylindrical objects. It is particularly suited to aerosol cans due to its ability to mould perfectly around the taper at the top and bottom of the can to give the impression it is printed directly on to the metal. The final effect is a... perfectly applied digital label that produces the best decorated cans available. [read more]

The aerosol product in the bag on valve (BoV) system consists of a classic aerosol container, aluminium or steel can, an actuator with an identical or similar construction to that used in aerosols, a classic cover, the cap, and a valve with a bag.
