Aluminium provides a perfect barrier against light, air and other gases, humidity, and germs and bacteria. It is also corrosion resistant. This means the can’s contents are protected perfectly against deterioration or any kind of impurity. Not only does this prevent loss of all of the resources used to produce the contents but it also provides the consumer with optimal safety and security. Unlike other forms of packaging, CO2 migration and UV radiation cannot damage personal-care products, sensitive pharmaceutical preparations or even foodstuffs when aluminium cans are used. The efficacy, odour and taste, colour and consistency of the contents, and thus their quality, remain unimpaired over a long period of time. Due to their excellent material and barrier properties aluminium aerosol cans are suitable for use with all conceivable propellants and contents. This versatility explains the can’s success in markets all over the world.
