Ball Corporation has announced a breakthrough for the use of recycled aluminium in the manufacture of extruded aluminium packaging for aerosols. The resulting new metal alloy exhibits increased strength and allows light weighting of the container without affecting package integrity. Ball’s technology breakthrough, announced in April, will allow the company to lightweight its extruded aluminium aerosol packaging by as much as 10 per cent, with further light weighting in the future. Currently, almost all extruded aluminium aerosol packaging is made from virgin aluminium ‘slugs’. These metal disks are impact extruded to produce packaging for aerosol products ranging from body sprays, sun screens, air fresheners and numerous other markets. Ball, the world’s largest producer of aluminium slugs and of recyclable aluminium beverage cans, will use aluminium recycled from Ball’s global beverage can operations to produce the company’s new slugs.
