Sustainable packaging solutions
Steel packaging is strong, lightweight, and completely protects its contents from light, air and water.
It is the only packaging material for heat-processed food that maintains the condition of nutrients without the need for additives and preservatives.
Using steel packaging for food reduces greenhouse gas emissions over the entire life cycle, particularly when compared to food preparation by freezing, and its long shelf life reduces waste.
Lightweight solutions
Advances in steelmaking and manufacturing technologies have enabled the development of increasingly lightweight steel packaging solutions, which require less raw material and energy to produce, thereby reducing their carbon footprint. The weight of a 33cl beverage can has been reduced by 40% compared to 30 years ago and the average 25ml food can is now 35% lighter than 20 years ago.
We are working with our customers to further optimise the design and manufacturing process for steel packaging. Our expertise in simulating material behaviour using computer models allows us to identify material gains, for example by reducing the weight of aerosol can ends by up to 30%.
Steel packaging already meets the highest food safety standards, though we are continually researching new coating systems. Protact® is a polymer-coated steel that provides improved corrosion resistance against aggressive acid and chemical can contents, and offers further improved colour characteristics.
