Lightening the mood

Light-weighting is yet another of steel’s environmental strengths. Increasingly, lighter steel packaging solutions require less raw material and lower energy consumption to produce.

Over the years, the average weight of steel in its various packaging applications has been vastly reduced. Steel for packaging continues to improve its weight-to-performance ratio, thanks largely to successful progress in down-gauging.

The weight of a 33cl beverage can has been decreased over the years, resulting in a can which is approximately 40% lighter than it was 30 years ago. This decrease in mass is enabled by new steelmaking and can-making technologies and by the development of advanced steels that can offer the strength and formability required to make the packaging lightweight.
