“Emissions shrinker” aerosol top

How a strong partnership leads to a win-win and breakthrough solution.

ArcelorMittal has partnered with longstanding customer Massilly to develop an innovative low-thickness aerosol top from high strength steel, that delivers a 10% reduction in material steel content per component, and so a substantial reduction in the raw material’s embedded carbon footprint – effectively an “emissions shrinker.”


ArcelorMittal has a long-standing partnership with French-based Massilly Holding S.A.S., a global player in metal packaging for the consumer and industrial markets. Massilly is committed to the advantages of metal packaging products for their qualities of durability, safety and recyclability.

This particular project was founded on both companies’ mutual objective of pioneering downgauged steel in aerosol applications, to reduce materials, costs and carbon emissions.

The new top has won the 2026 ADF Innovation Award certificate which was handed over during Paris Packaging Week, on 6 February 2026, at the Paris Expo, Porte de Versailles.

“Reducing the thickness of our metal packaging is an invisible innovation that represents a major technical challenge: achieving significant resource savings while maintaining the full structural integrity and protective properties of our products. We thank the ArcelorMittal Global R&D team for their collaboration and commitment to helping us make this breakthrough possible,”

says Valérie Bindschedler, Massilly’s Marketing Director.

“We have introduced a new high strength steel (HSS) range - covering 600, 620 and 650 MPa yield stress,” commented Richard Lézé, Chief Marketing Officer, Packaging Europe, ArcelorMittal. “This has enabled us to consider some extreme downgauging product developments. It matched perfectly with Massilly’s plans, and enabled us to co-develop a new high-strength, low-weight aerosol top. The aim was to achieve maximal lightweighting without sacrificing safety performance, whilst maintaining the required 15 bar pressure resistance.”

The result has been moving with Massilly’s product development team from a standard 0.29 mm steel thickness to a new best-in-class benchmark of 0.26 millimetres for a D48 aerosol top, a 10% material reduction per component.

ArcelorMittal Global R&D, working with the Packaging team, undertook Finite Element Analysis (FEA) to fully redesign the aerosol dome profile with Massilly, to concentrate strength exactly where it is needed for pressure resistance.

For both companies this innovation is a powerful contribution to climate mitigation and circularity, delivering immediate CO2 savings through the reduction in steel mass, and allowing for full recyclability at the product’s end of use.
