Ardagh redesigns debossing technology

Ardagh Group has redesigned its debossing technology to highlight the branding potential of embossed cans.

Ardagh first created an embossed design for the Jupiler brand in 2014, producing 330ml and 500ml cans that were debossed on their lower halves. The success was reflected both in Jupiler’s sales, and its invitation to update the design for 2019.

The latest version features debossed flutes that not only mirror the design of Jupiler’s glassware range more closely, but also provide a functional benefit. Research produced by AB Inbev (ABI) in collaboration with Diabatix, a Belgian company that specialises in generative thermal design, showed that, by reducing the surface area in contact with the drinker’s hand, the recessed relief of the full-length flutes lowers heat transfer, and so keeps the beer colder for longer.

However, product application manager of Ardagh Group’s European Metal division, John Reed, said: “Pressing a design into a can wall just 0.1mm thick, has to be done judiciously, and in the right areas. There’s no handbook for this, just the experience gained over the last 15 years of using [embossing] technology.”

A critical aspect of this technology is that the larger the area to be embossed, the shallower and less well defined the impression created by the tooling is – which made the length and depth of the flutes in the new Jupiler design a considerable challenge.

The result, was tooling capable of combining both definition and depth to create a debossed can whose detail references the Jupiler fluted glass more closely and satisfied ABI’s colder-for-longer concept.

The finishing touch, meanwhile, lies in the design’s sparing use of colour. Rather than being printed with a solid red as first intended, the Jupiler cans exploit the highlights and reflections of the bare, embossed aluminium to create a premium feel and a striking appearance that stands out among retail shelves.

“The embossing market had been dormant for the past couple of years, but it’s back in vogue again, especially among brewers,” said Reed. “Brewers are looking to create a premium brand for their beers. The production innovation which resulted from the Jupiler project has wider benefits as it gives us the opportunity to take a fresh look at embossing and allows us to create more complicated designs while still achieving strong stand-out.”
