Metpack speaks of the resurgence of the metal packaging industry

The recyclability of metal packaging is worth discussing

From left to right: Alexander Hinterkopf, managing director Hinterkopf, Wolfgang Niemsch Chair of the Metpack Committee and managing director of Lanico Maschinenbau Otto Niemsch, Claudia Bierth chair European Affairs Commission at Metal Packaging Europe and managing director of the Forum Beverage Can (Germany), and Oliver Kuhrt CEO Messe Essen.

Visiting Metpack for the third time after a gap of six years reveals a new perspective for an industry that has become niche (read small and slow growing) compared to the rest of the packaging industry. Nevertheless, metal packaging is a stubborn and self-confident segment worldwide and not as small as one might have guessed. It represented a turnover of US$ 108.8 billion in 2020 and, according to research firm Global Opportunity Analysis, is expected to reach US$ 147.4 billion in 2030 with an average growth rate of 3.1% between 2021 and 2030.

The seeming or possible resurgence of metal packaging is broadly characterized by three things – the growth of a wealthy consumer class in developed and emerging economies that uses it for personal care, food, and beverage products. In developed economies, the higher cost of steel or aluminum is easily borne upfront by mass consumers while in emerging economies metal packaging makes products more expensive and is thus used for luxury products such as personal care, food, and smaller and smaller cans of beverages – in these markets, it is an aspirational badge of youth, status, and wealth.

Technology improvements

The second possible cause of the resurgence is what Metpack is mainly about – technology. Metal containers have become lighter and thinner, and the coatings, sealants, caps, and closures have become handier and more elegant. The processes of containment, preservation, and logistics have become more efficient.

The coating and decoration technology has become snappier and more efficient using new plasma surface treatments, lacquers, inks, and haptic coatings with the inherent base material for the metallic looks and texture that all other packaging is hankering after. Digital printing has made small runs for craft beer and small wineries possible.

Alexander Hinterkopf, the managing director of the company by that name that manufactures the digital presses for cans, spoke on 2 May 2023, the opening day of the event, about the resurgence of metal packaging, “Metal has become sexy again.” We have seen the Hinterkopf digital can printing machines at three Metpacks now (and there was also an Italian competitor at the last show six years ago) but for the company founded in 1980, there is currently some market traction with its new generation print heads capable of 1800 dpi. However, improvements based mainly on better inkjet arrays imply that as soon as the concept of small directly printed tubes and containers catches on, there may be competitors.

Recycling enabled by the high value of metal packaging

This brings us to the third impetus for the current wave of optimism in an industry that generally seems reconciled to remaining a niche – a special and specialized industry quite in harmony with the practices of metalworking and comfortable that it is as indestructible as the material it uses. “Metal is always superior” for packaging, said Hinterkopf at the opening Metpack conference. The third impetus is related not only to the metal’s superiority as a container, but its recyclability and its higher cost. Another speaker said the concerns of climate change that make the recyclability of packaging an imperative provide, “a tailwind” to the current compounded interest in metal packaging.

In Europe, as Claudia Bierth said at the opening press conference, the current regulations on packaging recyclability exempt wine, aromatized wines, and spirits from the normal obligations of recycling their packaging. Suffice it to say that glass, which is widely used in this sector, is a carbon-intensive, weighty, and fragile product for logistics, and a nightmare for collection and recycling in which it uses much more energy than in the recycling of aluminum.

The real opportunity in developing or emerging economies, as I see it, is that collection of all or most paper-based and plastic packaging suffers from its low value, while metal packaging has high value and can bring real incomes to waste collectors and sorters. Metal packaging is already being collected far more efficiently in India for instance than mixed polymer plastic packaging, which is deficient in weight and value – because it is impossible to identify the laminates for the right waste stream or to separate them for lateral recycling. Single polymer recyclable laminates with the right barrier properties are still fighting a battle with an overly cost-conscious consumer product industry, while advanced or chemical recycling of mixed plastic waste seems to still be in its infancy, globally.

The wine and spirits industries are quite full of themselves globally. Leave aside the ubiquitous wine and spirit industry lobbies in Europe that have managed to exempt themselves from recycling regulations through their strong lobbying of the regulators. This sense of entitlement is globally widespread. For instance, in India, the substantial global spirit supplier Pernod Ricard has done away with the cartons it used to ship its bottles in. Speaking of this as a great environmentally conscious move, it has blithely forgotten that it is a major user of heavy, fragile, and energy-consuming-to-recycle glass bottles for the burgeoning liquor industry.

The impact, resilience, and growth of responsible packaging in a wide region are daily chronicled by Packaging South Asia.

A multi-channel B2B publication and digital platform such as Packaging South Asia is always aware of the prospect of new beginnings and renewal. Its 16-year-old print monthly, based in New Delhi, India has demonstrated its commitment to progress and growth. The Indian and Asian packaging industries have shown resilience in the face of ongoing challenges over the past three years.

As we present our publishing plan for 2023, India’s real GDP growth for the financial year ending 31 March 2023 will reach 6.3%. Packaging industry growth has exceeded GDP growth even when allowing for inflation in the past three years.

The capacity for flexible film manufacturing in India increased by 33% over the past three years. With orders in place, we expect another 33% capacity addition from 2023 to 2025. Capacities in monocartons, corrugation, aseptic liquid packaging, and labels have grown similarly. The numbers are positive for most of the economies in the region – our platform increasingly reaches and influences these.

Even given the disruptions of supply chains, raw material prices, and the challenge of responsible and sustainable packaging, packaging in all its creative forms and purposes has significant headroom to grow in India and Asia. Our context and coverage engulf the entire packaging supply chain – from concept to shelf and further – to waste collection and recycling. We target brand owners, product managers, raw material suppliers, packaging designers and converters, and recyclers.
