A short history of aluminium closures

The smelting process to produce aluminium was discovered at virtually the same time but completely independently in 1886 by Paul Héroult in France and Charles Martin Hall in the United States. About 75% of the aluminium ever produced is still in use today.  (see also history)

Aluminium containers and foil appeared as early as the beginning of the 20th Century.  After World War I, foil packaging came to the forefront in response to consumer demand for choice and convenience that led to changes in production and distribution conditions and systems. (see also history

Since the 1960s, consumer and industrial packaging have benefited from the unique combination of properties of aluminium:  it is impermeable, odourless and non-toxic.  The first aluminium rolled-on pilfer proof closure, also known as ROPP, was introduced in the spirits market and continues to be the closure of choice.  It still accounts for nearly 70% of all aluminium closures used with alcoholic beverages.

The aluminium wine closure was invented more than 40 years ago.  Swiss wine makers were the first to use aluminium closures in large numbers. In 2000, wine makers in America, Australia and New Zealand began to convert from cork to alu closures. France, Germany, Italy, Chile & Argentina followed in 2002.

ROPP closures are also used extensively for bottled water, particularly sparkling versions, as well as food products such as olive oils where the integrity and quality of the closure is important.

The Growth of Aluminium Closure Production

  • A leading closure - on a global production of 36 billion spirits bottles, 25 billion are closed with aluminium closures - and the vast majority for bottles of quality olive oil and premium water 
  • The aluminium closure is the preferred choice thanks to the `premiumisation’ of the leading brands and the packaging upgrade of local producers 
  • A growing demand for aluminium closures especially in Latin America and Eastern Europe market replacing the short standard plastic cap 
  • A flexible solution and a first level of protection against the growing counterfeiting issues for spirits, premium olive oil and bottled water

Gobal Wine Closure Market share

The phenomenal increase in the use of aluminium closures for wine in the last 15 years 15 years (400 million to almost 9 billion pieces) bears witness to the fact that wine makers around the world are more and more convinced of their benefits,

  • A dominant market share in New Zealand (95%) and Australia (98%)
  • More than 60% market share in South Africa and Chile
  • A tremendous growth in Europe (2006-2016): especially in UK (almost 60%) and in Germany (more than 140%)
  • Continuous growth in North America

In addition to the almost 35 billion aluminium closures used to protect alcoholic beverages, several billion more safely seal water and olive oil on glass and PET bottles across the World.
