Tetra-Pak: How a carton took over the world The name of the company was derived from the tetrahedron-shaped packaging, which required minimal material with maximum hygiene. The first Tetra-Pak machine was delivered in 1952, which packaged cream in 100ml cartons. Milk packaging was not developed until 1954, when the first Tetra-Pak machine was exported to Hamburg. The company has now grown to be the largest food packaging company in the world by sales, with the company still being privately held and now known as Tetra Laval. In the Forbes ranking of the wealthiest people in the world, Hans Rausing, son of the company's founder, was ranked 83rd, with an estimated wealth of $10bn (£6.4bn) in 2011. In 2008, Hans Kristian Rausing, grandson of Ruben, and his American-born wife Eva, received a conditional caution after confessing that they were drug addicts. They had been charged with possession of a large amount of cocaine and smaller quantities of crack, heroin and cannabis after a Scotland Yard investigation
