A multi-national food packaging and processing company with head offices in the southern Swedish city of Lund, Tetra Pak offers packaging solutions, filling machines and processing solutions for dairy, beverages, cheese, ice-cream and other prepared food.

It was founded by Ruben Rausing (1895-1983) in 1951 as a subsidiary to Ĺkerlund & Rausing and built on an innovation by Erik Wallenberg, the tetrahedron package, from which the company name was derived. Then, on April 14, 1954, the first machine producing 500 ml milk packages were sold to a Stockholm dairy. Later that same year, the first machine was exported to Germany, followed by France and other countries.
