Tetra Pak

Tetra Pak is a company name and brand — but in popular parlance it has become synonymous with paper packaging. The company´s first success was a tetrahedron, a pyramid with four sides, which was filled with milk.

The inventor, Erik Wallenberg, who came up with the idea in 1944 and the entrepreneur, Ruben Rausing, patented and launched Tetra Pak in 1951. The physicist, Niels Bohr, said that he “had never seen such a perfect practical application of a mathematical idea".

A tetrahedron can be folded using a single piece of paper. This makes them economically efficient to manufacture. If you roll a piece of paper into a tube, you can make the number of tetrahedrons you want.
In 2010 Tetra Pak sold 154 billion packages throughout the world. 31 billion are recycled into pizza boxes and juice cartons among other things.
