F inn Rausing is a Swedish billionaire and an heir to the Tetra Laval fortune, one of the world's most significant and private business empires.

The group includes three main divisions: Tetra Pak (liquid food packaging), DeLaval (dairy farm equipment), and Sidel (beverage bottling and packaging equipment). Finn serves on the board of the privately held company, helping to steward the massive and highly profitable global enterprise. The family is known for being extremely private and for its successful long-term management of one of the world's most important packaging companies.
