[8][9] After a brief engagement at the privately owned Stockholms Enskilda Bank, Rausing was employed by Sveriges Litografiska Tryckerier, SLT (later renamed Esselte), a well-known printing company.
[10][11] Experiencing self-service grocery stores for the first time during his stay in America, Rausing realised that this system, yet unknown in Europe, was going to be part of a new way of retailing.
[16] At the time, non-carbonated drinks such as milk and juices were sold in heavy and cumbersome glass bottles and Rausing was determined to find a way of implementing the new, modern packaging technology, spending a lot of resources on developing new concepts.
[23] The late 1960s and the 1970s saw a global expansion of the company, much due to the new Tetra Brik Aseptic package, debuted in 1968, which opened up new markets in the developing world and sparked off a virtual explosion in sales.
[24] After 30 years, Rausing's venture was successful and Tetra Pak eventually became one of the leading food processing and packaging company in the world.
