Tetra Pak's commercial break-through did not arrive until the mid-60s with the new Tetra Brik package, introduced in 1963, and the development of Aseptic technology. 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. 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.
