International expansion had begun in the 1960s, when the first production plant outside of Sweden was established in Mexico in 1960, soon to be followed by another in the United States in 1962. In 1962, the first Tetra Classic Aseptic machine outside of Europe was installed in Lebanon. The late-1960s and 1970s saw a global expansion of the company, mainly due to the new Tetra Brik Aseptic package, launched in 1969, which opened up new markets in the developing world and sparked an explosion in sales.
