Bio bag for dogs, something to read about
The first ones was launched in nineteen fifty three (1953) called the tetraclassic which the founder Ruben Rausing had been working on since ninieteen forty three (1943). This carton had the ability to be completely airtight which was accomplished by using a system of plastic and aluminum coated paperboard combined with an aseptic filling system. The companies name: TetraPak, was derived from the fact that these cartons were tetrahedral from "four" in the Greek language. In nineteen sixty three (1963) the company introduced another one called TetraBrik, a rectangular cuboid carton. Later, more cartons were launched such as the tetrawedge which was wedge shaped and tetraprisma which was round octagonal and then there was the tetrafino which was a pouch shaped packaging.
