My little forum on bio bag for dogs
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. Tetrawedge which was wedge shaped packaging and tetraprisma which was a round octagonal packaging along with tetrafino which was a pouch shaped packaging were other cartons that were launched.
