My little obsession on whisper bio bag
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. TetraPak also produced other non aseptic packaging systems . including tetrarex (gable top), tetratop (paper and plastic molded in one) and the now discontinued tetraking, these are some other tetra bio bags.
