Whisper bio bag, an in-depth review
The companies name: TetraPak, was derived from the fact that these cartons were tetrahedral from "four" in the Greek language. Another one called the TetraBrik was introduced in nineteen sixty three (1963), which was 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. Some other tetra bio bags include tetrarex(gable top), tetratop(paper and plastic moulded in one) and the now discontinued tetraking. The tin culture has been opposed by the introduction of tetra bio bags for vegetables.
