Bio bag, a review of the basics
The tetraclassic packaging was launched in nineteen fifty three by the founder Ruben Rausing, who had been working on it since nineteen 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. These initial cartons were tetrahedra, leading to the company's name: TetraPak, derived from "four" in the Greek languageIn 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. Some other tetra bio bags include tetrarex(gable top), tetratop(paper and plastic moulded in one) and the now discontinued tetraking.
