What I say on bio bag
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. 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. Recently, tetra bio bags have been introduced for vegetables opposing the tin culture. This new tetra bio bags, called tetrarecart are laminated paper boxes and allow for more subtle reprocessing of vegetables than canning permits.
