Fluidtainer EVOH Flexi tanks are constructed with one layer of 9mil thick EVOH (Ethylene-vinyl alcohol copolymer) LLDPE (Linear low-density polyethylene) together with 2 layers of 125 micron PE protected with a PP jacket. EVOH flexi tanks are suitable for the carriage of sensitive liquid like wine in bulk or transformer oil. The EVOH prevents oxidation of the liquid cargo acting as a oxygen and moisture barrier from the atmosphere.
