The Quadro big bag is a ready-to-use, form-stable big bag (105x105x120cm, SWL 1200kg), with a liner that is made from a 7-layers, 140 micron, high-barrier film. The liner is equipped with a filling and a discharge spout, as well as the vQm high speed valve. The vacuum-proof liner of the Quadro bag has diagonal baffles, which are sealed across the four corners. This ensures that the big bag keeps its square shape after filling. The Quadro bags optimize the use of space & loading capacity throughout supply chain. If the bags are not under vacuum, they can be double stacked after filling to fit in a standard container.
