The GBK 220 packaging machine is ideal for whole and sliced bread (standing slices, toast bread, etc.). The principle of the vacuum slider developed by HARTMANN has optimally proven itself in practice. The sophisticated technology of these machines guarantees optimum packaging, venting and closing. The packages are closed with the proven closing unit, which is characterised by its reliability and long service life. By consistently separating the product work area from the mechanical drive, this generation of machines also meets cleanroom requirements.
