Where can vacuum be used in packaging processes?
Vacuum frequently plays an essential role in packaging processes, and in the production of packaging. Packaging can be efficiently and precisely formed, thermoformed and coated using vacuum techniques. It can also be moved, transported, opened and sealed by vacuum. During the packaging process, goods to be packaged can be fed and inserted with the aid of vacuum.
Using vacuum in food packaging helps to keep food fresh for longer – with no loss in quality. The use of MAP (modified atmosphere packaging) for fresh food products maintains the appearance, freshness and flavour.
Which Busch vacuum solutions are especially suitable for packaging applications?
R 5 series vacuum pumps are the ideal vacuum generators for packaging. They use the proven rotary vane principle and are regarded as the "packaging vacuum pump par excellence".
We also offer oil-free technology for a wide range of packaging applications – such as the highly energy-efficient Mink claw vacuum pumps and the dry running rotary vane vacuum pumps of the Seco series. For example, Mink vacuum pumps are used to transport the foil which creates the tubular bag during the packaging process, whereas Seco vacuum pumps are primarily used in handling or holding processes.
