Packaging
Food
Filling and closing machines
When bottling beverages, cosmetic or pharmaceutical products, the bottle is at first evacuated before being filled to make sure the product reaches the customer in good quality.
Machines used for applications in the food industry are, in most cases, made from stainless steel.

Food packaging
Air and the oxygen that air contains have harmful effects on the quality and durability of fresh food. For this reason many processes need evacuation. The classic vacuum application in this field is vacuum packaging. Before sealing, a vacuum pump evacuates the air out of the packet. Vacuum pumps are used in numerous packaging machines for industrial use, e.g. Chamber machines, Forming machines, Carousel machines and Tray sealing machines.

Modified atmosphere packaging (MAP)
The surrounding pressure exerts a mechanical influence on the product that can greatly alter the external shape. For this reason, the MAP process has been the method of choice in many application areas. In this process, products are packaged in modified atmosphere and the oxygen removed. The product is enclosed in a blister package, placed in the vacuum chamber and evacuated. The modified atmosphere is then injected and the blister package and food are sealed with a protective film. Using this method the food retains its original shape and meats present a suitably red appearance to customers, even after extended storage.

Rolling machines
•Packing material for the bottom lane is pulled of the roll.
•It is heated in the forming tool and formed into packaging moulds.
•The packaging moulds are filled in by hand or automatically.
•The top lane of the packing material covers the filled moulds.
•In the sealing tool the air is extracted and if necessary modified atmosphere admitted. After this the sealing occurs by heat and pressure.
•The packaging lane is cross cut.
•After long cutting the packages are ready for dispatch.

Non-food packaging
When packing products, prior to sealing a vacuum pump would be used to evacuate the air from the packaging. Correct packaging provides the best transportation protection and ensures that products such as electronic parts, pharmaceuticals, etc, can be shipped to the customer aseptically and free of dust.
