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.


Forming

For vacuum forming, an additional pump is needed at that part of the machine.

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.

Production of PET containers

Vacuum technology is used for the following applications: pellet drying, pellet conveying, extruder degassing, injection molding of performs, preform removal and handling, preform drying, blow molding of bottles, plasma treatment to deposit a barrier layer, pneumatic conveying of bottles, filling, labeling, Packaging and palleting, recycling

Tray sealing

  • Generating a vacuum and sealing the bag or:
  • Feeding inert gas and sealing the bag

Trim removal

The film strips that are cut off are sucked into a container with our radial fan range CEVF. The collected film strips can be recycled.

Further applications

  • Pick + Place
  • Freeze drying
  • Soft ice dispensing

Packaging - Non-food


Air cushion machines

Film tubes are inflated with compressed air and welded together to form cushions. These cushions can be used as protective filling material.

Blister machines

Blister packaging is often vacuum generated.

Evacuation

When bottling beverages, cosmetic or pharmaceutical products, the bottle is evacuated before being filled to make sure the product reaches the customer in good quality.

Filling and closing units

Chamber machines

  • Generating a vacuum and sealing the bag
  • Feeding inert gas and then sealing the bag

Rolling machines

  • In the sealing tool the air is extracted and if necessary modified atmosphere admitted
  • Final step is sealing the recipient

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.


Production of paper bags

The L-Series is used for folding paper bags.

Reduction of transport volume

Vacuum packaging of clothes. The brand new clothes are shrink-wrapped to be able to charge trucks and containers to maximum capacity.

Tray sealing

  • Generating a vacuum and sealing the bag or
  • Feeding inert gas and sealing the bag afterwards

Trim removal

The film strips that are cut off are sucked into a container with our radial fan range CEVF. The collected film strips can be recycled.
