Maximize your production output with Vacuum by Busch.
Vacuum packaging. A packaging process in which air is extracted from the package prior to sealing.
The use of vacuum was one of the most groundbreaking advances in the packaging industry. And Busch was pioneer in this field.
In 1963, Dr Karl Busch developed the first vacuum pump to be used for vacuum packaging of foodstuffs, our rotary vane vacuum pump HUCKEPACK. With the follow-up product, the R5, we revolutionized food packaging.
Today, Busch is the market leader and industry standard for vacuum packaging. With our energy-efficient solutions, you can improve your packaging process, increase quality and maximize your output. Day by day millions of our vacuum pumps prove their robustness and reliability in packaging applications around the world.
Intelligent use of vacuum for food packagingFeinkost Dittmann, a German delicatessen manufacturer, has installed a Busch vacuum system for its packaging machines.
Half the vacuum pumps supply the base load in permanent operation at their optimum point of efficiency. The other vacuum pumps are frequency-controlled to respond to demand fluctuations.
Busch Vacuum Control ensures fine tuning of the pumping speed to match current demand. Energy consumption has been reduced by more than 70% compared to simple on/off operation mode.
How does vacuum packaging of foodstuffs work?
Vacuum helps to keep food fresh for a long time. With no loss in quality. Depending on the type of food to be packaged as well as the corresponding requirements, there are several possible processes. Ranging from chamber packaging, thermoforming packaging, or
clipped packaging to
Every vacuum packaging process starts with placing the products in a packaging. Either inside a bag, between an upper and a lower foil, or into a tray. The air, and thus the oxygen, is then evacuated from the packaging before it is sealed. This ensures an extended shelf life of the packaged product due to a reduced growth of oxygen-dependent bacteria. Furthermore, the taste, smell and appearance of the packaged products are preserved. And drying of the foodstuffs caused by evaporation is reduced.
Chamber packagingChamber packaging machines are in use for packaging with bags and foils.
Tabletop chamber packaging machines are mainly used by supermarkets, restaurants, hotels, or caterers. They are perfectly suited for vacuum packaging of small goods.
When it comes to vacuum packaging of medium size products, free-standing chamber packaging machines are the installation of choice.
For industrial vacuum packaging of large-format products double chamber packaging machines, conveyor belt packaging machines and rotary chamber packaging machines are used. These types of packaging machines are mainly installed in slaughterhouses, abattoirs, meat processing plants or cheese factories.
Tray sealersTray sealers work with prefabricated trays that are sealed with foils or additional plastic lids.
Thermoforming packagingThermoforming packaging machines also play an important role in packaging of foodstuffs. This process involves forming a tray by heating the lower foil in the packaging machine that is then automatically transported to the packaging chamber. Products can also be packaged in a tubular bag using tubular bag packaging machines. In these machines, the foil is welded into a tube and then sealed on both sides.
Modified atmosphere packaging (MAP)Particularly suitable for the packaging of sensitive fresh food products is the so-called modified atmosphere packaging (MAP). This technique consists of removing the air from the packaging and replacing it by a protective gas. Which allows for example to also reduce the pH value and thus increase the shelf life even further.
CENTRAL VACUUM SYSTEMS IN THE PACKAGING INDUSTRY
Removing the vacuum pumps from each packaging machine and installing a Busch central vacuum system resulted in a reduction in the total number of vacuum pumps. Moreover, waste heat could be removed from the packaging floor.
Block House now achieves annual savings in energy costs of over 8,000 Euro.
What are the benefits of central vacuum systems?
A central vacuum supply offers the potential to reduce operating costs and to increase energy efficiency.
Busch central vacuum systems are in operation throughout the world. In food packaging but also in many other industries.
We offer turnkey solutions tailored to individual process requirements. Including pipework and control installation, together with start-up service and training for the operating team.

Vacuum packaging in other industries
How does blister packaging work?
Vacuum can be used for thermoforming of plastic cavities or pockets for blister packaging. The packaging is usually sealed by a paperboard, a lidding seal made of aluminum foil or a printed plastic film allowing to display product information or branding.
Blister packaging has the advantage of exhibiting a product while simultaneously avoiding its contact with external factors such as humidity and contamination. Moreover, tampering of the packaged items can be prevented. If opaque blisters are used, the packaged product can also be protected against UV rays.
Blister packs are often used as unit-dose packaging for pharmaceuticals like tablets or capsules but also for small consumer goods or foodstuffs.
How does liquid packaging work?
Vacuum packaging is not limited to solids. Liquids such as oil, sauces, remoulades or dressings can also be packaged under vacuum.
The packaging of these goods presents special challenges. In order to avoid the leak of the liquids during the packaging process, the bags are positioned vertically or inclined inside the vacuum chamber. Moreover, liquid, or wet products carry the risk of boiling during vacuuming which needs to be prevented in order to avoid damage to the product.
How does currency packaging work?
Vacuum packaging is the most effective and reliable method of storing currencies.
Bundles of a predefined quantity of banknotes are vacuumized. The plastic packaging can then be printed with a seal of the relevant bank or branch and a specific identity code. This makes the transport and storage of the packages traceable and safe. Theft and fraud can be prevented because a manipulated package is easily recognizable by a broken seal and an increase of air inside the plastic bag.
Vacuum packaged, banknotes can be stored in a very compact way as the air is extracted and the volume of the package is thus reduced to a minimum. The packages therefore need less space and can be transported easily.
Moreover, vacuum packaging allows to protect currencies from the harmful influences of moisture or dirt.
