Vacuum packaging

Maximize your production output with Vacuum by Busch.

meat_vacuum_packed_1200x675_1

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.

“Busch is an active partner, acting quickly on our needs. Great partnership. “
Nilson Leopoldino, Maintenance Manager at JBS

Vacuum packaging in the food industry

feinkost_dittmann_fig1

Intelligent use of vacuum for food packaging

Feinkost 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 carousel packaging.

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 packaging

Chamber packaging machines are in use for packaging with bags and foils. Tray sealers work with prefabricated trays that are sealed with foils or additional plastic lids.

Our solutions

Thermoforming packaging

Thermoforming 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.

Our solutions

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

busch_centra_vacuum_system_stage
Block House Fleischerei, a German producer of portioned fresh meat products and burgers, analyzed the energy consumption of its packaging machines when it was being certified according to ISO 50001.
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.

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.
