International vacuum packaging technology development trend

At present, the development trend of international vacuum packaging technology is mainly reflected in the following aspects:

The production efficiency of high-productivity vacuum packaging machines has grown from several parts per minute to dozens of pieces, and the production of thermoforming-filling-sealing machines can reach 500 pieces/minute or more.

The TYP-B series rotary vacuum chamber packaging machine produced by a Japanese company automated has a multi-station with a relatively high degree of automation. The machine has two turrets for filling and evacuation. The filling turret has six stations. The bag is filled, fed, filled and pre-sealed until the package is sent to the vacuum turret. The vacuum rotary table has 12 stations, that is, 12 vacuum chambers. Vacuum pumping and sealing are completed until the output of the finished product. The production efficiency can reach 40 bags/min. It is mainly used for packaging soft canned foods.

Stand-alone multi-function Multi-function on a single machine can easily expand the scope of use. To achieve stand-alone multi-function must adopt a modular design, through the transformation and combination of functional modules, become suitable for different packaging materials, packaging items, packaging requirements of different types of vacuum packaging machine. The representative product is a multi-station bag vacuum packaging machine manufactured by the HESSER factory of the German BOSCH company. Its functions of bag making, weighing, vacuum filling and sealing can be completed on a single machine.

When more and more functions are required to compose a production line, concentrating all the functions on a single machine will make the structure very complicated and the operation and maintenance will be inconvenient. At this time, several types of machines with different functions and efficiencies can be combined into more complete production lines. For example, the fresh fish developed by French CRACE-CRYOYA and ISTM, the vacuum packaging production line, and the textile vacuum packaging system developed by Sweden Shuhong International Co., Ltd. and the Swedish Textile Research Institute.

Relevant new technologies have been used to replace the vacuum packaging with inflatable packaging in a large number of packaging methods, and the three aspects of the inflatable body composition, packaging material and inflatable packaging machine have been closely combined. In control technology, more computer technology and microelectronics technology are applied.
