International vacuum packaging technology and equipment development trend

The application of plastic vacuum packaging has become increasingly widespread, which has promoted the development of plastic vacuum packaging machines, and has also put forward higher requirements. At present, the development trend of vacuum packaging technology and equipment in the world is mainly reflected in the following aspects.

First, production automation: The automation of vacuum packaging machine not only improves the production efficiency, but also has the advantages of safety and health. The typ-b series rotary vacuum chamber packaging machine produced by the Japanese company is a multi-station packaging machine with a relatively high degree of automation. The machine has two turrets for filling and vacuuming. There are six stations for the filling turret, which completes bagging, feeding, and pre-sealing of liquids. The packages are sent to the vacuum turret; the vacuum turret has 12 stations (vacuum Room), to complete the vacuum pumping and sealing, finished product output and other processes, production efficiency up to 40 bags / min, mainly used for packaging soft canned foods.

Second, the use of new technologies: In the packaging method, a large number of inflatable packaging to replace the vacuum packaging, the inflatable components, packaging materials and inflatable packaging machine three closely integrated research; in control technology, more use of computer technology and micro Electronic technology; in the sealing, the application of heat pipe and cold sealing technology; advanced equipment installed directly on the vacuum packaging machine, such as loading a computer-controlled high-precision combination of coarse-grained scales; in the rotary or vacuum packaging machine, the use of advanced high-speed Circular cam indexing machines. The adoption of all these new technologies makes vacuum packaging machines more efficient and intelligent.

Third, stand-alone multi-function: In a single machine to achieve multi-function, can easily expand the scope of use. The multifunctionality of the single machine is accomplished using a modular design. Through the transformation and combination of different functional modules, vacuum packaging machines suitable for different packaging materials, packaging mouths and packaging requirements are produced. The representative product is a multi-station bag vacuum packaging machine manufactured by Hesser, a subsidiary of Germany-based bosch company. It can be used for bagging, weighing, filling, vacuuming, and sealing. It is convenient and quick.

Fourth, the assembly line: When the need for more and more features, all the functions in a single machine will make the structure becomes very complicated, operation and maintenance is not easy. At this time, several types of machines with different functions and efficiencies can be combined into a fully functional production line to complete more complicated packaging processes. For example, the fresh fish vacuum packaging production line developed by cracecryoya and istm in France, and the textile vacuum packaging system developed by Sweden Shuhong International Co., Ltd. and Swedish Textile Research Institute belong to this type.
