Vacuum packaging technology originated in the 1940s. Since the polyester and polyethylene plastic film was successfully applied to commodity packaging in 1950, the vacuum packaging machine has been rapidly developed. Its technological development trend is mainly reflected in high productivity, automation, single machine multifunction, component production line, and adoption of related new technologies. These five aspects.
High productivity. The productivity of vacuum packaging machines has grown from a few pieces per minute to a few 10 pieces, and the productivity of thermoforming-fill-sealing machines can reach more than 500 pieces per minute.
automation. For example, the TYP-B2 series rotary vacuum chamber packaging machine of Toyo Automa Co., Ltd. of Japan is a multi-station packaging machine with a relatively high degree of automation. The machine has two turntables for filling and vacuuming, and there are 6 stations for filling the turntable, and the bag is filled, fed, and pre-sealed until the package is transferred to the vacuum turntable. The vacuum turret has 12 stations, that is, 12 vacuum chambers, which complete vacuuming and sealing until the finished product is output, and the productivity can reach 40 bags/min, which is mainly used for packaging soft cans.
Single machine multifunction. Multi-function on a single machine, you can easily expand the scope of use. The realization of single-machine multi-function must adopt modular design, and through the transformation and combination of functional modules, it becomes a different type of vacuum packaging machine suitable for different packaging materials, packaging articles and packaging requirements. The representative products include multi-station bag vacuum packaging machine produced by HESSER factory of Germany BOSCH Company. The functions of bag making, weighing, filling, vacuuming and sealing can be completed on one single machine.
Form the production line. When more and more functions are needed, 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 machines with different functions and matching efficiency can be combined into more complete functions. production line. For example, the fresh fish vacuum packaging production line developed by CRACECRYOYA and ISTM in France, the textile vacuum packaging system developed by Swedish Tree Hong International Co., Ltd. and the Swedish Textile Research Institute.
Adopt relevant new technologies. In the packaging method, a large number of inflatable packaging is used instead of vacuum packaging, and the research on inflatable components, packaging materials and inflatable packaging machine is closely combined; in the control technology, more computer technology and microelectronic technology are applied; in sealing application Heat pipe and cold sealing technology can also be installed on the vacuum packaging machine directly, such as computer-controlled high-precision combination scale of coarse-grained materials; on the rotary or vacuum packaging machine, advanced high-speed circular arc cam indexing Machinery, etc.
