The Development Trend Of Vacuum Packaging And Sealing Machine


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.

1. 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.

2. Automation. For example, Zhengzhou Xinghuo 500 double-chamber vacuum packaging machine has the functions of vacuuming, sealing, printing and cooling, and is mainly used for packaging foods such as tea, peanuts, shrimps and corn.

3, single machine multi-function. 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 are mandrel wheel multi-station bag vacuum packaging machine produced by HESSER factory of Germany BOSCH company. Its functions such as bag making, weighing, filling, vacuuming and sealing can be completed on a single machine. .

4. Form the production line. When more and more functions are needed, concentrating all the functions on one single machine will make the structure very complicated and the operation and maintenance are not convenient. At this time, several machines with different functions and matching efficiency can be combined into more complete functions. production line.

5. 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 of coarse-grained materials; on the rotary or vacuum packaging machine, advanced high-speed circular cam indexing Machinery, etc.
