Plastic vacuum packing is used widely to promote the development of plastic vacuum packing machine, but also put forward higher requirements for its. Current international vacuum packaging technology and Equipments trend is mainly reflected in the following areas. A. Production Automation: vacuum packaging machine automation not only improves productivity, but also health and safety advantages. Japanese companies produced typ-b series rotary vacuum chamber packaging machines, is a very high degree of automation, multi-site packaging machine. The machine has two filling and vacuum turntable, filling a six-station rotary table, complete for the bags, feeding, pre-injection fluid sealing and vacuum package sent to the turntable; vacuum with 12-station rotary table (vacuum room), complete vacuum and sealing, product output, and other processes, the production efficiency of up to 40 bags / min, mainly for packaging of soft canned food. II. The introduction of new technology: in the packaging method, replace the extensive use of inflatable packaging vacuum packaging, the inflation component, packaging material and the inflatable packer of three closely integrated; in control technology, increased use of computer technology and microelectronics; in sealing, the application of heat pipes and cold sealing technology; the advanced device directly installed in the vacuum packaging machine, such as the installed high-precision computer-controlled combination of coarse-grained material balance; in the rotation or vacuum packaging machine, the application circular surface of advanced high-speed cam machinery. All of these new technologies, making the vacuum packaging machine is more efficient and intelligent. III. Standalone function: to achieve the single multi-function, can easily expand the scope of use. The multifunctional stand-alone modular design is done. Transformation by different functional modules and combined to produce for different packaging materials, packaging mouth, vacuum packaging machine packaging requirements. Representative products are company owned hesser German bosch multi-site plant bag vacuum packaging machine, can be set bag, weighing, filling, vacuum, sealing and other functions into one convenient and quick. IV. Group with production line: When you need to become more functional for a long time, all of the features in one single machine will become very complex structure, operation and maintenance is not easy. Then the function can be different to match the efficiency of a successful combination of several machines can be more complete production lines, to complete the more complex packaging process. Companies such as France cracecryoya and istm fish developed vacuum packaging production line, Sweden and the Swedish International Limited, Hong tree developed by the Institute of textile and textile vacuum packaging system models belong to this type.
