Vacuum packaging machine trends in the 21st century
Vacuum packaging technology originated in the 20th century, 40 years. Since 1950, polyester, polyethylene plastic film packaging has been successfully applied to the vacuum packaging machine will be a rapid development, its technical development trend is mainly reflected in high productivity, automation, stand-alone multi-function, the composition of production lines, using new technologies related to these 5 categories.
1, high productivity. Vacuum packaging machine’s productivity has developed into several pieces per minute, the number 10, thermoforming – filling – sealing machine productivity up to 500 / min or more.
2, automation. Such as Zhengzhou Spark 500 pairs of chamber vacuum packaging machine with a vacuum, sealing, printing, cooling off the completion of the function, mainly used for tea, peanut, shrimp, corn and other food packaging.
3, stand-alone multi-functional. The stand-alone to achieve multi-functional, can be easily expand the scope of use. Multi-function must be used to achieve stand-alone modular design, through the transformation and combination of function modules, to be applied to different packaging materials, packaging materials, packaging requirements of the different types of vacuum packaging machine. Representative products are owned by BOSCH Germany HESSER plant in spindle wheel multi-station bag vacuum packing machine, its bag, weighing, filling, vacuuming, sealing and other features on a single machine to complete the .
4 to form a production line. When you need to become more functional for a long time, will all of the features will focus on a single machine on a very complex structure, operation and maintenance is not easy, when can the different functions, efficiency, matching the success of several machines can be a more complete portfolio of production lines.
5, using the relevant new technologies. Extensive use in packaging methods to replace the inflatable packaging vacuum packaging, the inflatable component, packaging materials and inflatable packaging machine to the study closely integrated; in control technology, greater use of computer technology and microelectronics technology; in the application of heat pipe sealing and cold sealing technology, an advanced device can also be directly installed in the vacuum packaging machine, such as the installation of a computer-controlled combination of coarse-grained materials, high-precision scales; in rotation or vacuum packaging machine, the application of advanced high-speed circular surface cam indexing machinery.
