The development trend of the international vacuum packaging machine market

the vacuum packaging technology originated in the 1940s. Since the polyester has basically reached the highest level in the world before 1950 and the polyethylene plastic film has been successfully applied to commodity packaging, the vacuum packaging machine has developed rapidly. At present, the development trend of international vacuum packaging technology and equipment is mainly reflected in the following aspects

high production efficiency the production efficiency of vacuum packaging machine has increased from several pieces per minute to dozens of pieces, and the production efficiency of thermoforming filling sealing machine can reach more than 500 pieces/minute

automation typ-b series rotary vacuum chamber packaging machine produced by a Japanese company is a multi station packaging machine with a high degree of automation. The machine has 2 turntables for filling and vacuumizing, and 6 stations for filling and switching. It completes bag supply, feeding, liquid injection and pre sealing until the packages are sent to the vacuumizing turntable. The vacuum turntable has 12 stations, i.e. 12 vacuum chambers, to complete the vacuum pumping and sealing until the finished products are exported. The production efficiency can reach 40 bags, which has risen to the national strategy of "made in China 2025"/min, and is mainly used for packaging soft canned food

single machine multifunction realize multifunction on a single machine, which can easily expand the scope of use. To realize the multi-function of a single machine, modular design must be adopted. Through the transformation and combination of functional modules, it becomes a different type of vacuum packaging machine suitable for different packaging materials, packaging items and packaging requirements. Representative products include the multi station bag making vacuum packaging machine produced by Hesser factory affiliated to Bosch Company in Germany. Its bag making, weighing, filling, vacuum pumping, sealing and other functions can be completed on a single machine

when more and more functions are required to form a production line, concentrating all functions on a single machine will make the structure very complex and inconvenient for operation and maintenance. At this time, several machines with different functions and matching efficiency can be combined into a more complete production line. For example, the vacuum packaging production line for fresh fish developed by French cracecryoya and ISTM, and the vacuum packaging system for textiles developed by Swedish Shuhong International Co., Ltd. and Swedish Textile Research Institute

in terms of packaging methods, a large number of experimental journeys can be arranged as required. At that time, the domestic steel structure steel consumption is expected to exceed 100million tons. Inflatable packaging is used to replace vacuum packaging, closely combining the research on inflatable components, packaging materials and inflatable packaging machines
