Analysis on the development trend of international vacuum packaging technology and equipment

at present, the development trend of international vacuum packaging technology and equipment is mainly reflected in four aspects, which also subvert the industrial development mode, namely, production automation, adoption of new technology, single machine multi-function and assembly production line. The following is a specific explanation from these four aspects, compared with PLLA

1. Production automation: the automation of vacuum packaging machine not only improves the production efficiency, but also has the advantages of safety and health

typ-b series rotary vacuum chamber packaging machine produced by Japanese company is a kind of packaging machine with a high degree of automation. The new capacity in the next two years is mainly box board paper Station packaging machine. The machine has two turntables for filling and vacuum pumping, and the filling turntable has six stations to complete bag supply, feeding, liquid injection and pre sealing, and send the packages to the vacuum pumping turntable; The vacuum turntable has 12 stations (vacuum chamber) to complete vacuum pumping, sealing, finished product output and other processes. The production efficiency can reach 40 bags/minute. It is mainly used for packaging soft canned food

2. Adopt new technology: in terms of packaging methods, a large number of inflatable packaging are used to replace vacuum packaging, and the research of inflatable components, packaging materials and inflatable packaging machines are closely combined; In terms of control technology, computer technology and microelectronics technology are more applied; In sealing, heat pipe and cold sealing technology are applied; The advanced device is directly installed on the vacuum packaging machine, such as the computer-controlled high-precision combined scale for coarse particles; In rotary or vacuum packaging machines, advanced high-speed circular arc cam indexing machines are applied. Luo Baihui, Secretary General of the International Association of mold, hardware and plastic industry suppliers, said that the increasingly extensive application of plastic vacuum packaging has promoted the development of plastic vacuum packaging machines and put forward higher requirements for them. The adoption of all these new technologies will make vacuum packaging machines more efficient and intelligent

3. Single machine multi-function: realize multi-function on single machine, which can easily expand the scope of use

the multi-function of single machine is completed by modular design. Through the transformation and combination of different functional modules, vacuum packaging machines suitable for different tensile testing machines have been produced. Enterprises have set up after-sales service outlets overseas to meet the packaging materials, packaging ports and packaging requirements

representative products include the multi station bag making vacuum packaging machine produced by Hesser factory affiliated to Bosch Company in Germany, which can integrate bag making, weighing, filling, vacuum pumping, sealing and other functions, which is convenient and fast

4. Assembly and distribution production line: when more and more functions are required, 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 successfully combined into a more complete production line to complete more complex packaging processes

the vacuum packaging production line for fresh fish developed by French cracecryoya and ISTM, and the textile vacuum packaging system developed by Swedish Shuhong International Co., Ltd. and Swedish Textile Research Institute belong to this type
