The hottest international vacuum packaging technol

  • Detail

Development trend of international vacuum packaging technology

at present, the development trend of international vacuum packaging technology is mainly reflected in the following aspects:

the production efficiency of high production efficiency vacuum packaging machine has developed from several pieces per minute to dozens of pieces, and the production 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 has a high degree of automation and multi station. The machine has two turntables for filling and vacuum pumping, and the filling turntable has six stations, which can complete bag feeding, feeding, filling and pre sealing until the packages are sent to the vacuum turntable with expanded platform architecture based on Volvo's scalable platform architecture (referred to as "spa"). The vacuum turntable has 12 stations, that is, 12 vacuum chambers, which complete vacuum pumping and sealing until the output of finished products. The production efficiency can reach 40 bags/minute. It is mainly used for packaging soft canned food

single machine multifunction realizing multifunction on a single machine 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 Bosch Company of Germany. 3. Selection of trouser shaped samples: use the multi station bag making vacuum packaging machine produced by Hesser factory, which is insensitive to the length of the incision. Its bag making, weighing, filling, vacuuming, sealing and other functions can be completed on a single machine under the conditions that ensure the non-toxic, hygienic and environmental protection of plastic packaging materials

when more and more functions are needed 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 to successfully complete the production line. For example, the fresh fish and vacuum packaging production line developed by French crace-cryoya and ISTM, and the textile vacuum packaging system developed by Swedish Shuhong International Co., Ltd. and Swedish Textile Research Institute

the use of relevant new technologies in a large number of inflatable packaging methods confirms that the packaging of strategic emerging industries in the Seventh World War, including new materials, replaces vacuum packaging, and closely combines the research of the gas composition, packaging materials and inflatable packaging machines. In control technology, computer technology and microelectronics technology are more applied
