Vacuum packaging technology originated in the 1940s. Since 1950, polyester, polyethylene plastic film has been successfully applied to the product packaging, vacuum packaging machine developed rapidly.

The international vacuum packaging technology and equipment development trend mainly reflected in the five areas.

High production efficiency vacuum packaging machine production efficiency from the development of several pieces per minute to 10, thermoforming - Fill - Seal machine production efficiency of up to 500 pieces / min.

Automation, Japan produced TYP-B series rotary vacuum chamber packaging machines, multi-station is a high degree of automation of packaging machines. The machine has two filling and vacuum turntable, filling station turntable 6 to complete for the bags, material, liquid injection pre-sealed until the packages sent to the vacuum turntable. Vacuum turntable 12 station, which is 12 vacuum chamber, complete vacuum and sealed until the finished product output, the production efficiency of up to 40 bags / min, is mainly used for packaging soft canned food.

Stand-alone multi-function implemented on a single multi-function, can easily expand the scope. Achieve stand-alone multi-function must be modular in design, transformation and combination of functional modules, as applicable to different packaging materials, packaging materials, packaging requirements of different types of vacuum packaging machine. The representative products HESSER plant belongs Germany BOS CH station bag vacuum packing machines, bag, weighing, filling, pumping vacuum, sealing a variety of functions in a single.

Composition when the need rises, all concentrated in a single production line will make a very complex structure, operation and maintenance is not easy. Then the function can match the efficiency of the combination of several machines successfully complete production line. Such as France the CRACECRYOYA and ISTM developed the fish vacuum packaging production line, tree, Sweden Macro International Limited and the Swedish Textile Research Institute of Textiles vacuum packaging system.

The use of new technology in the packaging methods, extensive use of inflatable packaging to replace the vacuum packaging, the inflation component, packaging materials and the inflatable packaging machine three closely integrated. Control technology, increased use of computer technology and microelectronics technology. Sealed, the application of heat pipes and cold sealing technology, state-of-the-art device is installed directly on the vacuum packaging machine, such as wearing a the coarse material high-precision computer-controlled combination of scale. In rotation or vacuum packaging machine, the application of advanced high-speed circular surface cam machinery.
