Vacuum packaging machinery points

Vacuum packaging is the packaging that protects the product from environmental pollution and prolongs the shelf life of food, which can increase the value and quality of the product. Vacuum packaging technology originated in the 1940s. Since the polyester and polyethylene plastic films were successfully used in commercial packaging in 1950, vacuum packaging machines have been rapidly developed.

In the fields of people's lives and work, various kinds of plastic vacuum packaging abound. Lightweight, sealed, fresh-keeping, anti-corrosion, rust-proof plastic vacuum packaging covers everything from foods to pharmaceuticals and knitwear, from precision product manufacturing to metal processing plants and laboratories. The application of plastic vacuum packaging has become increasingly widespread, which has promoted the development of plastic vacuum packaging machines, and has also put forward higher requirements.

High Efficiency: High Productivity The vacuum packaging machine's production efficiency has grown from several parts per minute to dozens of pieces, and the production of thermoforming-filling-sealing machines can reach more than 500 pieces/minute.

Automation: The TYP-B series rotary vacuum chamber packaging machine produced by a Japanese company has a multi-station with a relatively high degree of automation. The machine has two turrets for filling and evacuation. The filling turret has six stations. The bag is filled, fed, filled and pre-sealed until the package is sent to the vacuum turret. The vacuum rotary table has 12 stations, that is, 12 vacuum chambers. Vacuum pumping and sealing are completed until the output of the finished product. The production efficiency can reach 40 bags/min. It is mainly used for packaging soft canned foods.

Stand-alone multi-function: Multi-function on a single machine can easily expand the scope of use. To achieve stand-alone multi-function must adopt a modular design, through the transformation and combination of functional modules, become suitable for different packaging materials, packaging items, packaging requirements of different types of vacuum packaging machine.

Assembling Production Lines: As the production line becomes more and more functions are needed, concentrating all functions on a single machine will make the structure very complicated and the operation and maintenance will be inconvenient. At this time, several types of machines with different functions and efficiencies can be combined into more complete production lines.

Adopting new technologies: In terms of packaging methods, a large number of inflatable packagings are used instead of vacuum packaging, and the three aspects of inflatable components, packaging materials and pneumatic packaging machines are closely combined. In terms of control technology, more computer technologies and microelectronic technologies are used. Sealing, the application of heat pipe and cold sealing technology; advanced equipment installed directly on the vacuum packaging machine, such as loading a computer-controlled high-precision combination of coarse grain weigher; in the rotary or vacuum packaging machine, the application of advanced high-speed arc Surface cam indexing machines, etc. The adoption of all these new technologies makes vacuum packaging machines more efficient and intelligent.
