Vacuum packaging technology originated in the 1940s. Since the successful application of polyester and polyethylene plastic films in commodity packaging in 1950, vacuum packaging machines have developed rapidly. Its technological development trend is mainly reflected in five aspects: high productivity, automation, single-machine multi-function, production line formation, and the use of relevant new technologies.
1. High productivity. The productivity of vacuum packaging machines has developed from a few pieces per minute to dozens of pieces, and the productivity of thermoforming-filling-sealing machines can reach more than 500 pieces per minute.
2. Automation. The fully automatic vacuum packaging machine has the functions of vacuuming, sealing, printing, and cooling in one go. It is mainly used for packaging foods such as tea, peanuts, shrimps, and corn.
3. Single-machine multi-function. Realizing multi-functions on a single machine can easily expand the scope of use. To achieve single-machine multi-functions, 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.
4. Production line formation. When more and more functions are needed, concentrating all functions on a single machine will make the structure very complicated and inconvenient to operate and maintain. At this time, several machines with different functions and matching efficiencies can be combined into a production line with more complete functions.
5. Adopt relevant new technologies. In terms of packaging methods, a large number of inflatable packaging are used to replace vacuum packaging, and the research on inflatable components, packaging materials and inflatable packaging machines is closely combined; in terms of control technology, more computer technology and microelectronics technology are applied; in terms of sealing, heat pipe and cold sealing technology are applied, and advanced devices can also be directly installed on vacuum packaging machines, such as computer-controlled high-precision combination scales for coarse particles; in rotary or vacuum packaging machines, advanced high-speed arc surface cam indexing machinery is applied.
