Vacuum packaging technology originated in the 1940s. Since polyester and polyethylene plastic films were successfully used in product packaging in 1950, vacuum packaging machines have developed rapidly, and their technical development trends are mainly reflected in the four aspects of high productivity, automation, single-machine multi-function, and the adoption of related new technologies. aspect. 1. Automation.
The automatic vacuum packaging machine has the functions of vacuuming, sealing, printing, and cooling at one time. It is mainly used for the packaging of tea, peanuts, shrimps, corn and other foods. 2. High productivity. The productivity of the vacuum packaging machine has grown from several pieces per minute to several 10 pieces, and the productivity of the thermoforming-filling-sealing machine can reach more than 500 pieces/minute.
3. Single machine with multiple functions. Multi-functions can be realized on a single machine, which can easily expand the scope of use. To realize the multi-function of a single machine, a 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. Select relevant new skills. In terms of packaging methods, inflatable packaging is used instead of 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 microelectronic technology are used; in sealing. Heat pipe and cold sealing technology, and advanced devices can also be installed directly on the vacuum packaging machine, such as a high-precision combination scale for coarse-grained materials controlled by a computer; on a rotary or vacuum packaging machine, use advanced high-speed arc surface cam indexing machinery etc.
