China's vacuum packaging machinery production began in the 1970s, the rapid development, starting from the introduction of technology to digest and absorb, a higher starting point. After 30 years of development, it is now possible to produce a variety of models of vacuum inflatable packaging machine. Except for a few provinces and autonomous regions such as Xinjiang, Tibet and Qinghai, manufacturing enterprises are spread all over the country, but among them, a few are enterprises that take vacuum packaging machines as their leading products. Most of them are small and medium-sized enterprises concurrently and many enterprises produce It is based on the assembly. The existing varieties of our products are relatively complete, basically to meet the needs of the market, the main varieties of single room, double room, conveyor belt, intubation, rotary vacuum chamber, thermoforming, mixed gas inflatable, semi-automatic operation Mainly, automatic continuous, large vacuum chamber and less suitable for liquid packaging vacuum packing machine. Lack of efficient, dedicated vacuum packaging machine. Most of China's nitrogen-filled vacuum packaging machines are based on the digestion and absorption of foreign technology developed on the basis of the design, structure and foreign similar models compared to the gap is not obvious, but there is the quality of spare parts, but there are problems so that the whole machine is reliable Sex and foreign similar models there is still a gap. High-tech applications driven vacuum inflatable packaging machinery in the overall design of continuous improvement. In the mixed gas and heat pipe heat sealing technology, high vacuum solenoid valve, developed countries have generally adopted high-tech, our country in this area is more obvious gap, yet to be further developed, some varieties such as the ranks of vacuum packaging to be filled blank. In the future, China should continue to follow the advanced technology of foreign vacuum packaging machine, speed up the application of high technology, fill in the blank varieties, and attach importance to the production of components and parts to improve the reliability and expand the scope of use.
