           我国真空包装机械生产始于20世纪70年代，发展较快，从引进技术消化吸收入手，起点较高。经过30年的发展，现已能够生产多种型号的真空充气包装机过滤器。除新疆、西藏、青海等少数几个省区外，生产企业遍布全国各地，但其中以真空包装机作为主导产品的企业占少数，大部分是兼营的中、小型企业，不少企业的生产是以组装为主。我国产品现有品种比较齐全，基本上能满足市场的需要，主要品种有单室、双室、蝶阀输送带式、插管式、旋转真空室式、热成型、混合气体充气式等，以半自动操作为主，全自动连续式、疏水阀大真空室及适合液体包装的真空包装机较少。缺乏高效、专用的真空包装机。

　　我国真空充氮包装机大多是在消化吸收国外技术的眼镜阀基础上发展起来的，在设计、结构方面与国外同类机型相比差距不明显，但存在配件质量不过关等问题，使整机使用可靠性与国外同类机型还存在差距。

　　高新技术的应用带动真空充气包装机械在整体设计上不断改进。Ball Valves在充入混合气体方面和热管热封技术、高真空电磁阀等方面，发达国家已普遍采用高新技术，我国在这方面差距较为明显，还有待进一步发展，有些品种如行列式真空包装还待填补空白。

　　今后我国应不断跟踪国外真空包装机先进技术，加速高新技术的应用，填补空白品种，并重视元器件配件的生产，提高可靠性，扩大使用范围。

           Vacuum packaging machinery in China began in the 20th century 70s, developed rapidly, starting from the digestion and absorption of imported technology, high starting point. After 30 years of development, is now able to produce a variety of inflatable models of vacuum packagingBall Valves machine. In addition to Xinjiang, Tibet, Qinghai, a few provinces, the production companies throughout the country, but to the vacuum packaging machine as the main products of company are in the minority, the majority are soGate Valves engaged by the small and medium enterprises, many of the production is the main assembly. Present a relatively complete variety of our products can basically meet the needs of the market, the main varieties of single rooms, double rooms, conveyor type, tube type, rotary vacuum chamber, heat forming, hybrid gas inflatable, in order to semi-automatic the main operation, automaticButterfly Valves continuous, large vacuum chamber and suitable for liquid packaging, vacuum packaging machine less. Lack of efficient, dedicated vacuum packaging machine. Vacuum packaging machine in China are mostly nitrogen in the digestion and absorption of foreign technology, developed onCheck Valves the basis of, in the design, structural aspects of the gap with foreign similar models Xiangbi obvious, Dan Cunzaipeijian quality, but Guan combine to make machine Shiyongkekao nature and there is a gap similar foreign models. Application of high inflation driven vacuum packaging machinery in the overall design of continuous improvement. Mixed gases in the filled and heat pipe heat sealing technology, high-vacuum solenoid valve and so on, developed countries have generally used high technology, ChinaGlobe Valves is more obvious gaps in this regard remains to be further developed, and some species such as the determinant of vacuum packing is good enough to be filled blank. China in the future should continue to follow Guowai advanced technology of vacuum packaging machine, high speed application, fill the gap varieties, and emphasis on component parts of production, improve reliability, expand usage.
