【正文】 s living standards improve, the prospects of food packaging machinery, packaging technology is very promising. In recent years, the state has increased the quality and safety of food and medicine supervision, the production of food processing and packaging technology have raised new demands. The number of foodproducing enterprises have invested packaging equipment for technological transformation and innovation of product。s 2021 import a nd export volume of $ 2,737,000,000, of which exports $ billion, pared to 1999 to improve %. Food (dairy products, cakes, meat, fruit) machine, oven, packaging, labeling machines, paper and plastic aluminum posite can production equipment and other machinery exports more varieties of export of machinery, food machinery, such as sugar, beverages packaging machines and other equipment have begun to plete sets of export. The current development of the packaging machine 31 The past decade, the international packaging industry attaches great importance to improve the general ability of packaging machinery and packaging systems and multifunction integration capabilities to provide timely and flexible response of the means of production for the market to develop the rapid diversification of modities. Based on reasonable actual need to simplify the method of packaging and advantages of the packaging process, continuing to explore, significantly accelerated the pace of technological innovation. In particular, the simultaneous development of modern automatic machine echoes gradually clear. To build a diverse, universal, multifunction integrated packaging machinery system, we must first focus on solving the big problem of the bination and the mechanical and electrical integration, no doubt, this is an important development in the future direction. With the prosperity of China39。 The bulk of individual or collective, flake, bars and similar spherical domelike solid foods, Common larger plastic boxes, metal cans, posites produced by the bag, games cartridges. In short, sales of food packaging, metal, glass bottles, cans, boxes and other smaller share. There gradually declining trend, largely for gift packaging or special packaging. To the production of thin cardboard boxes, such as disk barrier performance is poor, mostly for the general over pack. Only the basis of posite materials to produce plastic film bags, 29 boxes, cups and other significant large enough to protect food beautifying the unique role and shape varied, easy processing, saving resources, the cost is not high, the use of light, strong adaptability. Is almost inclusive (usually with the exception of gasliquid materials) everything (extended to air all occasions) very promising. Particularly within the over pack, which bined with the package more effectively promote the wider use of packaged foods. With the accelerated pace of day to day work, nutrition and health foods rich and the enhancement of the sense of environmental protection. And the future of food packaging will also put forward many new requirements. Now attention is given refrigerators, microwave ovens rapidly growing popularity, coupled with other conditions related to the gradual maturity, not a long time. Development of quickfrozen food can be as convenient food, fast foods and access to family enterprises (including services, tourism sectors). Meanwhile conditions should vigorously develop the vacuum packaging, vacuum packaging and aseptic packaging aeration and other new technology, new products, so quickfrozen and packaged anic and jointly promote food packaging anization. As a result, the various levels of consumer hope on a small bag of food packaging boxes as the mainstay. Light on a prehensive understanding of the particular issues, mainly referring to the packaging easy to open, freeup time can be closed after revenue, safe and reliable. Therefore, we must adopt appropriate measures to further improve the type bag, seal and boxtype structure and the achievement of the main scientific and diversification. It has been recognized that the mercial petition and cheap tourists always should effectively do this, it is easy to capture the market, invincible. One effective way to achieve a reasonable package and simplified packaging is the dialectical unity. The reasons are obvious. Reasonable contains simplified, but simplification is not necessarily reasonable (as in the past to be eliminated nude thin plastic beverage packaging. soft earth covered biscuits carton packaging). In fact, from the mainstream, and quite a number of welldesigned pop on the bag and box packaging occupies a dominant position in this respect. Because after a reasonable form and structure to simplify the packaging and related technology and equipment. Can greatly reduce the expenditure and waste production and marketing process, and eliminate the many unstable factors, thereby improving the overall body School Official Cites Use of efficiency and ultimately the general direction of modern packaging. After thorough inspection is necessary, how to choose appropriate methods and packaging machinery types of packaging technology, to one or more selected materials packed in packaging material, packaging, so that the overall package to achieve optimal 30 function. Sales of food packaging still on the run, the most monly be used today, there are two basic methods of packaging technology. That the filling and wrap. Filling method applies in almost all types of packaging materials and containers. Specifically, the liquidity in liquid, powder, granular, mainly is relying on its own gravity. Will be supplemented, where necessary, the role of the mechanical pletion of the packaging process. Viscous semi fluid stronger shape of the larger single or bination of conditions would adopt
