With the improvement of people's living standards, the requirements for packaging are also increasingly high. China's packaging machinery after more than 20 years of development, has become one of the top ten industries in the machinery industry, for the rapid development of China's packaging industry to provide an effective guarantee that some domestic packaging machinery to fill the domestic blank, some products and exports.

　　However, it should be recognized that the overall level of China's packaging machinery industry is still at a relatively low stage. At present, China's domestic packaging machinery exports are still less than 5% of the total output value, imports are roughly equivalent to the total output value, and developed countries are far away, some of the high content of packaging equipment still rely on foreign imports to meet domestic demand. This phenomenon of over-reliance on foreign products has seriously restricted the sustainable and stable development of China's packaging industry. The current competition in the industry is mainly reflected in the following aspects:

　　① R & D capability: domestic packaging industry enterprises are many, but their own R & D capabilities are weak, and insufficient investment. Industry who has strong R & D capabilities, and constantly new products, who will be able to occupy the market.

　　② manufacturing capacity: specialized production has become the trend. International packaging machinery manufacturers attach great importance to the packaging machinery and the entire packaging system general ability, which requires manufacturers to adjust their production capacity in a timely manner, to strengthen the specialized and systematic production capacity.

　　③ marketing capabilities: the packaging industry covers a very wide range, which requires manufacturers to determine how to segment the industry, how to stand out in a particular industry.

　　In the process of packaging machinery manufacturing, often applied to the integration of technology. As the packaging industry involves a wide range, and more types of equipment, making different manufacturers of PLC interface docking, equipment and coding machines, equipment and industrial control machines, information and equipment between the transmission method, etc., in the use of more or less in the process there are some problems, which requires manufacturers to consider how to integrate future automation control in communication, information, how to achieve with simple hardware and software. The hot spot of concern is: what automation manufacturers to the platform, different products to what standard to dock, etc..

　　When it comes to the packaging machinery manufacturing process, it is impossible not to mention MES (Manufacturing Execution System). the initial concept of MES is very good, to provide managers with the implementation of the plan, tracking and the current status of all resources, equipment. In the past few years, the application of MES seems to have entered a bottleneck, and the current bottleneck is how to implement and achieve the best state. Ltd. to implement tobacco business projects, the customer applied to MES, but in the implementation process, will encounter a variety of problems, such as how to optimize the entire workshop manufacturing process, whether the optimized process is reasonable, whether the product can be traced according to the bar code production process, error links and how to make mistakes; when the tobacco sorting process in the same production line need to mix the production of nearly When the same production line needs to mix and produce nearly 100 different types of cigarettes, how to automatically check the errors in the production process, etc.

　　In comparison, system integration technology is much more complex than industrial control automation technology. System integration technology is a structured integrated wiring system and computer network technology to integrate each separate equipment (or multiple manufacturers' equipment), functions and information into an interrelated, unified and coordinated system, so that resources can be fully shared and centralized, efficient and convenient management can be achieved. The key to system integration is to solve the problem of interconnection and interoperability between systems, which is a multi-vendor, multi-protocol and application-oriented architecture. This needs to solve all kinds of equipment, subsystem interfaces, protocols, system platforms, application software and other integration-oriented issues related to subsystems, organizational management and staffing, such as how to dock the PLC interfaces of different manufacturers' equipment, how to dock the docking interfaces between sorting and packaging equipment and coding equipment, and other issues.

　　If the industrial equipment control system adopts the same brand of PLC, it can ensure that the interface, protocol and data exchange between the main equipment and each sub-equipment can reach unimpeded, ensuring that no data loss, signal interference and other problems occur during the production process, so as to achieve high efficiency and accuracy of the production process. If different PLC brands are used, there is a lack of openness, and different manufacturers have their own different standards and platforms, increasing the difficulty of interfacing between different PLCs.

　　The higher the system integration requirements, the higher the industrial automation requirements. System integrators face further challenges in the future for: how to unite all the devices together, and the whole system low cost, high efficiency, stable performance, and scalability and maintainability. In addition, it also involves how to apply automatic identification technology, voice recognition technology, RFID technology to packaging manufacturing industry in the future, and how to use these technologies well and other issues. Internet of things is a more popular topic in China, the future of the packaging manufacturing industry will be more often introduced into the Internet of things technology, which requires more consistent standards between different products of different manufacturers, in order to achieve centralized, efficient and convenient management.
