At present, China's food packaging business most small-scale, & rsquo; small but complete & rsquo; is one of its main features, but there is a requirement regardless of the development of the industry, who repeated low production costs, the level of technology is relatively backward, easy manufacture of mechanical products, the industry currently has about a quarter of the companies producing low-level repetitive phenomenon exists. This is a great waste of resources, resulting in packaging machinery market confusion, hinder the development of the industry.
Most enterprises annual output value of between several hundred million to 10 million yuan, less than 100 million yuan of business has a lot number. Each year, nearly 15% of the conversion or closure of business, but there are 15% of companies have joined the industry, is extremely unstable phenomenon hinders the stability of the development of the industry.

With the continuous development of science and technology, a variety of food, the emergence of aquatic products, food packaging technology and equipment have put forward new demands. Currently, food packaging machinery increased competition, the future of food packaging machinery will be coordinated with industry automation, improve the overall level of packaging equipment to promote the development of multi-function, high efficiency, low consumption of food packaging equipment. Mechatronics achieve food packaging machinery packaging machinery to use more traditional mechanical control, such as the distribution cam shaft, and later appeared photoelectric control, pneumatic control, and other forms of control. However, with the increasing food processing technology, packaging parameter requirements continue to increase, the original control system has been difficult to meet the needs of the development of new technologies should be used to change the face of food packaging machinery. Today's food packaging machinery is a mechanical, electrical, gas, light, magnetism in one of the machinery and electronic equipment, in the design should focus on improving the automation of packaging machinery, packaging machinery research and development combined with the computer, mechanical and electrical integration control. Mechatronics is the essence from the system point of view, the use of process control theory, mechanical, electronics and information, testing and other related technologies organic combination, to achieve overall optimization.

Overall speaking, it is the computer technology into packaging machinery, mechatronics technology, the development of intelligent packaging technology, packaging technology requirements by product automatically combined into fully automatic packaging system for production, testing and production process control, fault diagnostics and troubleshooting will achieve fully automated, high-speed, high-quality, low consumption and production safety. Can be used for precise measurement of aquatic processed foods, high-speed filling and packaging process control, etc., will make packaging machinery structure greatly simplify and improve the quality of packaging products. If the most common plastic bag sealing machine, sealing quality and packaging materials, sealing temperature and speed and so on. Such as material (material, thickness) changes, temperature and speed have to change, but the number of difficult to grasp. Such as the use of computer control, the optimal parameters sealing temperature and speed to match a variety of packaging materials enter the computer memory, matched with the necessary sensors, automatic tracking system, so that no matter what changes in process parameters, can guarantee the best sealing quality.
