The most popular packaging machinery industry in C

  • Detail

China's packaging machinery industry should accelerate its development

with the increasing development and expansion of China's economy, the packaging industry has also developed rapidly at an average annual rate of 18%. The total output value of the national packaging industry has increased from 7.2 billion yuan in 1980 to more than 230 billion yuan now, providing packaging for trillions of industrial and agricultural products and hundreds of billions of dollars of export commodities every year, which has played an important role in the development of the national economy

however, in the process of the rapid development of China's packaging industry, a large number of complete sets of equipment with high technical content still rely on imports. For example, plastic film biaxial stretching equipment, a production line of nearly 100million yuan, has been introduced since the 1970s. So far, 110 such production lines have been imported in China. There are also aseptic packaging boxes widely used in the dairy industry, and almost all filling equipment are provided by Tetra Pak in Sweden. The excessive dependence of China's packaging machinery on foreign high-end technology has become a hidden worry that seriously restricts the sustainable and stable development of China's packaging industry. Because the technical content of most packaging products is reflected in processing technology and technical equipment. Technology is the core, equipment is the key, and packaging equipment plays a leading role in packaging technology. Although the introduction of a large number of advanced equipment has greatly accelerated the development speed of China's packaging industry and narrowed the gap between China's packaging industry and developed countries, we can't rely on foreign high-end technology and technical equipment, and plastic laboratory machines can be conditioned at different speed levels. This is because foreign technical equipment is expensive, and some small and medium-sized enterprises are unable to introduce it, which is not conducive to the overall improvement of the technical level of China's packaging industry; It is not conducive to developing our own intellectual property rights and cultivating our own professional designers. In the long run, we can only follow others, which will lose the control of development and the initiative of the market. In view of the above reasons, and the packaging industry is a supporting industry, involving many fields of the national economy, especially the food industry and beverage industry, which depend on the technological progress and supporting services of the packaging industry. Therefore, we can no longer ignore the negative impact of the backward situation of packaging machinery on the overall development of China's packaging industry

In the 1980s, packaging machinery manufacturers in developed countries continued to apply new technologies in other fields (such as microelectronics, lasers, heat pipes, new materials, etc.) to the development of packaging machinery, creating a new situation for packaging machinery, making packaging machinery one of the fields attracting attention in the machinery industry

the United States has a long history of packaging machinery development, and has formed an independent and complete packaging machinery system, ranking first in the world in terms of variety and output. The products are mostly high, large, fine and sharp. Machinery and computer are closely combined to realize electromechanical integration

at present, Japan has become the world's second only to the United States in the production of packaging machinery. The manufacturing of packaging machinery in Japan is dominated by small and medium-sized enterprises. There are many varieties and specifications of packaging machinery, mainly small and medium-sized single machines, which have the advantages of small volume, high precision, easy installation, convenient operation and high degree of automation. Since 1990, technologies such as frequency conversion adjustment, photoelectric tracking, contactless electronic switch and dynamic data display have been applied to packaging machinery

Germany, Italy, Britain, Switzerland, France, etc. are all important countries producing packaging machinery in the world. A common feature of them is that the export proportion is very large. For example, the export share of Germany and Italy is nearly 80%, and that of Switzerland is more than 90%. German packaging machinery is in a leading position in measurement, manufacturing and technical performance, especially printing machinery, beer and beverage filling equipment. It has the characteristics of high speed, complete set, high degree of automation and strong reliability. German packaging machinery pays attention to flexibility and flexibility design, and now computer simulation technology is widely used. Italian packaging machinery is mostly used in the food industry, which has the characteristics of excellent performance, elegant appearance and low price

at present, countries all over the world attach great importance to the development of packaging machinery, and high-tech products integrating machinery, electricity, gas, light and magnetism continue to emerge. High efficiency of production, high utilization of resources, energy conservation of products, practicality of high-tech and commercialization of scientific research achievements have become the development trend of packaging machinery all over the world

China's packaging machinery started late, and developed slowly before the 1980s. It can only produce several low-level packaging machinery, and has not become an independent industry. There is no packaging machinery in the product catalogue published by the state

it also provides a reference for the future development direction of automobiles. After the reform and opening up, the social demand for packaging machinery is increasing. Coupled with the government's attention and support, China's packaging machinery has developed rapidly, with an average annual growth rate of more than 30%. In the 1990s, it is still growing at a rate of more than 20%. After more than 20 years of development, China's packaging machinery has become one of the top ten industries in the machinery industry, and has made remarkable achievements in both output and variety, providing a strong guarantee for the rapid development of China's packaging industry. Some packaging machines have filled the domestic gap and can basically meet the needs of the domestic market. Some products are still exported. In 2001, the national output of packaging machinery reached 533000 sets, with an output value of 19.55 billion yuan, accounting for 8.2% of the total output value of the national packaging industry. China has become one of the world's largest countries in the production and consumption of packaging machinery

however, there are still many problems in China's packaging machinery manufacturing industry. First, there is a lack of macro overall planning, and people often rush to invest in the development of new products, with low-level duplication. Second, there is a lack of capital investment. Due to insufficient funds, the investment within ± 0.1% of the set value of research and development accounts for less than 1% of the average level of sales. It is impossible to produce one generation, develop one generation, and research one generation. Due to the lack of technical reserves, the introduction of technology and the poor digestion and absorption work, the enterprise has few new products and lacks market competitiveness. Third, there is a lack of professional and technical personnel. Because the current profit level of the packaging industry is not high, it is difficult to attract excellent technical personnel, and the ability to independently develop products and innovate is weak, even the ability to digest and absorb similar foreign products is weak. At present, the export volume of China's packaging machinery is less than 5% of the total output value, but the import volume is roughly equivalent to the total output value

compared with developed countries, the gap in China's packaging machinery industry is mainly reflected in the following aspects: from the perspective of product structure, there are about 2300 kinds of foreign packaging machinery, there are many complete sets of equipment, and new technologies and products continue to appear. However, there are only more than 1300 kinds of packaging machinery in China, with a small number of supporting equipment, which is lack of high-precision and large-scale products, and can not meet the market demand; From the perspective of product quality, the gap is manifested in low product performance, poor stability and reliability, unsightly appearance, rough surface treatment, poor quality, short service life and low reliability of many acenaphthene components, which affect the quality of the overall product; From the perspective of enterprise conditions, foreign enterprises have large production scale and high degree of specialization. Most of them adopt cad/cam technology, and the technology, production, sales and other work of enterprises basically realize computer management. However, the domestic packaging machinery industry lacks leading enterprises, there are not many enterprises with large production scale and high-grade products, there are many enterprises manufacturing similar products, and there are generally weak technical force and low level of technical equipment; From the perspective of product development, China is still basically at the stage of testing and imitation, with weak self-development ability and lack of pilot bases for scientific research and production. Scientific research funds account for only 1% of sales, compared with 8% to 10% abroad

on the whole, the technical level of China's packaging machinery is 20 years behind that of advanced countries, and it is at a disadvantage in the competition of product development, performance, quality, reliability, service and so on

according to the prediction of relevant experts, the output of packaging machinery in China will increase to 670000 sets in 2005 and 930000 sets in 2010. However, the extensive operation of increasing capital investment and expanding production scale can no longer meet the needs of the development of the situation. China's packaging production has entered a new period of adjusting product structure and improving development capacity. Technology upgrading, product upgrading and business management are important topics for the development of the industry

in terms of product structure, we should be market-oriented, change the current situation of low-tech content and low-level competition, eliminate a number of low-efficiency, high consumption, low-grade, low value-added, labor-intensive products, and strive to develop and produce large complete sets of equipment and high-tech products with high efficiency, low consumption and the right production and marketing

in terms of packaging function, since the ultimate goal of packaging machinery is to complete product packaging and improve work efficiency, during the development period when industrial and agricultural products tend to be refined and diversified, packaging machinery products are required to develop in the direction of multi-function and single high-speed. For example, the packaging requirements of Coca Cola products are speed and quality, while the replacement of packaging structure is secondary; For candy packaging, pillow type, special-shaped and conjoined products are needed, and such products are required to complete the packaging of a series of products on a packaging machine

in terms of technical performance, advanced technologies in other fields should be applied to packaging machinery, such as electromechanical integration technology, heat pipe technology, remote control technology, automatic flexible compensation technology, etc., so as to greatly improve the technical performance of products

in terms of design ideas, the standardization and modularization of structural design are one mode. In this way, the original model can be used for modular design, so that the new model can be converted in a short time, which greatly improves the speed of product upgrading, and is also conducive to the professional production of packaging machinery

in manufacturing, specialized production has become a trend. International packaging machinery manufacturers attach great importance to the general ability of packaging machinery and the whole packaging system. Some general standard parts are no longer produced by packaging machinery factories, and some special parts are produced by highly specialized manufacturers. In a sense, the real packaging machinery factory is an assembly factory


strengthen macro guidance and industry coordination

according to the development of China's packaging industry, reasonably introduce advanced equipment and speed up the process of digestion and absorption. For the packaging machinery and equipment with large market demand and great technical difficulties, we should concentrate the advantageous forces of the industry, take the road of combining production, learning and research, carry out digestion and absorption and scientific research in an organized and targeted manner, develop packaging machinery with intellectual property rights, break foreign technological monopoly, and accelerate the improvement of China's packaging technical level and self-sufficiency

the state gives support in terms of policies and funds

for the key projects of packaging machinery, strive for the support of the state in terms of policies and funds, so as to mobilize the enthusiasm of backbone enterprises of packaging machinery to develop new products. Through the research and development process, we will support a number of backbone packaging machinery enterprises with innovative spirit, cultivate our own professional design team, and create brand-name packaging machinery products with Chinese characteristics

adjust the industrial structure, improve the concentration of production, promote professional and serial production, improve product quality and adaptability to the market where the export amount of extruder is lower than that of the same period last year; Accelerate the establishment of innovation system and form the self-development ability of enterprises as soon as possible. We will vigorously promote the use of cad/cam technology in the industry to refine, refine, specialize and strengthen China's packaging machinery products

strengthen management, break the boundaries of industries and departments, establish an overall concept, optimize the organizational structure, and realize industrial assets
