As China's economy grows stronger and stronger, the packaging industry is also rapidly developing at an average annual rate of 18%. However, in the rapid development of China's packaging industry, a large number of complete sets of equipment with high technological content still rely on imports. In this regard, many industry experts have pointed out without hesitation that the excessive dependence of China's packaging machinery on foreign high-end technology has become a serious issue that has constrained the sustained and stable development of China's packaging industry.
It is understood that a two-way stretching device for plastic film, a production line of nearly 100 million yuan, has been introduced since the 1970s. So far, 110 lines of such production lines have been imported. In addition, aseptic packaging boxes and filling equipments that are used in large quantities in the dairy industry are almost all provided by the Swedish company Tetra Pak. Experts pointed out that although the introduction of a large number of advanced equipment has greatly accelerated the pace of development of China's packaging industry, narrowing the gap between China's packaging industry and developed countries. However, we cannot rely on foreign high-end technologies and technical equipment. This is because foreign technology 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 technological level of China's packaging industry; it is not conducive to the development of its own intellectual property rights, and is not conducive to Cultivate your own professional designer. And the packaging industry is also a supporting industry, involving many areas of the national economy, especially the food industry and beverage industry, but also depends on the packaging industry's technological progress, and supporting services. Therefore, we can no longer ignore the negative impact of the backwardness of packaging machinery on the overall development of China's packaging industry.
