Flexographic printing is currently the main printing and processing method in the field of packaging and printing, and its proportion in this field is increasing year by year. According to data statistics, the market share of various printing processes in the packaging printing industry in the United States in 2000 was roughly as follows: offset printing was 40%, flexo printing was 32%, gravure printing was 18%, and others accounted for 10%; The market share of the printing process has changed a lot: Offset 36%, flexo 39%, gravure 15%, and other 10%. It is expected that the proportion will increase to about 50% next year. Overview of China's flexo is in its infancy, the market share is still very low (about 3% to 5%), but, with the rapid development of China's flexographic printing in the packaging printing process, must also be like Europe and the United States In the packaging printing has become an important printing method, flexographic printing folding cartons in China will have a broader space for development.

The general folding carton production process is generally followed by printing, followed by post-press processing, such as bronzing, glazing, and finally die-cutting. After each production process, a large number of semi-finished products will appear. Before these semi-finished products enter the next production process, people need to spend a lot of time and energy to transport and handle these semi-finished products, and need to provide ample space for storing these semi-finished products. This means that there will be a lot of time and effort and a lot of space is occupied. At the same time, the previous process often becomes the source of failure or error in the next process. Whether it is in the printing process or in the process of post-press processing errors or errors will lead to scrapped finished products. The on-line system of the flexographic printing press has integrated the production process of the folding cartons. Since it involves printing, glazing, die-cutting, indentation, and baling and forming, the production process is shortened, and the probability of error occurrence is reduced. The production cost.

In Europe, there are such folding cartons manufacturing companies. They mainly administer printing kits and instructions to the factory. When the kits are provided by the pharmaceutical factory, the instructions for medicines have been placed in the kits. They usually form an online system of flexographic printing presses and packaging filling machines. This online system can directly print a large number of folding cartons and product manuals, and then perform filling. Using such a system not only saves production raw materials, but also saves 80% of the entire production process, eliminating the need for operators and quality control personnel. At the same time, people do not have to worry about whether or not the contents of the package match, because in the past when people packaged medicine, people generally equipped with a machine identification system on the folder gluer, so that it automatically recognizes the identification barcode on the paste cartridge of the box. This ensures that the package matches the contents. Now that the online system has been adopted, the occurrence of this mismatch has not been eliminated.
