Application advantages of coated iron in printing iron can industry

Compared with traditional printed iron can materials: 1) Laminated iron has corrosion resistance and rust resistance that coating plates can’t match (traditional coating plates have the contradiction between corrosion resistance and adhesion), which is good for ketchup packaging cans, etc. For two-piece food packaging cans, it is a very ideal packaging material; 2) The coated iron has good stability, weather resistance and aging resistance, and can adapt to harsh environments without falling off and rust; 3) Processing performance Excellent, resistant to deep drawing, abrasion, and not easy to be damaged during processing. Due to its smooth surface and the lubricating effect of the plastic film, it is easier to form in the processing of metal cans; 4) The appearance is smooth, smooth, decorative, and feels good. . Compared with the traditional printing iron can making process: 1) Film-coated iron is a composite material with the dual characteristics of plastic film and metal plate. Generally, cold-rolled sheet can be used for coating, and it is not necessary to use tinplate as the substrate to produce the coating. Iron, the cost advantage is obvious; 2) The production of coated iron is a continuous high-speed production line for coils, which is faster than the traditional printing process; 3) Because the printed plastic film and the laminated film can be completed at one time, compared with the traditional printing iron The process has the characteristics of low energy consumption, high speed, and less materials; 4) The production of coated iron requires less equipment, high degree of automation, smaller investment, and less floor space. In addition, it has outstanding performance in energy saving and environmental protection. The use and popularization of coated iron is known as the 'green revolution' of metal food packaging. Coated iron also has some shortcomings. For example, the polymer resin film and the metal matrix are prone to interface separation and film damage during the deep drawing process, which will lose the protection of the metal matrix and cause the metal matrix to corrode quickly, which will make the coated iron The excellent properties of packaging materials are lost [2]. By studying the defect formation mechanism and mechanism in the deep drawing process of coated iron cans, and optimizing related process parameters to reduce the effect of defects on product performance, it is very necessary for the application of coated iron products.
