With the increasing application and demand of aluminum foil, the domestic aluminum foil industry continues to develop, especially the aluminum foil industry for flexible packaging has developed rapidly. In addition to the use of high-quality double zero aluminum foil in electrolytic capacitors, more than 90% of aluminum foil for packaging is double zero aluminum foil. At present, China is the world's largest producer of aluminum foil, but there is still a gap between the production of double-zero aluminum foil and the overall quality of its products. At present, the quality status and existing problems of domestic double zero aluminum foil, some suggestions for improving the quality level of double zero aluminum foil are proposed. The quality level of domestic double zero aluminum foil is more than that of aluminum foil production process, and the processing technology is difficult. Double zero aluminum foil rolling is the ultimate thickness of aluminum foil rolling. The only countries in the world that can produce aluminum foil with thickness as low as 0.0059 mm are only China, the United States and so on. From a technical point of view, it is not difficult to produce double-zero aluminum foil, but it is not easy to produce high-quality double-zero aluminum foil on a large scale. The production technology and quality level of domestic double zero aluminum foil are compared with the international advanced level. At present, most of the domestic manufacturers producing double-zero aluminum foil products can achieve a minimum thickness of 0.006 mm, a thickness tolerance of ± (3% to 5%), and a double-zero foil product produced by HTMM with a thickness of 0.0059 mm. The tolerance is about ± 5%.
