Cathode: aluminum foilAnode: copper foilCLOSEUPCopper foilAluminum foilPackaging materials for medical instrumentsCleanroomComprehensive capabilities for developing and manufacturing various kinds of foil made from aluminum, copper, tin and leadAdvantage1Easy to process and attractive in appearance, metallic foils are used in all kinds of everyday products. UACJ’s foil business supplies products to a wide range of industries by manufacturing a diverse lineup of metallic foils made not only from aluminum but also copper, tin and lead. Production conditions complying with good manufacturing practices to ensure safe and dependable productsSince packaging materials for food and medical products require a very high level of hygienic management, our main foil factories maintain extremely hygienic production environments to prevent any foreign substances from affecting the products. All of these foil factories are equipped with air showers, cleanrooms, and separate booths for each production process. This strict production system complies with good manufacturing practices set for medical product manufacturing and quality control. Advantage2Japan’s sole manufacturer of foil for each electrode of lithium-ion batteriesLithium-ion batteries are used in a broad array of products, from smartphones and notebook computers to electric vehicles. The electrodes of these batteries are made from foil, specifically aluminum foil for the cathode and copper foil for the anode. UACJ is the only manufacturer in Japan that makes materials for both of these electrodes, and has secured a leading share of the market for cathode aluminum foil in particular. By drawing on its advanced alloying and flat-rolling technologies, UACJ’s foil business contributes to the production of lithium-ion batteries with higher output, lighter weight, and longer service life.16
