Aluminum laminated film for pouch cell case is an important packaging material, mainly composed of aluminum foil, nylon layer, heat sealing layer, etc. Among them, aluminum foil is one of the key materials, which has the advantages of high barrier properties, good processing performance and corrosion resistance. In the manufacturing process of soft-pack batteries, laminated aluminum foil plays a role in protecting the internal structure of the battery and improving the sealing performance of the battery. The manufacturing process of laminated aluminum foil is relatively complex and requires multiple processes, such as gluing, lamination, hot pressing, etc. During the manufacturing process, factors such as the thickness, surface quality, and amount of glue applied on each layer need to be controlled to ensure the performance and reliability of the final product. At the same time, laminated aluminum foil also needs to undergo strict testing and certification to ensure that it meets relevant standards and regulations.
