Product Description8021 8079 Aluminum foil for battery surface packaging aluminum-plastic composite film 0.016 0.05mm
Aluminum foil for lithium battery soft pack aluminum-plastic film
In the three-layer structure of aluminum-plastic composite film, aluminum foil, as the middle layer, mainly plays the role of preventing the infiltration of water vapor outside the battery and preventing the leakage of internal electrolyte. In order to ensure the long-term stable and safe operation of the battery, the aluminum foil for aluminum-plastic film needs to have extremely high barrier properties, good cold stamping formability, puncture resistance and stability.
8021 aluminum foil performance advantages
1.It has excellent moisture resistance, light shielding and extremely high barrier ability.
2.It is non-toxic and odorless, safe and hygienic.
3.Aluminum foil after compounding, printing and gluing is widely used as packaging material.
Henan Yongsheng 8021 aluminum foil
1.Surface Quality: The aluminum foil features an oil-free, smooth surface, ensuring excellent bonding during the aluminum-plastic film lamination process. This significantly reduces the risk of delamination or detachment.
2.Enhanced Durability: The product offers superior resistance to stamping deformation and puncture.
3.Performance Specifications: Yongsheng Aluminum's 8079 battery soft-pack foil achieves a tensile strength of 90-110Mpa, elongation of 13%-18%, and a cupping value of 6.2-7.3mm. Its surface is free from defects such as oil contamination, pinholes, bumps, scratches, oxidation marks, wrinkles, or embedded foreign matter.
4.Advanced Manufacturing: The production line incorporates an online pinhole detection system and ultrasonic welding technology. Capable of processing high-end foils for batteries, electronics, and pharmaceuticals, the facility utilizes five-tier reel racks to enhance surface cleanliness significantly.
Henan Yongsheng Aluminum ranks among the limited number of domestic manufacturers capable of meeting the stringent processing requirements for lithium battery aluminum-plastic film.
