Description
Aluminum Laminated Film for Pouch Cell Case – Width: 400 mm, Length: 7.5 m
This aluminum laminated film (115 μm thickness) is specifically designed for use as a protective and structural casing material in polymer lithium-ion pouch cells. With its multi-layer construction—consisting of polyamide, aluminum foil, and polypropylene—this film offers excellent barrier properties against moisture, oxygen, and chemicals while maintaining flexibility, mechanical durability, and dimensional stability. It is an essential material for high-energy-density battery packaging in both R&D and industrial-scale cell production.
