This aluminum laminated film is a multilayer packaging material for building pouch cell cases, used as the outer casing of polymer Li-ion batteries. Each roll is 113 μm thick, 400 mm wide and 10 m long.
The laminate runs from a shiny polyamide outer layer (0.025mm) through a polyester-polyurethane adhesive to a 0.040mm aluminum foil core to JIS A8079/A8021, then a urethane-free adhesive and a 0.040mm polypropylene inner layer with a mat finish. The structure supports a molding depth of ≥ 5.0 mm and offers good electrical insulation.
For cell sealing, the film is hot sealed at 180-190 °C and reaches a heat seal strength of more than 22.5N/15mm. Its moisture vapor / O2 transmission rate is specified as 200 ppm / 5 years, and laminate strength exceeds 2N/15mm at the nylon/Al interface and 5N/15mm at the Al/CPP interface.
- Forming the casing of polymer Li-ion pouch cell batteries.
- Deep-drawing pouch cups for laboratory cell assembly, with a molding depth of ≥ 5.0 mm.
- Heat sealing pouch cells at 180-190 °C to enclose the electrode stack.
