This aluminum-plastic film requires controlled hot sealing at 180-190°C to achieve adequate bond strength. The laminate must maintain minimum peel strengths of 2 N/15 mm for Nylon/Al and 5 N/15 mm for Al/CPP to prevent delamination.
- Hot Sealing Temperature: Hot sealing must be performed at 180-190°C.
- Laminate Strength: Laminate strength must exceed 2 N/15 mm for Nylon/Al and 5 N/15 mm for Al/CPP.
- Heat Seal Strength: Heat seal strength must exceed 29.4 N/15 mm when tested at 200°C, 0.2 MPa, and 2 seconds.
- Solvent Retention: Solvent retention must be less than 5 mg/m².
- Moisture and Oxygen Barrier: Moisture vapor and oxygen transmission rate is limited to 200 ppm over 5 years.
What is the laminate strength specification for this 113 μm aluminum-plastic film and how does it impact pouch cell durability?
The laminate strength is specified as Nylon/Al more than 2 N/15 mm and Al/CPP more than 5 N/15 mm. These values ensure robust adhesion between the polyamide outer layer and aluminum foil, and between aluminum and polypropylene inner layer, which is critical for preventing delamination during battery cycling and sealing processes.
What hot sealing conditions are required for this 113 μm aluminum-plastic film?
The film requires a hot sealing condition of 180-190°C. For heat seal strength qualification, the test condition is 200°C at 0.2 MPa for 2 seconds on heatsealing equipment, achieving a minimum strength of 29.4 N/15 mm wide. The lower range (180-190°C) is recommended for actual pouch sealing to balance seal integrity and material integrity.
What is the solvent retention specification and why is it important for battery pouch film?
The solvent retention is less than 5 mg/m². This low level is critical to avoid contamination of the battery electrolyte, which can degrade performance and safety. Combined with a moisture vapor transmission rate of 200 ppm over 5 years, the film provides a reliable barrier for long-term pouch cell operation.
This 113 μm aluminum-plastic film sheet provides high laminate and heat seal strength for reliable pouch cell sealing, along with a deep draw capability of ≥5.0 mm for complex pouch geometries. However, it requires precise hot sealing conditions (180–190°C, 0.2 MPa, 2 sec) and the sheet format necessitates additional cutting or punching before forming.
Positive
- High laminate and heat seal strength: Laminate strength exceeds 2 N/15 mm for Nylon/Al and 5 N/15 mm for Al/CPP, with heat seal strength >29.4 N/15 mm at 200°C, ensuring robust pouch sealing.
- Deep draw capability for complex geometries: Molding depth ≥5.0 mm allows forming of deep pouch cavities, enabling flexible cell design in prototype and small-scale production.
Trade-offs
- Requires precise hot sealing conditions: Optimal sealing demands a narrow temperature range of 180–190°C, 0.2 MPa pressure, and 2 sec dwell time, which may require dedicated heat sealing equipment and process control.
- Sheet format requires additional processing steps: The 400 mm × 500 mm sheet must be cut or punched to desired pouch dimensions before forming, adding handling complexity and potential for material waste.
