This aluminum-plastic laminated film requires hot sealing at 180-190°C with a dwell time of 2 seconds at 0.2 MPa to achieve a heat seal strength exceeding 29.4 N/15 mm. The film exhibits a moisture vapor transmission rate of 200 ppm over 5 years and must be handled to avoid pinholes, impurities larger than 1 mm, and colored fish eyes exceeding 1 mm.
- Hot Sealing Conditions: Seal the film at 180-190°C using 0.2 MPa pressure for 2 seconds to achieve the specified heat seal strength.
- Laminate Strength Requirements: Ensure the nylon-to-aluminum laminate strength exceeds 2 N/15 mm and the aluminum-to-CPP laminate strength exceeds 5 N/15 mm.
- Environmental Sensitivity: The film allows a maximum moisture vapor transmission of 200 ppm over 5 years, requiring dry storage and controlled humidity during assembly.
- Solvent Retention Limit: Maintain solvent retention below 5 mg/m² to prevent contamination of the battery cell.
- Formability and Surface Quality: The film must achieve a molding depth of at least 5.0 mm while maintaining a matte surface free of pinholes and impurities above 1 mm diameter.
How do the laminate strength values (Nylon/Al >2 N/15 mm and Al/CPP >5 N/15 mm) compare to the heat seal strength requirement of >29.4 N/15 mm for this 113 μm aluminum-plastic film?
The laminate strength between aluminum and CPP is greater than 5 N/15 mm, while the heat seal strength at 200°C, 0.2 MPa, and 2 seconds is greater than 29.4 N/15 mm. This indicates that the heat seal interface is significantly stronger than the internal laminate layers, consistent with the film's design for pouch cell sealing where the seal must withstand internal pressures.
What hot sealing conditions are required to achieve the specified heat seal strength for this 113 μm aluminum-plastic film?
The hot sealing condition is specified at 180–190°C for general use. For a reference heat seal strength exceeding 29.4 N/15 mm, the film requires sealing at 200°C, 0.2 MPa, and 2 seconds on heat-sealing equipment. These parameters are critical for achieving reliable pouch cell sealing without delamination.
What are the moisture vapor transmission rate and solvent retention specifications for this 113 μm aluminum-plastic film, and why are they important for battery pouch integrity?
The moisture vapor and oxygen transmission rate is 200 ppm over 5 years, and solvent retention is less than 5 mg/m². These low transmission and retention values are essential for maintaining a dry internal environment in pouch cells, preventing electrolyte degradation and ensuring long-term electrochemical stability.
This 113 μm aluminum-plastic film provides high heat seal strength (>29.4 N/15 mm) and low moisture vapor transmission (200 ppm over 5 years) for reliable pouch cell sealing, but the tight hot sealing window (180-190°C) and thickness tolerances on polyamide and aluminum layers (±0.0025 mm and ±0.004 mm) require precise process control.
Positive
- High heat seal strength: Heat seal strength exceeds 29.4 N/15 mm at 200°C, 0.2 MPa, and 2 seconds, ensuring robust hermetic sealing for pouch cells.
- Low moisture and oxygen transmission: Moisture vapor and oxygen transmission rate is specified as 200 ppm over 5 years, contributing to long-term battery stability and reduced degradation.
Trade-offs
- Precise hot sealing temperature required: The hot sealing condition is specified at 180-190°C, demanding tight temperature control on heatsealing equipment to avoid seal failure or film damage.
- Thickness tolerances introduce variability: Polyamide layer thickness tolerance is ±0.0025 mm (10%) and aluminum foil tolerance is ±0.004 mm (10%), which can cause non-uniformity in laminate properties across the roll.
