This aluminum-plastic film requires hot sealing at 180–190°C with controlled pressure (0.2 MPa) and dwell time (2 seconds) to achieve a minimum heat seal strength of 29.4 N/15 mm. The laminate structure must maintain interlayer bond strengths above 2 N/15 mm for Nylon/Al and above 5 N/15 mm for Al/CPP to prevent delamination during pouch cell assembly.
- Hot Sealing Requirement: The film must be sealed at 180–190°C at 0.2 MPa for 2 seconds to achieve the specified heat seal strength of over 29.4 N/15 mm.
- Laminate Strength Requirement: Interlayer adhesion must exceed 2 N/15 mm for the Nylon/Al interface and 5 N/15 mm for the Al/CPP interface to ensure structural integrity during forming and sealing.
- Solvent Retention Limit: Residual solvent content must be less than 5 mg/m² to avoid electrolyte contamination and battery performance degradation.
- Molding Depth Capability: The film must support a molding depth of at least 5.0 mm without cracking or delamination to accommodate pouch cell geometry.
- Moisture Barrier Requirement: Moisture vapor transmission rate must be below 200 ppm over 5 years to prevent battery degradation from internal moisture.
What pouch-forming depth can the 113 μm 110 mm×5 m aluminum-plastic film support?
The film is qualified for a minimum molding depth of 5.0 mm per the quality inspection specification. Its layer stack—0.025 mm polyamide, 0.040 mm aluminum foil (JIS A8079/A8021), adhesive layers, and 0.040 mm polypropylene—is designed for pouch-cell deep-draw forming. Actual forming depth should be confirmed with your specific tooling and process conditions.
What heat-sealing conditions are specified for this aluminum-plastic film?
The hot sealing condition is specified at 180–190 °C. The heat seal strength requirement is more than 29.4 N/15 mm when sealed at 200 °C, 0.2 MPa, for 2 seconds on heatsealing equipment, so the sealing system should be able to hold temperature, pressure, and dwell time within this operating range.
What barrier and surface-quality limits should be checked before using this film in a pouch cell?
The moisture vapor/O2 transmission rate is specified as 200 ppm / 5 years, and solvent retention is below 5 mg/m². Surface inspection limits include impurities up to 1 mm in diameter, clear fish eyes up to 2 mm in diameter, and colored fish eyes up to 1 mm in diameter, with pinhole acceptance subject to the applicable aluminum foil standard.
This 113 μm aluminum-plastic film roll (110 mm × 5 m) offers high laminate strength and excellent moisture barrier for pouch cell assembly, but requires precise hot sealing conditions and accepts minor defects that may affect critical applications.
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; heat seal strength exceeds 29.4 N/15 mm at 200°C, ensuring robust mechanical integrity during pouch formation and sealing.
- Excellent moisture barrier performance: Moisture vapor and oxygen transmission rate is specified as 200 ppm over 5 years, providing long-term hermetic protection for battery electrolytes.
Trade-offs
- Precise hot sealing conditions required: Hot sealing must be performed at 180–190°C with controlled pressure and dwell time (e.g., 200°C, 0.2 MPa, 2 sec) to achieve the specified heat seal strength, demanding calibrated equipment and process control.
- Acceptable defect limits may affect yield: The film permits pinholes per aluminum foil standard, impurities up to 1 mm diameter, and fish eyes up to 2 mm (clear) or 1 mm (colored), which could compromise barrier integrity in high-reliability applications.
