This punched aluminum-plastic film requires hot sealing at 180-190°C with 0.2 MPa pressure for 2 seconds to achieve a heat seal strength exceeding 29.4 N/15 mm. The laminate must exhibit Nylon/Al adhesion >2 N/15 mm and Al/CPP adhesion >5 N/15 mm, with solvent retention below 5 mg/m2 and moisture vapor transmission limited to 200 ppm over 5 years.
- Hot Sealing Condition: The film must be sealed at 180-190°C with 0.2 MPa pressure for 2 seconds to achieve a heat seal strength greater than 29.4 N/15 mm.
- Laminate Strength: Nylon/Al adhesion must exceed 2 N/15 mm and Al/CPP adhesion must exceed 5 N/15 mm to prevent delamination.
- Solvent Retention: Solvent retention must be less than 5 mg/m2 to avoid contamination in battery cells.
- Moisture Barrier: Moisture vapor transmission rate is limited to 200 ppm over 5 years to maintain cell integrity.
- Molding Depth: The film must support a molding depth of at least 5.0 mm without failure.
This procedure describes the hot sealing and quality inspection steps for the aluminum-plastic film used in pouch cell assembly. Proper sealing conditions and verification of laminate strength ensure reliable battery performance.
Required Equipment: Heat sealing equipment, Laminate strength tester, Solvent retention measurement device
- Inspect film surface
Inspect the film surface for pinholes, impurities, and fish eyes larger than allowed tolerances before use. - Set sealing parameters
Set the heat sealing equipment to a temperature range of 180-190°C and a pressure of 0.2 MPa. - Apply heat seal
Apply the heat seal for exactly 2 seconds to achieve proper bonding. - Verify heat seal strength
Verify the heat seal strength exceeds 29.4 N/15 mm using a tensile tester. - Confirm laminate strength
Confirm that the laminate strength meets Nylon/Al >2 N/15 mm and Al/CPP >5 N/15 mm. - Measure solvent retention
Measure solvent retention to ensure it is below 5 mg/m2. - Check moisture barrier
Check moisture vapor transmission rate to confirm it remains within 200 ppm over 5 years.
What is the laminate strength and heat seal strength of the L62×W46×T4 mm punched aluminum-plastic film?
The laminate strength is Nylon/Al more than 2 N/15 mm and Al/CPP more than 5 N/15 mm. The heat seal strength is more than 29.4 N/15 mm wide at 200°C x 0.2 MPa x 2 sec on heatsealing equipment.
What are the hot sealing conditions and molding depth for this pouch cell aluminum-plastic film?
The hot sealing condition is 180–190°C. The molding depth is ≥ 5.0 mm, indicating the film can be formed to this depth without compromising integrity.
What is the moisture vapor and oxygen transmission rate for the L62×W46×T4 mm punched aluminum-plastic film?
The moisture vapor and oxygen transmission rate is specified as 200 ppm over 5 years, corresponding to a very low transmission rate suitable for long-term pouch cell storage.
This punched aluminum-plastic film (L62×W46×T4 mm) offers high laminate and heat seal strength suitable for pouch cell prototyping, with a moisture barrier rated at 200 ppm over 5 years. However, its fixed dimensions and required sealing temperature of 180-190°C demand precise equipment and handling.
Positive
- High laminate and 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 integrity during assembly and cycling.
- Excellent moisture barrier: Moisture vapor and oxygen transmission rate is specified as 200 ppm over 5 years, providing long-term protection for moisture-sensitive battery electrolytes.
Trade-offs
- Fixed punched dimensions: The film is pre-punched to L62×W46×T4 mm, limiting flexibility for custom pouch depths or sizes without additional forming equipment.
- Narrow hot sealing window: Hot sealing requires 180-190°C, demanding precise temperature control on heat sealing equipment to avoid under- or over-sealing.
