This film requires hot sealing within a temperature range of 180–190°C to achieve proper adhesion between layers. Quality constraints include minimum laminate strength values and a solvent retention limit below 5 mg/m².
- Hot Sealing Temperature Range: The hot sealing condition must be maintained between 180°C and 190°C to ensure adequate bond formation.
- Heat Seal Strength Requirement: Heat seal strength must exceed 29.4 N per 15 mm width when sealed at 200°C with 0.2 MPa pressure for 2 seconds.
- Laminate Strength Specifications: Laminate strength must be greater than 2 N/15 mm for the nylon/aluminum interface and greater than 5 N/15 mm for the aluminum/CPP interface.
- Solvent Retention Limit: Solvent retention must be less than 5 mg per square meter to avoid contamination in battery applications.
- Molding Depth Minimum: The film must support a molding depth of at least 5.0 mm without delamination or pinhole formation.
What is the maximum molding depth achievable with this 113 μm aluminum-plastic film, and how does the laminate strength affect formability?
The molding depth is >=5.0 mm as specified in the quality inspection. The laminate strength between nylon and aluminum is >2 N/15 mm, and between aluminum and CPP is >5 N/15 mm, ensuring sufficient adhesion to withstand the forming process without delamination at this depth.
What are the required heat sealing parameters for this aluminum-plastic film to achieve a reliable seal in pouch cell assembly?
The recommended hot sealing condition is 180-190°C. At 200°C, 0.2 MPa, and 2 seconds on heat sealing equipment, the heat seal strength exceeds 29.4 N/15 mm width. This ensures a robust seal for lithium-ion pouch cells under standard production conditions.
What is the solvent retention limit and moisture vapor transmission rate of this film, and why are these critical for battery performance?
The solvent retention is less than 5 mg/m², and the moisture vapor/O2 transmission rate is 200 ppm over 5 years. Low solvent retention minimizes electrolyte contamination, while the low transmission rate prevents moisture ingress that could degrade battery performance and safety over the cell's lifetime.
This 113 μm aluminum-plastic laminate film, supplied as 400×300 mm sheets in packs of 50, is designed for pouch cell fabrication. It features a multilayer construction with controlled thicknesses and adhesives, offering a molding depth of ≥5.0 mm and a heat seal strength of >29.4 N/15 mm under specified conditions, making it suitable for prototyping and small-scale production. Its low moisture and oxygen transmission rate (200 ppm/5 years) supports long-term cell stability, but precise sealing parameters and contamination control are required.
Positive
- High Heat Seal Strength and Laminate Adhesion: Heat seal strength exceeds 29.4 N/15 mm at 200°C, 0.2 MPa, 2 sec, and laminate strength is >2 N/15 mm (Nylon/Al) and >5 N/15 mm (Al/CPP), ensuring robust pouch sealing and layer integrity.
- Low Moisture and Oxygen Transmission: Moisture vapor and oxygen transmission rate is 200 ppm per 5 years, minimizing electrolyte degradation and supporting long-term cell stability.
Trade-offs
- Precise Hot Sealing Conditions Required: Optimal sealing requires a narrow temperature window of 180-190°C and specific pressure/time parameters (200°C, 0.2 MPa, 2 sec), necessitating capable heat sealing equipment.
- Handling Sensitivity to Contamination: Solvent retention must be kept below 5 mg/m², and impurities are limited to ≤1 mm diameter, requiring cleanroom-level handling and storage to avoid defects.
