This aluminum-plastic laminate film requires controlled hot sealing conditions to achieve specified bond strengths. The film provides a moisture barrier with a transmission rate equivalent to 200 ppm over 5 years.
- Hot Sealing Temperature Range: Hot sealing must be performed at 180-190°C to ensure proper bond integrity.
- Laminate Strength Requirements: Minimum laminate strength is 2 N/15 mm between nylon and aluminum and 5 N/15 mm between aluminum and CPP.
- Heat Seal Strength Requirement: Heat seal strength must exceed 29.4 N/15 mm when sealed at 200°C, 0.2 MPa, for 2 seconds.
- Moisture and Oxygen Barrier: The film maintains a moisture vapor transmission rate equivalent to 200 ppm over 5 years.
- Solvent Retention Limit: Solvent retention must be less than 5 mg/m² to avoid contamination.
What is the significance of the laminate strength values (Nylon/Al >2 N/15mm, Al/CPP >5 N/15mm) for pouch cell reliability?
The laminate strength values indicate the adhesion between layers. Nylon/Al >2 N/15mm ensures the outer insulating layer remains bonded, while Al/CPP >5 N/15mm ensures the aluminum core adheres to the polypropylene sealing layer, critical for preventing delamination during forming and cycling. The source states these values as laminate strength specifications.
What hot sealing conditions are recommended for this aluminum-plastic film to achieve optimal heat seal strength?
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. These parameters are specified in the quality inspection section to ensure reliable sealing.
What are the acceptable impurity and fish eye limits for this aluminum-plastic film, and do they affect pouch cell barrier performance?
The film allows impurities up to 1 mm diameter and fish eyes up to 2 mm (clear) or 1 mm (colored). These limits are specified in the quality inspection section. They are typical for battery-grade aluminum laminated film to avoid pinholes or weak points that could compromise the barrier integrity. The film also has a moisture vapor/O2 transmission rate of 200 ppm over 5 years, indicating good barrier properties.
This 113 μm aluminum-plastic film sheet (200×120 mm, 50-pack) is designed for pouch cell prototyping, offering a laminate strength of >2 N/15 mm (Nylon/Al) and >5 N/15 mm (Al/CPP) with a heat seal strength >29.4 N/15 mm at 200°C, 0.2 MPa, 2 sec, and a molding depth ≥5.0 mm for deep-drawn forming.
Positive
- High laminate and heat seal strength: The film exhibits Nylon/Al laminate strength >2 N/15 mm, Al/CPP >5 N/15 mm, and heat seal strength >29.4 N/15 mm at 200°C, 0.2 MPa, 2 sec, ensuring robust pouch integrity under thermal and mechanical stress.
- Good barrier and formability properties: Moisture vapor/O2 transmission rate is specified at 200 ppm over 5 years, and molding depth ≥5.0 mm indicates suitability for deep-drawn pouch cell geometries without compromising barrier performance.
Trade-offs
- Precise hot sealing temperature required: The film requires a hot sealing condition of 180–190°C, necessitating accurate temperature control on heat-sealing equipment to achieve reliable seals without damaging the laminate.
- Residual solvent and defect tolerances: Solvent retention is <5 mg/m², and specifications allow impurities ≤1 mm diameter and fish eyes ≤2 mm, meaning users must inspect for potential pinholes or inclusions that could affect long-term reliability in sensitive cell environments.
