This aluminum-plastic film for pouch cells requires controlled hot sealing conditions and meets specific laminate strength thresholds. The material exhibits limited moisture vapor transmission and solvent retention constraints to ensure battery integrity.
- Hot Sealing Temperature: The film must be sealed at a temperature between 180°C and 190°C.
- Heat Seal Parameters: Achieve a heat seal strength exceeding 29.4 N per 15 mm width at 200°C, 0.2 MPa, and 2 seconds.
- Laminate Adhesion: Interlayer adhesive strength must exceed 2 N/15 mm for Nylon/Al and 5 N/15 mm for Al/CPP.
- Moisture Barrier: Moisture vapor transmission is limited to 200 ppm over a 5-year period.
- Solvent Retention: Residual solvent content must be maintained below 5 mg per square meter.
How does the 0.040 mm aluminum foil thickness in this 152 μm aluminum-plastic film compare to the polyamide and polypropylene layers in terms of barrier contribution?
The aluminum foil layer (0.040 mm ±0.004 mm, JIS A8079/A8021) serves as the primary moisture and oxygen barrier, with the laminate achieving a moisture vapor/O2 transmission rate of 200 ppm over 5 years. The polyamide (0.025 mm) provides mechanical strength, and polypropylene (0.040 mm) enables heat sealing. The laminate strength between nylon/Al is >2 N/15 mm and between Al/CPP is >5 N/15 mm.
What are the required heat sealing parameters for this aluminum-plastic film to ensure a pouch cell seal strength above 29.4 N/15 mm?
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. The polypropylene layer (0.040 mm) is the heat-sealable component.
What quality inspection parameters are specified for pinholes, impurities, and surface defects in this aluminum-plastic film?
The film has a matte finish surface quality. Pinholes are subject to the applicable aluminum foil standard. Impurities are limited to 1 mm or less in diameter, and fish eyes are limited to 2 mm or less (clear) or 1 mm or less (colored). The molding depth is ≥5.0 mm, and electrical insulation is good.
This 152 μm aluminum-plastic film roll offers a laminate strength of >5 N/15 mm (Al/CPP) and a molding depth of ≥5.0 mm, making it suitable for deep-drawn pouch cell forming. However, its hot sealing requires precise control at 180-190°C and 0.2 MPa, demanding compatible heat-sealing equipment.
Positive
- High Laminate and Heat Seal Strength: Laminate strength exceeds 5 N/15 mm between Al and CPP layers, and heat seal strength is >29.4 N/15 mm at 200°C, ensuring robust pouch seals.
- Deep Molding Capability: Molding depth of at least 5.0 mm allows reliable forming of deep pouch cavities for battery cell assembly.
Trade-offs
- Precise Hot Sealing Conditions: Requires 180-190°C and 0.2 MPa pressure on heat-sealing equipment to achieve proper seal, limiting compatibility with general-purpose sealers.
