This aluminum-plastic laminate film requires controlled hot sealing between 180-190°C to achieve reliable pouch seals. The film exhibits a moisture vapor transmission rate of 200 ppm over 5 years, necessitating dry storage conditions.
- Hot Sealing Temperature Range: The film must be sealed at 180-190°C to ensure proper adhesion without thermal degradation of the polypropylene layer.
- Laminate Strength Requirements: Minimum peel strength of 2 N/15 mm between nylon and aluminum and 5 N/15 mm between aluminum and cast polypropylene is required to prevent delamination.
- Solvent Retention Limit: Residual solvent content must remain below 5 mg/m² to avoid contamination of the electrolyte or cell environment.
- Molding Depth Capability: The film supports a molding depth of at least 5.0 mm, setting a limit for the depth of the pouch cavity.
- Moisture Barrier Performance: The moisture vapor transmission rate of 200 ppm over 5 years imposes a constraint on the permissible humidity exposure during cell assembly.
What is the heat seal strength and recommended sealing conditions for this 113 μm aluminum-plastic film?
The heat seal strength exceeds 29.4 N/15 mm when sealed at 200°C, 0.2 MPa, for 2 seconds on heat-sealing equipment. The manufacturer specifies a hot sealing condition range of 180–190°C, with laminate strength requirements of nylon/Al >2 N/15 mm and Al/CPP >5 N/15 mm, as provided in the product's quality inspection table.
What are the layer thicknesses and adhesive types used in this pouch cell aluminum-plastic film?
The 113 μm film comprises a 0.025 mm polyamide layer (JIS Z1714, ±0.0025 mm), a 0.040 mm aluminum foil layer (JIS A8079 or A8021, ±0.004 mm), and a 0.040 mm polypropylene layer (±0.004 mm). Adhesives include a polyester-polyurethane adhesive at 4–5 g/m² between polyamide and aluminum, and a urethane-free adhesive at 2–3 g/m² between aluminum and polypropylene.
What quality control parameters ensure the reliability of this aluminum-plastic film for pouch cell assembly?
Key quality parameters include a molding depth of ≥5.0 mm, good electrical insulating properties, a moisture vapor and oxygen transmission rate of 200 ppm over 5 years, and solvent retention less than 5 mg/m². Surface quality is matte finish with pinholes per applicable aluminum foil standard, impurity diameter ≤1 mm, and fish-eye defects ≤2 mm (clear) or ≤1 mm (coloured).
This 113 μm aluminum-plastic film sheet offers a engineered laminate structure with polyamide, aluminum, and polypropylene layers, achieving >5.0 mm molding depth, >29.4 N/15 mm heat seal strength, and <5 mg/m2 solvent retention, suitable for pouch cell prototyping and assembly under controlled hot sealing conditions.
Positive
- Precise multi-layer laminate construction: The film comprises 0.025 mm polyamide, 0.040 mm aluminum foil, and 0.040 mm polypropylene layers with specified adhesive coatings, providing consistent laminate strength (Nylon/Al >2 N/15 mm, Al/CPP >5 N/15 mm) and a molding depth of at least 5.0 mm for reliable pouch forming.
- High heat seal strength and low solvent retention: Heat seal strength exceeds 29.4 N/15 mm at 200°C, 0.2 MPa, 2 sec, and solvent retention is less than 5 mg/m2, ensuring robust sealing integrity and minimal contamination risk in battery assembly.
Trade-offs
- Requires controlled hot sealing conditions: Optimal hot sealing is specified at 180-190°C; deviations may compromise seal quality, necessitating precise temperature control and compatible heatsealing equipment.
- Subject to aluminum foil pinhole standards: Pinhole defects are subject to applicable aluminum foil standards, and impurity limits (≤1 mm diameter) and fish eye limits (≤2 mm clear, ≤1 mm colored) are specified, requiring incoming inspection for critical applications.
