This roll of aluminum-plastic film is designed for pouch cell battery assembly and requires controlled heat sealing conditions to ensure bond integrity. The laminate must be processed within specified temperature and pressure parameters to avoid delamination or seal failure.
- Heat Sealing: Heat seal the film at 180–190°C with a pressure of 0.2 MPa for 2 seconds to achieve a seal strength exceeding 29.4 N/15 mm.
- Laminate Strength: Maintain laminate strength above 2 N/15 mm for the nylon/aluminum interface and above 5 N/15 mm for the aluminum/CPP interface.
- Moisture Barrier: The film provides a moisture vapor transmission rate of 200 ppm over 5 years, requiring dry storage and handling to preserve barrier performance.
- Solvent Retention: Ensure solvent retention remains below 5 mg/m² to prevent contamination of the battery cell.
- Molding Depth: The film supports a molding depth of at least 5.0 mm for pouch forming without rupture.
What is the achievable forming depth for this 113 μm aluminum-plastic film, and how does the layer structure support it?
The specified molding depth is ≥5.0 mm. The 113 μm film comprises a 0.025 mm polyamide layer, 0.040 mm aluminum foil (JIS A8079/A8021), and 0.040 mm polypropylene, with adhesive layers, providing the required ductility and strength for deep drawing in pouch cell forming.
What are the critical hot sealing parameters required to achieve the specified heat seal strength?
The heat seal strength must exceed 29.4 N/15 mm width when sealed at 200°C, 0.2 MPa, for 2 seconds. The recommended hot sealing temperature range is 180–190°C. These parameters ensure reliable pouch sealing under production conditions.
How does the film's moisture barrier performance compare to standard pouch film specifications, and what is the solvent retention level?
The moisture vapor/O2 transmission rate is specified as 200 ppm over 5 years, indicating a low transmission rate suitable for long-term battery storage. Solvent retention is less than 5 mg/m², minimizing electrolyte contamination risks.
This 113 μm aluminum-plastic film roll offers strong laminate adhesion and low permeability, suitable for pouch cell forming and sealing. However, sealing requires precise temperature control and surface quality tolerances must be considered for high-reliability prototypes.
Positive
- High laminate and heat seal strength: Laminate strength for Nylon/Al >2 N/15 mm and Al/CPP >5 N/15 mm; heat seal strength >29.4 N/15 mm at 200°C, 0.2 MPa, 2 sec, ensuring robust pouch seals.
- Low moisture and oxygen transmission: Moisture vapor and O2 transmission rate of 200 ppm over 5 years, providing excellent barrier properties for long-term battery stability.
Trade-offs
- Precise hot sealing temperature required: Hot sealing condition specified at 180-190°C; deviations may compromise seal integrity, requiring controlled equipment.
- Surface quality limits for pinholes and impurities: Pinholes are subject to applicable aluminum foil standard (not zero), and impurities up to 1 mm diameter are allowed, which may affect consistency in critical applications.
