This aluminum-plastic film requires heat sealing at 180-190°C and must achieve interlayer laminate strength above specified thresholds. The film's moisture barrier and solvent retention properties demand controlled processing conditions to maintain pouch integrity.
- Heat Sealing Requirement: Heat sealing must be performed at 180-190°C using appropriate heatsealing equipment to achieve the specified seal strength.
- Laminate Strength Specification: The interlayer laminate strength must exceed 2 N/15 mm for Nylon/Al and 5 N/15 mm for Al/CPP to prevent delamination.
- Moisture Barrier Constraint: The film provides a moisture vapor transmission rate of 200 ppm over 5 years, requiring hermetic sealing to maintain battery performance.
- Solvent Retention Limit: Solvent retention must remain below 5 mg/m² to avoid contamination of the electrolyte within the pouch cell.
- Molding Depth Capability: The film supports a molding depth of at least 5.0 mm under proper forming conditions for pouch cell geometry.
What is the layer structure and material specification of this 91 μm aluminum-plastic film?
The specified construction is a laminated aluminum-plastic structure with 0.025 mm polyamide (JIS Z1714), 4–5 g/m² polyester-polyurethane adhesive, 0.040 mm aluminum foil (JIS A8079/A8021), 2–3 g/m² urethane-free adhesive, and 0.040 mm polypropylene. The product is 91 μm thick and supplied as a 120 mm × 300 m roll, providing 36 m² per roll.
What pouch-forming capability and barrier performance does this 91 μm roll film provide?
The film is supplied for battery pouch forming, sealing, and prototype assembly, with a specified molding depth of ≥5.0 mm. The source also lists a moisture vapor/O2 transmission specification of 200 ppm/5 years, good electrical insulation, and a CPP/CPP slip factor of <1.0.
What heat-sealing equipment conditions are required to achieve the specified seal strength?
The film's hot sealing condition is stated as 180–190 °C. Heat seal strength is specified as >29.4 N/15 mm width when sealed at 200 °C, 0.2 MPa, for 2 s on heat-sealing equipment.
This 91 μm aluminum-plastic film roll offers robust laminate construction with high heat seal strength (>29.4 N/15mm) and low moisture/oxygen transmission (200 ppm/5 years), suitable for pouch cell assembly. Sealing requires precise temperature control at 180–190°C.
Positive
- High laminate and heat seal strength: Nylon/Al laminate strength >2 N/15mm, Al/CPP >5 N/15mm, and heat seal strength >29.4 N/15mm at 200°C, 0.2 MPa, 2 sec ensure durable pouch seals under typical sealing conditions.
- Low moisture and oxygen transmission: Moisture vapor and oxygen transmission rate of 200 ppm over 5 years provides long-term electrolyte containment, critical for battery shelf life and performance stability.
Trade-offs
- Hot sealing requires precise temperature control: The specified hot sealing condition of 180–190°C demands accurate temperature regulation and compatible heat-sealing equipment; deviations may compromise seal integrity.
