This aluminum-plastic film requires hot sealing at 180-190°C and achieves a heat seal strength exceeding 29.4 N/15 mm when sealed at 200°C, 0.2 MPa for 2 seconds. The laminate must maintain nylon/aluminum adhesion above 2 N/15 mm and aluminum/CPP adhesion above 5 N/15 mm, with solvent retention below 5 mg/m² and molding depth at least 5.0 mm.
- Hot Sealing Condition: Hot sealing must be performed at 180-190°C to achieve proper bonding.
- Heat Seal Strength: Heat seal strength must exceed 29.4 N/15 mm when sealed at 200°C, 0.2 MPa for 2 seconds.
- Laminate Strength: Nylon/aluminum laminate strength must exceed 2 N/15 mm and aluminum/CPP laminate strength must exceed 5 N/15 mm.
- Solvent Retention: Solvent retention must be less than 5 mg/m² to avoid contamination.
- Molding Depth: Molding depth must be at least 5.0 mm for proper pouch formation.
What is the maximum molding depth achievable with this 91 μm aluminum-plastic film for pouch cell forming?
The molding depth is ≥5.0 mm, as specified in the quality inspection table. This indicates the film can be deep-drawn to at least 5 mm without rupture, which is critical for forming pouch cavities with sufficient capacity for electrode stacks.
What hot sealing conditions are required to achieve the specified heat seal strength for this pouch cell film?
The hot sealing condition is 180–190°C, and the heat seal strength test is performed at 200°C, 0.2 MPa, for 2 seconds. Under these conditions, the heat seal strength exceeds 29.4 N per 15 mm width, ensuring reliable sealing for battery assembly.
What are the acceptable impurity and fish-eye limits in this aluminum-plastic film?
Impurities are limited to ≤1 mm diameter, and fish eyes must be ≤2 mm diameter (clear) or ≤1 mm diameter (coloured). Pinholes are subject to the applicable aluminum foil standard. These quality controls help prevent defects that could compromise pouch integrity or cause short circuits.
This 91 μm aluminum-plastic film roll (120 mm width, 30 m length) is engineered for pouch cell battery forming and sealing, featuring a 5-layer laminate with heat seal strength >29.4 N/15 mm and deep draw capability ≥5.0 mm, suitable for prototyping and small-scale production.
Positive
- High heat seal and laminate strength: Heat seal strength exceeds 29.4 N/15 mm at 200°C, 0.2 MPa, 2 sec, and laminate strength between Al/CPP is >5 N/15 mm, ensuring robust seam integrity.
- Deep draw molding capability: Molding depth of ≥5.0 mm allows reliable forming of pouch cell cavities for prototype assembly.
Trade-offs
- Narrow width and fixed roll length: At 120 mm width and 30 m length, this roll is optimized for small-format pouch cells and may not accommodate larger cell designs without splicing.
- Specific heat sealing conditions required: Hot sealing requires 180–190°C, demanding precise temperature control and compatible heat sealing equipment to achieve specified bond strength.
