This multi-layer barrier composite requires processing in a controlled environment to prevent contamination of the sealing interface. The aluminum foil core must be formed with a draw depth of at least 5.0 mm to avoid mechanical necking and interlayer delamination.
- Deep Drawing Depth Constraint: The material supports a cold-forming draw depth of ≥5.0 mm without localized mechanical necking or interlayer delamination faults.
- Electrolyte Compatibility: The inner cast polypropylene sealing layer is formulated to resist aggressive organic solvents commonly used in lithium-ion electrolytes.
- Cleanroom Handling Requirement: The film must be handled in a cleanroom or dry-room environment to avoid particulate contamination on the sealing surfaces.
This procedure covers the cutting, forming, and inspection of the laminated film to produce pouch cell packaging. Proper execution maintains the barrier integrity and prevents delamination during deep drawing.
Required Equipment: Cleanroom or dry-room workspace, Precision cutter or automatic punch machine, Cold-forming deep drawing press, Visual inspection station with magnifier
- Prepare the workspace and film
Unroll the aluminum laminated film onto a clean, dry surface within a controlled environment to minimize contamination. - Cut the film to pouch dimensions
Cut the film to the required pouch footprint using a precision cutter or an automatic punch machine set to the specified dimensions. - Form the pouch via deep drawing
Position the cut film in the cold-forming deep drawing press and apply controlled pressure to achieve a draw depth of at least 5.0 mm. - Inspect the formed pouch
Visually examine the formed pouch under magnification for any signs of necking, delamination, or pinholes before proceeding to electrolyte filling.
How does the 113 μm total film thickness and specific layer composition influence the achievable forming depth of ≥5.0 mm for pouch cell packaging?
The 113 μm film consists of a 0.025 mm nylon outer layer, a 0.040 mm aluminum foil middle layer, and a 0.040 mm CPP inner layer, which collectively provide sufficient ductility to achieve a forming depth of ≥5.0 mm without compromising barrier integrity. The aluminum layer thickness is optimized to allow deep drawing without cracking, while the nylon layer ensures puncture resistance and mechanical strength during the forming process.
What heat-sealing equipment and conditions are required to achieve the stated ≥29.4 N/15mm seal strength with this aluminum laminated film?
The film is compatible with conventional heat-sealing equipment operating at 180–190°C; under standard test conditions at 200°C, the seal strength reaches ≥29.4 N/15mm. Proper alignment and dwell time are critical to ensure complete fusion of the 0.040 mm CPP inner layer for reliable sealing integrity.
What storage conditions are recommended to maintain the film's barrier performance of ≤200 ppm moisture and oxygen transmission over 5 years?
The film should be stored in a dry, low-humidity environment to preserve its barrier properties, as the 0.040 mm aluminum foil layer provides excellent moisture and oxygen barrier but can be compromised by prolonged exposure to high humidity. The ≤200 ppm transmission target over 5 years is achieved under proper storage conditions that prevent degradation of the adhesive and polymer layers.
This 113 μm aluminum laminated film offers exceptional barrier properties and forming depth suitable for pouch cell packaging, but requires precise temperature control during sealing and is offered in limited standard dimensions.
Positive
- Superior barrier performance against moisture and oxygen: Multi-layer structure with 0.040 mm aluminum foil core achieves ≤200 ppm moisture/oxygen transmission over 5 years, significantly extending pouch cell shelf life.
- Deep-drawing formability ≥5.0 mm: Film supports forming depth of at least 5.0 mm, allowing fabrication of deep pouch cell cavities without cracking or delamination.
Trade-offs
- Narrow heat-sealing temperature window: Effective sealing requires temperatures between 180–190°C (conventional) or up to 200°C (standard test), limiting compatibility with heat-sealing equipment that cannot precisely maintain this range.
- Standard dimensions require custom order for variation: Supplied in fixed 200 mm width × 10 m length rolls; any deviation in size necessitates custom specification via inquiry, adding lead time and minimum order considerations.
