This laminated film is engineered for pouch lithium battery packaging and demands specific handling to maintain barrier integrity. The inner CPP layer requires heat-seal stability and electrolyte corrosion resistance, while the aluminum barrier necessitates protection from physical damage and moisture exposure.

• Heat-Seal Processing: The inner CPP layer must be heat-sealed at controlled temperatures to achieve reliable hermetic seals without delamination.
• Electrolyte Compatibility: The CPP layer is formulated to resist corrosion from lithium battery electrolytes; avoid contact with incompatible solvents that may degrade the seal layer.
• Moisture Barrier: The aluminum foil layer provides critical moisture and oxygen barrier; store in a dry, low-humidity environment to prevent degradation.
• Mechanical Handling: Use clean, smooth tools and avoid sharp edges during processing to prevent scratches and punctures on the film surface.
• Storage Conditions: Store at room temperature in sealed packaging away from direct sunlight to preserve formability and barrier properties.

This 91μm DNP aluminum-laminated film delivers robust moisture-oxygen barrier and broad process compatibility for pouch cell assembly, though its adhesive coating weight tolerance introduces bond-line variability and standard roll dimensions require custom ordering for non-standard sizes.

Positive

• High barrier performance extends cycle life: The soft aluminum foil core (35 μm) combined with the inner CPP layer provides exceptional moisture and oxygen permeation resistance, directly improving battery longevity in pouch cell applications.
• Excellent formability and wide heat-seal window: The film withstands deep-drawing, edge folding, and stamping without cracking or delamination, while the inner CPP layer maintains high seal-edge strength across a broad temperature range, reducing leakage risk in production.

Trade-offs

• Adhesive coating weight variability: The carbon-black adhesive layer is specified at 3.8 g/m² with a positive tolerance of +1.5 g/m², meaning actual coating weight can vary up to 5.3 g/m², which may introduce inconsistencies in composite bond strength across the roll.
• Non-standard dimensions require custom order: The film is supplied as a 200 mm × 10 m roll; any deviation from this dimension necessitates a custom inquiry, adding lead time and minimum order considerations for lab-scale or non-standard cell designs.
