153μm Aluminum Laminated Film Laminated Composite Foil Material for Pouch Cell Battery Case

Product Overview

This high-performance 153μm aluminum laminated film is engineered specifically as a premium encapsulation material for lithium-ion pouch cell battery outer packaging, advanced energy storage systems, and solid-state battery R&D. Built upon a sophisticated multi-layer composite structure, the material combines high-purity aluminum foil with specialized protective polyamide/polyester surface films and chemically resistant polypropylene inner sealing layers. The design delivers maximum barrier protection against moisture ingression, electrolyte leakage, and environmental degradation, providing peace of mind for high-density battery cell manufacturing.

Designed for demanding industrial cell production and academic research facilities alike, this flexible packaging composite excels in deep-drawing cold forming processes. The material demonstrates outstanding stretchability without pinhole formation, edge cracking, or layer separation, allowing battery manufacturers to produce deep-cavity pouch shells with precise dimensional consistency. Target sectors include automotive electric vehicle (EV) battery pack fabrication, grid-scale renewable energy storage modules, consumer electronics, aerospace power systems, and high-drain cordless equipment.

Built to perform under harsh chemical and thermal conditions, the packaging material guarantees exceptional long-term hermetic seal integrity. Its internal modified polypropylene layer offers proven chemical resistance against aggressive carbonate solvents and dissolved lithium salts such as LiPF6. Backed by rigorous quality control standards, including zero-defect visual verification and high inter-layer peel strength, this unit delivers consistent operational reliability for cell fabrication workflows.

Key Features

• Multi-Layer Composite Architecture: Features a optimized stack-up including a 40μm high-barrier aluminum core combined with outer PET/ONy layers and inner PPa/PP sealant films for maximum mechanical toughness and zero moisture permeability.
• Superior Electrolyte Chemical Resistance: Specially formulated inner polypropylene adhesive layer resists chemical attack from organic carbonate solvents and lithium salts, maintaining high bond strength (typical values of 12.9 to 13.9 N/15mm) after prolonged electrolyte exposure.
• Exceptional Inter-Layer Bond Strength: Delivers outstanding layer-to-layer peel resistance exceeding 50 N/15mm nominal requirements, with test averages reaching 121 to 125 N/15mm to eliminate any risk of delamination over extended service life.
• Robust Heat-Sealing Integrity: High thermal stability of the inner polypropylene structure ensures durable heat seals, achieving room-temperature bond strength up to 17.1 N/15mm and maintaining thermal seal strength above 4.7 N/15mm at elevated temperatures (120°C).
• High-Ductility Deep Drawing Capability: Engineered for cold-forming pouch shell fabrication, allowing uniform elongation and deep pocket stamping without localized necking, micro-cracking, or pinhole failure.
• Zero-Defect Surface Quality: Subjected to 100% optical quality inspection ensuring freedom from pinholes, cracks, dust, grease, foreign particles (≥0.5mm), dents, and excessive PP fish-scale patterns.
• Precision Roll Winding: Manufactured with tight lateral winding tolerances within ±1.0mm deviation across standard 400mm widths, ensuring continuous, jam-free feeding into automated battery pouch forming and sealing machinery.
