ALF-113 Aluminium Laminated Film

Aluminium laminated film is a critical barrier and sealing material used to fabricate lithium-ion pouch cell cases. It combines high moisture/oxygen barrier performance with electrical insulation and thermoformability, helping protect sensitive electrode and electrolyte chemistries during battery testing and long-term storage.

Construction & Working Mechanism

This 113 µm pouch-film structure is engineered as a multilayer laminate (outside shiny → inside mat):

• Polyamide (PA) outer layer (~0.025 mm): mechanical strength, puncture resistance, and form stability
• Adhesive tie layers: promote durable bonding between polymers and aluminium
• Aluminium foil core (~0.040 mm): primary barrier against H₂O/O₂ ingress and electrolyte vapour loss
• Polypropylene (PP) inner layer (~0.040 mm): heat-sealable surface and chemical resistance to common battery electrolytes
  
  

Key Specifications (Typical)

• Thickness: 113 µm | Width: 400 mm | Length: 10 m (roll)
• Hot sealing condition: 180–190 °C
• Moulding (forming) depth: ≥ 5.0 mm
• Electrical insulation: Good
• Barrier performance: moisture vapour / O₂ transmission commonly specified to support long shelf-life expectations
• Surface quality: mat inner finish for consistent sealing behaviour
  
  

Compatibility & Typical Use

Designed for laboratory and pilot-scale pouch cell fabrication using pouch forming dies and heat sealers. Suitable for assembling single-layer and stacked pouch cells for electrochemistry and battery testing workflows.

Applications

• R&D pouch cells for cathode/anode screening, electrolyte optimisation, and formation cycling
• Prototype pouch packaging for lithium-ion and sodium-ion cell development
• Seal integrity studies, gas generation assessment, and abuse-testing preparation
