Aluminum Laminated Film (Toppan 113μm) for Lithium Pouch Cell Packaging

Description

Aluminum laminated film is a critical packaging material for lithium-ion pouch cells, serving as the outer protective layer that ensures cell integrity and long-term stability.

This multi-layer structure—typically composed of nylon, aluminum foil, adhesive layers, and polypropylene—offers excellent barrier performance against moisture and oxygen, along with strong heat-sealing capability.

It is widely used in pouch cell assembly and battery prototyping, where reliable sealing, chemical resistance, and mechanical durability are essential for consistent electrochemical performance.
