Metal Foils
Advanced Surface Treatment Solutions for Metal-Polymer Laminates & Decorative Packaging
Leveraging plasma activation, chemical functionalization, and nanoscale etching technologies, we engineer surface treatments to achieve critical bond strength in:
Barrier Packaging – Prevent electrolyte-induced delamination in aluminum-polymer battery pouches (e.g., Li-ion cell encapsulation)
Decorative Foils – Enhance metallized paper adhesion for luxury flexible packaging without coating defects
Functional Laminates – Optimize interlayer bonding in multi-material structures (e.g., Al/Gf/PP composites for automotive)
