High-Performance Laminated Foil for Packaging and Insulation
Laminated aluminum foil is a multi-layer material designed to offer strong barrier protection, high durability, and excellent heat resistance. It is widely used in food packaging, cable insulation, HVAC ducts, pharmaceuticals, and industrial sealing.
Laminated Aluminium Foil
Laminated aluminum foil combines a thin aluminium layer with other materials such as PET, PE, PVC, or paper. These layers are bonded together by adhesives or extrusion coating. The purpose is to improve strength, moisture resistance, heat sealing, and printability.
Main Benefits
- Strong barrier against moisture, oxygen, and light
- Durable and resistant to tearing
- Easy to shape and seal
- Excellent for long-life packaging
- Stable under high temperatures
- Lightweight and economical
