Laminated Aluminum Foil

Laminated foil, also known as laminated aluminum foil or composite aluminum foil, is a multi-layer composite material made by laminating aluminum foil with one or more functional materials (such as PET film, PE foam, kraft paper, bubble film, glass fiber cloth, etc.) through thermal lamination or adhesive process.

Compared with single-layer aluminum foil, laminated foil has significant advantages in barrier properties, heat reflection, structural strength and processing compatibility, and can simultaneously meet multiple requirements such as material lightweight, structural durability and functional integration. It is widely used in many engineering fields such as industrial packaging, building insulation, electronic and electrical protection, and thermal management systems.
