Compared to single-layer ultra-thin aluminum foil, the composite structure of aluminum foil and kraft paper is more rigid and robust, making it less prone to tearing or damage during processing, transportation, and construction. Kraft paper, as a reinforcing substrate, effectively improves the tensile strength, tear resistance, and overall stiffness of the composite material, while providing excellent support and protection for the aluminum foil, resulting in better dimensional stability and processing adaptability.

Composite Aluminum Foil Structure
- Aluminum Foil
As the core functional layer, it provides high heat reflectivity and blocks moisture, air, and light.
- PE Layer
As the intermediate bonding and moisture-proof layer, it firmly bonds the aluminum foil to the kraft paper while improving the material’s waterproof and moisture-proof capabilities.
- Kraft Paper
Provides mechanical strength, stiffness, and tear resistance, making the composite material easier to cut, lay, and process.
Applications
Kraft paper-backed aluminum foil combines the high reflectivity, barrier properties, moisture resistance, and heat resistance of aluminum foil with the strength, stiffness, and ease of processing of kraft paper. Therefore, it is widely used in building insulation, heat insulation, packaging, industrial coating, and other fields.
- Building Insulation Materials
Can be used as a cladding material for glass wool, rock wool, mineral wool, and other insulation materials, helping to reduce moisture penetration and improve heat reflection performance.
- Roofing and Wall Insulation
Used in building roofing, wall, and ceiling systems, it can be used as a reflective insulation layer or a surface cladding for insulation materials.
- HVAC Ducts
Kraft paper composite aluminum foil can be used in air conditioning ducts and insulated duct systems, providing insulation, moisture protection, and some structural support.
- Packaging Materials
Utilizing the barrier properties of aluminum foil, it can be used in industrial packaging requiring moisture protection, light protection, and air barrier properties.
- Industrial Insulation
Used in insulation systems for pipes, equipment, storage tanks, and other industrial facilities.
- Composite Panels
Can be used as a surface layer for sandwich panels, insulation panels, and other functional composite materials.
