Core Advantages of Aluminum Foil Laminated Kraft Paper Zero-Permeability Moisture Barrier The aluminum foil layer (0.006-0.05mm) forms a dense metal barrier with a near-zero water vapor transmission rate. Comparative experiments have shown that in a 90% humidity environment, the corrosion rate of electronic components packaged in laminated kraft paper is 98% lower than that of conventional PE film packaging, significantly extending the storage life of precision instruments, food, and pharmaceuticals.

Dynamic Heat Reflection Insulation The aluminum foil has a reflectivity of up to 97%, effectively blocking infrared radiation heat. Industrial tests show that pipe insulation using 150g/m² kraft paper + 0.03mm aluminum foil reduces the cooling rate by 40% compared to traditional glass wool materials, making it suitable for cold chain logistics boxes and thermal protection of industrial equipment.

Tear Resistance Mechanical Architecture

Substrate Mechanical Strengthening Model: Puncture Resistance (N) = 0.32 × Kraft Paper Weight (g/m²) + 6.8 × Aluminum Foil Thickness (mm)
