Aluminum Foil – Flexible Barrier for Packaging, Insulation & Industrial Use

We produce aluminum foil in jumbo rolls and slit coils for packaging, cable shielding, HVAC insulation, and household use. Soft and hard tempers with multiple alloys available.

What Is Aluminum Foil?

Aluminum foil is a thin, flexible sheet of aluminum known for its excellent barrier protection, thermal conductivity, formability, and corrosion resistance. It is rolled into ultra-thin gauges to serve a wide range of industrial and consumer uses.

Common Types:

Household Foil – cooking, freezing, food wrap

Packaging Foil – yogurt lids, medicine blisters, flexible pouches

HVAC Foil – duct insulation and lining

Cable Foil – EMI/RFI shielding

Battery Foil – for lithium-ion cathode/anode use (upon request)

Performance Characteristics and Applications of Aluminum Foil

I. Performance Characteristics

Physical Properties

1.1 Lightweight and Flexible: With a thickness of only 0.006–0.2 mm, it is lightweight and highly malleable, allowing it to be molded into complex shapes.

1.2 High Thermal Conductivity: With a thermal conductivity of up to 237 W/m·Kelvin, it can quickly and evenly transfer heat.

1.3 Heat Reflectivity: High reflectivity to light and heat, suitable for extreme temperature environments (-196℃ to 300℃).

Chemical and Protective Properties

2.1 Strong Barrier Properties: Completely blocks moisture, oxygen, light, and bacteria, with a significant antibacterial effect.

2.2 Oxidation Resistance: A dense oxide film on the surface prevents corrosion; it is non-toxic and odorless, and can directly contact food.

2.3 Excellent Sealing Properties: Puncture-resistant and tear-resistant, effectively protecting contents from external contamination.

Environmental and Economic Benefits

3.1 Recyclability: Aluminum is reusable, with low energy consumption and environmental friendliness.

3.2 Lightweight: Weighing less than one-third of steel, reducing transportation and usage costs.

II. Main Applications

Packaging
1.1 Food Packaging: Used for chocolate, cooked foods, etc., providing moisture and oxygen barrier for freshness preservation and supporting direct heating.

1.2 Pharmaceutical Packaging: Blister packaging provides moisture and light protection, ensuring drug stability; PTP aluminum foil is portable and hygienic.

Construction and Industry
2.1 Energy-Saving Building Materials: Roof reflective films reduce temperature by 8–15℃; wall insulation layers improve energy efficiency by 30%.

2.2 Electronic Equipment: Carbon-coated aluminum foil on the positive and negative electrodes of lithium batteries extends battery life by 15%; electromagnetic shielding materials protect precision components.

Special Applications
3.1 Aerospace: Ultra-thin aluminum foil (0.03 mm) is used for heat protection, withstanding extreme temperatures.

3.2 Household and Cooking: Used in refrigerators to wrap food to prevent deformation; provides even heating in ovens/steamers.

Aluminum foil, with its comprehensive properties, has become a core material in packaging, construction, electronics, and other fields, combining functionality and sustainability.
