Waterproof aluminum foil is a special aluminum foil material with the characteristics of waterproof, heat insulation and thermal insulation. It is mainly composed of aluminum foil and polyurethane foam. The aluminum foil layer can effectively isolate the entry and exit of air and moisture, while the polyurethane foam plays a role in thermal insulation to prevent temperature changes and moisture from affecting the material1. This material is widely used in many fields such as construction and cargo packaging due to its excellent performance.

The commonly used alloy numbers of waterproof aluminum foil mainly include 8011, 1100, 3003, etc.

Features of waterproof aluminum foil:

1. Excellent waterproof performance: The surface of the aluminum foil is specially coated or compositely treated to effectively block moisture penetration.
2. Strong corrosion resistance: Suitable for humid or acidic and alkaline environments.
3. Good barrier performance: Good shielding effect on oxygen, moisture and light.
4. Lightweight and durable: light weight, easy to transport and install, with high strength and durability.
5. Environmental protection: some aluminum foil products can be recycled to reduce the impact on the environment.
