The specifications and models of aluminum foil are usually determined by factors such as its thickness, width, alloy and purpose. The following are some common aluminum foil specifications and models.

1. Common aluminum foil specifications:
Trwch: usually in microns (um) or millimeters (mm), such as 0.01mm or 10um.
Lled: usually in millimeters, such as 300mm or 500mm.
Length: Typically supplied in rolls, length varies based on use and demand.

Alloy of aluminum foil: Aluminum foil can be made of different aluminum alloys, such as pure aluminum (aloi 1050,1060,1100,1235), aluminum-manganese alloy (aloi 3003,3004,3105), aluminum-silicon alloy (aloi 8011,8021,8079), etc.
The choice of alloy depends on the required strength, corrosion resistance and other properties.

3. Packaging aluminum foil: Aluminum foil is usually used for packaging and preserving food. Common specifications include 15um thickness and 30cm width.

4. Kitchen aluminum foil: Aluminum foil is commonly used for baking, cooking and packaging, and generally has moderate thickness and width.

5. Medical aluminum foil: Aluminum foil used for medical equipment and pharmaceutical packaging, with special hygiene and quality requirements.

6. Aluminum foil for the electronics industry: Aluminum foil used for electronic components and cable shielding, usually with higher purity and specific alloys.

7. Aluminum foil for air conditioning and refrigeration equipment: Aluminum foil used in air conditioners, refrigeration equipment and automobile air conditioners usually requires specific heat conduction properties and corrosion resistance.

8. Construction and decorative aluminum foil: Aluminum foil used for construction materials and decoration, usually with different coatings and surface treatments.

The specifications and models of aluminum foil will vary depending on the manufacturer and region. HWPFP can supply according to the product specifications required by customers.
