A protective film for aluminum coils is a thin plastic film with a light adhesive. It protects the aluminum surface from scratches, dirt, oxidation, and environmental factors during manufacturing, transportation, and storage.

1. Features of Protective Film for Aluminum Coils

Material: PE (Polyethylene) plastic, known for its good elasticity.
Thickness: Ranges from 30 to 120 micrometers, suitable for the thinness of aluminum coils.
Colors: Available in transparent, milky white, blue, or black and white for easy identification.
Adhesion: Just sticky enough to hold firmly to the aluminum surface but can still be easily peeled off without leaving residue.
Key Functions: Resists scratches, dirt, and water, while also offering good heat and light chemical resistance.

2. Benefits of Protective Film for Aluminum Coils

Protects the aluminum surface from scratches and dents during manufacturing and transport.
Prevents dust, grease, and chemicals from affecting the aluminum surface quality.
Reduces oxidation, helping the aluminum stay shiny before it’s put into use.
Allows the aluminum coil to be unrolled and re-rolled easily without scratching the surface.

3. Applications of Protective Film for Aluminum Coils

Construction: Protects aluminum coils used to make aluminum composite panels, roofing sheets, and aluminum doors.
Automotive: Applied to aluminum coils used in the production of automotive components.
Packaging and Decoration: Protects the surface of anodized and color-printed aluminum.
Electronics Manufacturing: Protects aluminum used for electronic device casings.

The protective film helps ensure the quality of aluminum coils before they reach the end user.
