What is Sun Film?

Sun film is a thin polyester film applied to the inside of car windows to reduce heat, block ultraviolet (UV) rays, and improve privacy.

It acts as a protective layer between sunlight and the car interior. Modern sun films can block a significant portion of solar heat and harmful UV radiation while still allowing visibility through the glass.

Sun films are widely used in cars to improve comfort, especially in countries with strong sunlight.

How Does Sun Film Work?

Sun films work by filtering sunlight and reducing the amount of heat and radiation entering the vehicle.
