一种防指纹薄膜
By roughening the surface of the main film and adding an ink layer, the adhesion between the anti-fingerprint film and the main film is enhanced, solving the problem of the anti-fingerprint film falling off during hot and cold cycles, and achieving a longer service life and easy-to-clean anti-fingerprint effect.

AI Technical Summary
The traditional method of bonding anti-fingerprint film to the main film is prone to peeling, falling off, or bubbling during hot and cold cycles, affecting product lifespan and appearance.
By roughening the surface of the main film facing the anti-fingerprint film and setting an ink layer between the main film and the anti-fingerprint film, the adhesion between the two is enhanced, and the surface energy is reduced by using anti-fingerprint groups to form a mechanical interlocking structure.
It significantly enhances the adhesion between the anti-fingerprint film and the main film, preventing it from falling off, extending its service life, and achieving both anti-fingerprint and easy-to-clean effects.
