Hard to tear

After prolonged adhesion, the adhesive force may increase due to environmental factors (temperature, humidity, pollutants) and chemical reactions, making it difficult to remove, and potentially damaging the surface of the adhered object during the removal process.

Residual adhesive after peeling off

When removed after prolonged adhesion, residual adhesive often remains, not only affecting aesthetics but also requiring significant time and effort to clean, potentially damaging the surface of the object, which is contrary to the purpose of the protective film.

There are bubbles

Non-professional application of protective films can easily result in numerous bubbles, affecting aesthetics.

The adhesion material is limited

Common protective films often have soft adhesives with insufficient absorbency. Rough or matte surfaces can reduce the contact area between the protective film and the surface, dispersing the adhesive force and making it difficult to ensure a secure attachment of the protective film to the surface.

Corner lifting and falling off

Due to weak adhesion, uneven walls are prone to corner lifting and falling off, which prevents effective protection of the adhered object.
