Abstract
A method improves the property of films including a release film and a protective film. After separating from the release film, the protective film is bonded with a TAC (Triacetyl Cellulose) film and then processed by coating, such as with an anti-reflecting coating, an anti-glaring coating and a surface hardening treatment, and by drying in an oven. The protective film is separated from the TAC film. The waste of material, which resulted from cracks, snaps and bends of the film, is avoided in the process. Furthermore, practice costs are low, and additional expensive apparatus or treatment are not necessary for a simplified procedure of the method.
