The traditional screen protection film has a plurality of defects and is not beneficial to the automatic operation of screen processing manufacturers. If traditional protection film surface is the plane, when piling up together, closely laminating between the protection film forms vacuum negative pressure, and the manipulator washes the dish when snatching the protection film, very easily produces the company, should snatch a slice, and the result can snatch two even multichips. In addition, the traditional antistatic protective film lacks sufficient antistatic performance, and the film that the manipulator grabbed and taken out produces deformation because of electrostatic action, leads to laminating inaccurate or dislocation. The above problems seriously affect the efficiency of the automation operation.
