What kind of flat plate needs film?

Different materials of the film, not only the screen has a material, but also the film is also different. The film has not changed much since its birth. Perhaps some consumers know that the earliest film was glued, not electrostatic adsorption like the current film. This kind of film is replaced by a new material in a very short time due to its poor material and large damage to the screen by the adsorption method. The second generation of early PET film products is PET film. This kind of film is now available in the market, but this kind of film is rarely used as a screen film, instead, it is mainly used to wrap the whole film of the whole machine. This kind of film material is similar to the plastic wrap used in the home, but it is slightly thicker than the plastic wrap and has certain ductility. The third generation of film products is now more common on the market. At present, it is mainly divided into three materials, PET, ARM and PVC.
