Embodiment Construction
[0013] Specific embodiments of the present invention will be described below.
[0014] The protective film material of the present invention can use raw materials such as high-density polyethylene, low-density polyethylene, linear low-density polyethylene, polypropylene, etc., and can be mixed in any proportion or used as 100% pure material. Inorganic substances or antistatic agents can be added to the raw materials, and the antistatic coating can also be applied to the surface of the protective film by surface coating. The type of the antistatic agent is not limited in this case, as long as it can be added to the above-mentioned materials, for example, various surfactants such as cationic, anionic, and nonionic can be used; it is a non-interface Active permanent antistatic agent, or use conductive fillers.
[0015] The manufacturing method of the protective film is to use film blowing equipment, extruding equipment, or laminating equipment to make a roll film in a dust-free ...

The invention discloses a protective film of a two-dimensional display and a manufacture method of the protective film. The protective film has the characteristics of thickness of 0.03-0.20mm, smooth and soft surface, haze of less than 30 percent, light transmittance of more than 85 percent, powder generating amount of less than 0.5 percent per unit area, and cleanness that not more than 7 powder particles with particle size 0.5mu m-5.0mu m (the cleanness is below 1000 level), not more than 1000 powder particles with particle size of below 0.5mu m and no powder particle with particle size of more than 5.0mu m. The protective film is a soft transparent or semi-transparent film made by mixing raw materials such as high density polyethylene, low density polyethylene, linear low density polyethylene or polypropylene with other materials, a long-acting antistatic agent of a non.-interface activity component can be added in the raw materials, or an antistatic coating is coated on the surface of the raw materials. The soft film can be tightly attached on the display part of the display. An adhesion fixing means is adopted in end corners of the soft film, so that the protective film is fixed on a frame around a glass substrate.
Description
technical field [0001] The invention relates to a protective film for a flat panel display or a glass substrate and a manufacturing method thereof. The protective film is mainly used as a barrier package for products to prevent the products from being dirty or scratched during circulation or transportation. Background technique [0002] The glass substrates used in flat-panel displays, such as liquid crystal displays, plasma displays, light-emitting diode displays, touch displays, etc., have a Mohs hardness of about 2H, which is different from the high-hardness glass used in traditional cathode ray tube displays. Therefore, In the process of circulation, transportation or storage, it is easy to cause dirt, friction and scratches due to the adhesion of foreign matter or dust, so it is necessary to use a protective film as a barrier packaging. [0003] In the known technology, the protective film is made of plastic materials such as PE or PET, which can be divided into hard (s...
