Any suggestions for choosing a protective film? Many products appearing on the market now have their own advantages. There are many products related to packaging materials, because packaging materials have many uses. In addition, the production technology of packaging products has been further improved. Protective film is also one of packaging materials, so the development of protective film is still possible. An understanding of the protective film is necessary. So what are the suggestions for choosing the protective film? Look at the mist (1) What do you think of the protective film's haze? The first thing to do is to check it when the monitor is turned off. The method is the same as above. After all the protective films are pasted layer by layer, the clearer the color of the image on the computer screen, the smaller the haze. The smaller the haze, the better the material. If you use a black test board, this method makes it easier to see the difference. (2) In a dark room, turn on the fluorescent light, tear off the upper and lower release paper of the Huizhou polyethylene protective film, and place your hand between your eyes and the light. Carefully observe whether there is a layer of evenly distributed mist on the Huizhou polyethylene protective film. This is the culprit affecting the smog. The more severe the fog, the worse the material. Otherwise, the better. (Please note that haze affects transmittance, but it and transmittance are two different concepts!) It is difficult to recognize the degree of light transmission with the naked eye. Use optical instruments to measure it. Another simpler method is to select the protective film, cut it into small pieces, place them in the middle of the computer desktop one by one, and then create a new blank WORD document on the computer, and check whether the blank WORD document is in the area where the film is attached. Or the degree of whitening of different film areas (brightness in professional terms). In contrast, you can choose the brightest material whose transmittance is a good protective film. Because the liquid crystal display is a sensitive device that is afraid of static electricity, the smaller the static electricity when the protective film is attached, the better. The test method is to prepare the polyethylene protective film to be tested (3 or 2 layers), hit some soot on the desktop, or make some small pieces of paper on the desktop, and then tear off the top layer of the polyethylene protective film (this step requires 3 layers) ), and then tear off the protective film of the silica gel layer. When the polyethylene protective film is removed, immediately approach the use layer of soot or paper scraps (silicone surface) to see if the protective film will absorb these substances on the silica gel layer of the protective film , And whether the degree of adsorption is strong. The stronger it is, the higher the static electricity generated by this material, the worse the material, and vice versa.
