How To Buy PE Protective Film?

May. 25, 2021

PE protective film is so widely used, so how to buy PE protective film, has become a matter of urgency, the PE protective film manufacturer decided to buy five kinds of PE protective film technology today, to share with you! As follows.

First: look at the light penetration

This is difficult to identify with the naked eye, it is best to use optical instruments to determine, there is a relatively simple method, is to choose PE protective film in the middle of a small piece of computer desktop a cut and paste, and then create a blank WORD document on the computer to check the computer with film, no film or other film area (professional point called brightness) of the degree of whitening WORD document blank. In contrast, you can choose the brightest material, and its transparency is the best protective film.

Second: look at the haze

1. PE protective film haze how to see? The first thing to do is to turn off the monitor. The method is the same as above. After pasting the protective film in turn, the clearer the color of the computer screen, the smaller the haze. The smaller the haze, the better the material. This method makes it easier to see the difference if you use a black test panel.

2. In a slightly dark room, turn on the fluorescent light, remove the PE protective film from the film up and down with your hand, put it between your eyes and the light with your hand, and take a closer look to see if there is a thin layer of fog in it. The PE protective film is evenly distributed and is the culprit of the haze. The more severe the haze, the worse the material is. Conversely, it means better. (Please note that haze affects permeability, but transmittance is a different concept!


Third: Look at static electricity

Since LCD devices are sensitive to static electricity, they should be as low as possible when there is a protective film applied. The test method is to prepare the PE protective film to be tested (3 layers or 2 layers) and smoke to hit the soot on the desktop.

or get some confetti on the desktop, then peel off the top protective film of the PE protective film (this step is a 3-layer material), then tear off the protective layer of silicone, then tear off the layer of PE protection When using protective film, immediately use the layer (silicone surface) to bring it close to the soot or confetti, and observe whether the protective film will adsorb these substances to the silicone layer of the protective film and whether the degree of adsorption is strong.


Fourth: look at the catch point

1. PE protective film is scratch-resistant, anti-scratch is everyone's current concern, the current market scratch-resistant materials are basically similar (2-3H), and good performance, only scratch-resistant and not scratch-resistant. The test method is to use a pencil with a hardness of 3H to push the PE protective film 10 times with a force of 500 degrees at an angle of 45 degrees. The scratch-free condition is considered as high as 3H.

2. There is a simple method is to use a slightly hard metal device or a freshly cut nail to scratch on the PE protective film using the way you usually scratch with a stylus, if it is easy to scratch then it is not scratch resistant, without scratching it can be determined that it has a scratch-resistant function.


Fifth: anti-fingerprint

In recent years, many product screens have become larger, and more and more smartphones are using capacitive touch screens (touching with your finger instead of the old resistive screens). PE protective films are increasingly needed to have fingerprint resistance.
