Five Tips on How to Choose PE Protection Film

PE (Polyethylene) is the simplest polymer organic compound in structure and the most widely used polymer material in the world today.PE protection film is made of special polyethylene (PE) plastic film as the base material, which is divided into high density polyethylene protection film, medium density polyethylene and low density polyethylene according to the density.The biggest advantage of PE protection film is that the products to be protected are not contaminated, corroded, scratched and protected from the original glossy surface during production, processing, transportation, storage and use. The biggest advantage of PE protection film is that the products to be protected are not polluted, corroded, scratched and protected from the original bright and shiny surface during production, processing, transportation, storage and use, thus improving the quality of the products and market competitiveness.

PE protection film is so widely used, so how to buy PE protection film? As a PE protection film supplier, we have compiled five tips on how to choose PE protection film and share them with you!

1. The degree of light transmission

This point is difficult to identify with the naked eye, it is best to use optical instruments to determine. There is a relatively simple method. Select PE protection film were cut a small piece of the computer desktop in the middle of the paste open, and then a new blank WORD document on the computer. Check the computer with film and no film area or different film area blank WORD document whitening degree (professional point of view called brightness). Compare them separately and you can choose the brightest material whose transmittance is the best protection film.

2. Haze

In a slightly dark room, open a fluorescent lamp, tear the PE protection film from the top and bottom of the release film and hold it in your hand between your eyes and the light. Look carefully to see if there is a layer of foggy stuff evenly distributed in the PE protection film. The more serious this foggy stuff is, the greater the fogginess and the worse the material is, and vice versa, the better it is. (Note that haze will affect the rate of transmission, but with the rate of transmission are two different concepts!)

3. Anti-scratch

PE protection film is scratch-resistant, scratch-proof is the most concerned about the issue. At present, the anti-scratch material on the market is basically the same (2-3H), and the performance is good, only the difference between anti-scratch and non-scratch. Test method is to use the hardness of 3H pencil, to 45 degrees angle 500G strength in PE protection film pressure push away 10 times, no scratch is considered up to 3H hardness requirements.

Another simple method is to use a slightly hard metal device or a newly cut nail to scrape the PE protection film with the usual strength of a stylus. If it is very easy to scratch, it is considered not scratch-proof, no scratch can be determined to have anti-scratch function.

4. Anti-fingerprint

In recent years, many products screen size is getting bigger and bigger, and more and more smart machines plus the application of capacitive screen (touch with your fingers and different from the old resistive screen to use the pen point to scratch).

5. Static electricity  

As LCD is a sensitive device afraid of static electricity, the less static electricity in the protection film, the better. Test method is to prepare the PE protection film to be tested (3 layers of material or two layers of material), smoke a cigarette and knock some ashes on the desktop. Or get some tiny scraps of paper on the desktop, then tear off the top layer of the PE protection film (for 3-layer material there is this step). Then tear off the silicone layer of the protection film, tear off this layer of PE protection film will immediately use the layer (silicone surface) to close to the ashes or confetti, to see whether the protection film will be these things will be adsorbed to the protection film of the silicone layer, the degree of adsorption is strong. The stronger it is, the higher the static electricity generated by this material, the worse the material is, and vice versa, the better it is.
