Q:What to do if the adhesion of the PE protective film is too high?
Recently, the adhesion of PE protective film is determined by the thickness of slica gel. Not long ago, when making protective film for the screen of VDOO mobile phone, the company had the same problem. High adhesion means high thickness. When the whether is hot,the slica gel will expand when heated and contract when cooled making it look like the screen is sweating,which is call overflow for short in jargon. Therefore, make sure the adhesion is not too high, otherwise it will be difficult to tear the film down. The VDOO company did many experiments when designed the film and finally found the appropriate data of thickness. Besides, taking the thickness into consideration, the purposes of flatness, high resisitance to scratches and high clarity also achieved.
Q:How to remove the protective film on the door in a quick way?
Tear it off quickly.
Q:How to peel the protective film from the screen of mobile phone without damaging the screen?
If the film you used is hard type, you can stick the upside of the film using scotch tape. And then prying it up from a corner and peeling it from the screen by drawing the scotch tape. And it's done. If it's soft and thin type,
Q:What kind of printing press is needed to cover decorative protective film?
During the processing of protective film, film mulching machine must be used in film mulching. And gravure rotary press can be used in printing the protective film.
Q:What's the reason why watermarks are easy to appear on protective film of high adhesion?
NOTE: Standard protective film is anti-static. You can't feel it adhesive by hands. It's the only choice of high-class digital camera and digital vidicon. Some protective films on the market is very sticky because it's just a layer of plastic film coated with glue. There may be bubbles or watermarks on the screen after you cover it on the screen. The display effect will be very bad. And this kind of film is very difficult to remove. It's even more difficult to clean up the glue. Remember it: if you really cherish your cell phone, digital camera or digital vidicon,NEVER use this kind of film on it!
Q:What are the differences between a LCD protective film for laptop and a protective film for mobile phone ?
The functions of a laptop LCD protective film: 1. Ordinary films: Ordinary films only protect the screen from dust and scratch. This kind of films is commonly used and classified into two types--scratch-resistant(a bit more expensive) and non-scratch-resistant. 2. Functional films: this kind of films has better properties of scratch-resistant properties that can be classified into: A. Anti-reflection films, preventing the reflection of light on the screen, work well on some glossy display. Correspondingly they are more expensive than ordinary ones. B. Anti-ultraviolet-radiation films, protecting your eyes, have different technical content. This type of films is colored film --purple or green. But there's no need to mind the color because it's actually transparent when it cover the screen. The color a41 won't show up. And it won't affect the color displayed on the screen. C. Privacy-protective films. After coated with this kind of films, only looking at the screen head-on, or from no more than 30 degrees to sides, people can see the content shown on it clearly. And this kind of films is the most expensive among all.
Q:If the keyboard protective film is too big, do I need to cut it?
No need to cut it. You can just use the whole film to cover the keyboard.
Q:How about the electrostatic adsorptive function of PE protective film ?
1. Corona treatment is used in the process of the making of PE protective film, increasing the surface area of the film and making it static to meet the need of the following gluing. It's conducive to the combination of glue and film this way. 2. There's no such PE anti-static protective film with glue itself has adsorption function. Multi-layer film blowing machine can make such product at one time.
Q:What kinds of materials is the protective film made from?
According to material quality, it can be made from common materials including PET, OPP (PP), PVC and PE.
Q:Is it necessary to use PET high-temperature-resistant protective film in lithium battery?
Generally speaking, PET high-temperature-resistant film is used to cover the surface of the battery core before the core is dried. The main function is to protect the surface of the battery core from scratches and the liquid in the battery from corrosion. The film is resistant to high temperature bacause the battery core needs to be dried at temperature of 75-85 degrees. Some PET protective film may be out of shape at that temperature. Meanwhile, there is certain requirement for the adhesion of the protective film. It can't be too sticky. Otherwise the packaging film may be torn down when you dismantle the battery. In addition, it must be ensured that the protective film won't fall off during the following processing of producing the battery core.
