    When buying a protective film, are you in a dilemma about which protective film to choose? Don't worry, today I will tell you what kind of protective film is a good protective film.

    There are many kinds of optical protective film materials. We will not give examples one by one here. Let's take a three-layer PET protective film as an example.

    The name of the three-layer PET protective film manufacturer is actually derived from its material PET. Our common PET high-pressure spray gun protective film has to undergo hardness treatment, so when judging the quality of the protective film, there are the following Kinds of standards:


    Medium sticky plain weave

    1. Light transmission effect. If the light transmission effect is better, it means that the material is better. The light transmission effect cannot be seen with your eyes, but a special instrument-3M photometer is needed.

    2. The surface hardening degree of the price of the protective film represents the degree of scratching of the protective film of this kind of stepless UV power supply curing equipment when it is scratched. The higher the degree of hardening, the higher the degree of scratch prevention.

    3. Take a look at the adsorption of the protective film. The faster the protective film discharges air, the stronger its adsorption capacity.

    4. Observe whether the protective film has crystal dots or rainbow patterns. If there are, the more the problem is, the greater the problem, so try not to choose a protective film with these problems.
