When buying protective film, do you have a dilemma about which kind of protective film to choose? Don't worry, today Xiaobian will tell you what characteristics of the protective film are good protective films.

There are many kinds of protective film materials. We won't give examples one by one here. Let's take the three-layer pet protective film as an example.

The name of three-layer pet protective film is actually derived from its material pet. Our common pet high-pressure spray gun protective film is subject to hardness treatment. Therefore, there are the following standards when measuring the quality of this kind of protective film:

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

2. The surface hardening degree of the protective film represents the scratch degree of the protective film of the stepless UV power curing equipment when it is scratched. If the hardening degree is higher, the scratch prevention degree is also higher.

3. Adsorb 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 lines. If so, the more represents the greater the problem, so try not to choose the protective film with these problems.
