If the protective film is classified according to the scope of use, it can be mainly divided into the following different fields: metal product surface, plastic product surface, electronic product surface, coated metal product surface, sign product surface, automobile The surface of the product, the surface of the product of the profile, and the surface of other products.
This protective film should be relatively early on the market. The chemical name can be called polypropylene. Because it does not have any adsorption capacity, it needs to be glued to glue it, and after it is torn off, There will be traces of glue on the surface of the screen. If the time is long, it will cause corrosion to the screen, so it is basically no longer used.
Second, pvc material protective film:
The pvc protective film should be characterized by its soft texture and very convenient paste. However, this protective film is thicker in material and the transmittance is not very good. The whole screen will be blurred and uncovered. The back screen also leaves a mark, which changes over time and is therefore very short in life.
Third, pe material protective film:
This protective film is mainly LLDPE in the material, and the material is flexible and has certain stretchability. The normal thickness is maintained between 0.05mm and 0.15mm. The viscosity is determined according to the customer's requirements. In fact, the protective film of pe material can be mainly divided into: anilox film and electrostatic film.
Among them, the electrostatic film mainly uses static electricity to adsorb the adhesive force, and does not need to use any glue, so it is weak in viscosity, and is often used for surface protection of products such as electroplating; and the textured film has more mesh on the surface. The protective film has a good performance in breathability, and the effect of adhesion is also relatively beautiful. The main thing is that it is very flat and free of bubbles.
Fourth, opp material protective film:
If you look at the appearance from the outside, this protective film is similar to pet, and it is also relatively large in hardness and has certain flame retardant properties, but the effect of the whole paste is relatively poor, so the market is also relatively good. I can rarely see the use of this protective film.
In fact, there are many types of protective films that can be classified in use, such as common protective films for automobiles, plastic wraps for foods, protective films for digital products, and protective films for households. The materials are also from the previous pp, gradually The development of the current ar material on the market, the entire development process is still quite long, so it will be favored by the majority of the market.
