If the protective film is classified according to the scope of use, it can be divided into the following different areas: metal product surface, plastic product surface, electronic product surface, coated metal product surface, sign product surface, automobile The surface of the product, the product surface of the profile and the surface of other products.

The application of the following four different materials of protective film:

1. Protective film made of pp material:

This protective film should have appeared earlier on the market. The chemical name can be called polypropylene, because it does not have any adsorption capacity, so it needs to be glued to it, and after tearing it off, There will still be traces of glue on the surface of the screen. If it takes a long time, it will also cause corrosion to the screen, so it is basically no longer used.

2. Protective film made of pvc material:

The big feature of pvc protective film should be that its texture is relatively soft and it is very convenient to paste. However, this protective film is relatively heavy in material and its light transmittance is not very good. The entire screen will be relatively fuzzy and peel off. The rear screen will also remain imprinted, because it will change over time, so the service life is very short.

3. Protective film made of pe material:

The material of this protective film is mainly LLDPE, and the material is flexible and has a certain degree of stretchability. The normal thickness is maintained between 0.05mm-0.15mm. The viscosity is determined according to customer requirements In fact, the protective film made of pe material can also be mainly divided into: anilox film and electrostatic film.

Among them, the electrostatic film mainly uses static electricity to absorb the adhesive force. It does not need any glue, so it is relatively weak in viscosity. It is often used for surface protection of products such as electroplating; while the anilox film has more meshes on the surface. This kind of protective film has good air permeability, and the adhesion effect is also more beautiful. The main thing is that it is very flat and does not have bubbles.

Four, opp material protective film:

If you observe from the appearance alone, this protective film is relatively similar to pet, and it is also relatively large in hardness, and has a certain flame retardant performance, but the effect of the entire paste is relatively poor, so it is also relatively in the market. It is rare to see the use of this protective film.

In fact, there are many kinds of protective films that can be classified in terms of use. For example, there are common protective films for automobiles, food preservation films, digital products, and household protective films. The materials are also gradually changed from the previous pp. Developed to the more popular ar material on the market, the whole development process is still relatively long, so it will be favored by the majority of the market.
