Through selecting the third lug with the height range, the lug formed by the wear-resistant layer is fine and smooth, comfortable to touch and good in wear resistance, and the practicability of the car cover film is further improved. When the height of the third bump is smaller than 3nm, the third bump is too small, the surface of the wear-resistant layer is smoother, and the wear resistance is further reduced; when the height of the third bump is larger than 10nm, the friction force is too large, the hand feeling is rough, and the experience of a user is affected.

Preferably, a plurality of glue points are arranged on one surface of the pressure-sensitive adhesive layer, which is far away from the polyurethane, and the glue points are abutted with the second release layer.

Preferably, by setting the glue points, when the car cover film is attached to the car, pressure is applied in the attaching process to enable the glue points to diffuse, and then the car cover film is tightly attached to the surface of the car.

The first release layer and the second release layer are films made of PET or PE. The film prepared by PET or PE has better release effect.

In summary, the present application includes at least one of the following beneficial technical effects:

1. the first bump is embedded with the first slow groove to enable the wear-resistant layer to be tightly connected with the polyurethane layer, and the second bump is embedded with the second slow groove to enable the pressure-sensitive adhesive layer to be tightly connected with the polyurethane layer, so that the layer structure of the car cover film is tightly connected, the flexibility of the car cover film is improved, the abrasion or tearing phenomenon of the car cover film is reduced, and the practicability of the car cover film is improved;

2. through setting up the third lug, make its wearing layer's surface have dull polish feel, increase its frictional force, reduce the phenomenon such as wearing and tearing appear in the car clothing membrane in the use.
