It is normal to have air bubbles after the car film is applied, for the following reasons:

Dust impurity

The glass surface is not properly cleaned and dust is attached. As the adhesion strength of the film increases, pressure appears around sand or dust, and foam is generated. The car needs to be carefully cleaned and wiped before pasting.

Inferior membrane

The film structure of inferior automobile film is rough, and bubbles and wavy lines are easy to appear, and the inferior film is easy to degum after pasting, and hollow bubbles will also appear after degumming. It is best to choose a professional car film brand with good quality when pasting.

Car window film pasting

Autotintfilm is to stick a film-like object on the front and rear windshield, side window and skylight of the vehicle. This kind of film-like object is also called solar film or thermal insulation film. The function of car film is mainly to block ultraviolet rays, block part of heat, prevent damage caused by glass splashing and prevent glare. At the same time, according to the unidirectional perspective performance of the solar film, the purpose of protecting personal privacy is achieved. In addition, the car film can also reduce the damage of ultraviolet radiation to the goods and people in the car, reduce the temperature in the car through physical reflection, reduce the use of automobile air conditioning and reduce fuel consumption.

The correct operation method of car film is as follows

1. First, measure the size of the window and cut the film according to the measured size;

2. Clean the dirt on the glass surface without leaving water stains;

3. Before pasting the film on the car window, tear off the car film, spray water evenly on the effective pasting surface, and then stick it on the glass to fix it;

4. In order to reduce the appearance of small bubbles, it is necessary to evenly smooth the car film from the middle position to both sides of the glass with water;

5. Use a hot air gun to bake and reshape the car film. At this time, the temperature should not be too high, and the appropriate temperature should be mastered;

6. Lift the adhesive film, spray the installation liquid, and then scrape the surface of the adhesive film with a scraper. The purpose of this is to drive away small bubbles.

The function of car film

Increase the aesthetic feeling: When many people film the car, the most important thing is to increase the aesthetic feeling of the car after filming, or to personalize the film according to their own preferences;

Increase private space: because the car film is generally used to look outside the car, not inside the car, leaving a good private space for the car;

Safety and explosion-proof: the car film can also improve the safety of the car, because the car material has the functions of tear resistance and puncture resistance, and the adhesive layer of the film can reduce the damage to passengers after the glass is broken;

Heat insulation and sun protection: the film can also block the heat generated by infrared rays, and can also block the damage of ultraviolet rays to skin and automobile parts;

Anti-glare: if there is no film, the car will produce glare after encountering strong light, which is prone to accidents. However, with the film, accidents caused by glare can be reduced.
