The first trick: Observe the appearance and transmittance

First, observe the appearance of the car window film. The surface of the high-quality film is smooth and delicate, the color is uniform, and there are no obvious impurities and defects. The surface of the inferior film is often not smooth enough, there is an obvious sense of granularity, uneven color, and even bubbles and impurities. If you find that there are obvious problems with the appearance of the window film, it is best not to choose this film.

In addition, no matter how deep the color of the car membrane, there must be clarity that does not affect the driving field of view, the higher the transmittance, the higher the brightness in the car. According to the national regulations, the light transmittance of the front file film needs to reach 70%.

Most of the inferior film substrate is cheap, with cheap prices to attract consumers, in fact, glass film a penny a penny goods, in order to health should not choose lower than the market price of glass film. There are also some inferior film is a shoddy fake film, which requires the owner to carefully ask when buying the glass film to judge the authenticity.

Tip 4: Listen to the voice

High quality film has better sound insulation effect, while poor quality film is often noisy. You can close the window after applying the film and listen for any noticeable noise. If you hear obvious noise, it means that there is a problem with the quality of this film and it needs to be replaced in time.

At the same time, we also need to understand what harm the inferior film will bring to us. The harm of poor quality film mainly has the following points:

1. No heat insulation: The heat insulation effect of the inferior film is poor, and it can not effectively block the sun’s heat, resulting in an increase in the temperature of the car and affecting the driving comfort.

2. Odor: The material composition of the inferior film is poor, and harmful substances such as adhesives are added. After sunlight exposure, it is easy to decompose and emit a pungent odor, which affects the health of the occupants of the car.

3. Affect the line of sight: poor quality film is easy to bubble, decompose, produce light distortion, affect the driver’s line of sight, easy to cause traffic accidents.

4. Harmful to human body: poor quality film contains formaldehyde, benzene and other harmful substances, long-term inhalation is easy to affect human health, and even induce chronic poisoning and respiratory system and other diseases.

5. Accelerate the aging of vehicle parts: the inferior film does not have any protection, and the interior decoration, interior decoration, and plastic parts that are exposed to the sun for a long time will accelerate the aging.

Therefore, in order to protect the health and driving safety of the occupants of the car, it is recommended to choose a regular brand and quality of car film. At the time of purchase, it can be judged from the appearance, smell, after-sales, sound and other aspects to avoid the purchase of inferior film.
