Driving in the summer, exposure to sunlight not only burns the driver's skin, but ultraviolet rays can also damage the car's interior, causing some leather parts to age. The rise in internal car temperature also increases the use of air conditioning, thus increasing fuel consumption. Therefore, applying a sun film is very necessary. However, there are many types of car films on the market currently, and their quality varies greatly. So when choosing a car film, it is important to have some identification methods.
1. Clarity: High-quality car film should have a clarity of over 6 meters at night, while inferior film has poor clarity, especially at night when the side and rear windows are unclear.
2. Texture: High-quality film feels thick and smooth, whereas inferior film feels thin and brittle, and easily wrinkles.
3. Color: The pigments in high-quality film are blended into the film itself, making them durable and resistant to color change. During application, even when scraped with a squeegee, they do not lose color. In contrast, the color in inferior film is in the adhesive layer. After peeling off the inner lining of the film, scratching it with your fingernail will cause the color to come off, and the area scratched will become transparent. During the application process, when the film is squeegeed, sometimes the color comes off by itself. Such films may change color within the same year, and the fading becomes more noticeable after a year.
4. Bubbles: When the plastic inner lining of the film is peeled off and then recombined, inferior film will bubble, whereas high-quality film remains intact.
5. Heat insulation: Heat insulation is an important indicator for sun film, and this is difficult to distinguish by just looking or feeling. A simple test method can be used for comparison: place a piece of glass with the car film on an iodine tungsten lamp. If you cannot feel any heat, it is a high-quality film. If you immediately feel the heat, it indicates that the heat insulation performance is problematic, meaning it is an inferior film.
