1, observe the clarity
The clarity of the car film is an important indicator to ensure the safety of driving. Regardless of the color of the film, please pay attention to whether the outer contour of the article is clear through the film glass; the inferior film may have a misty feeling or even cause the outer contour of the article to be deformed; the high-quality film has a very high definition regardless of the color depth. There will be no foggy phenomenon with unclear vision.
2, touch by hand
The feel of the high-quality film touched by hand is thick and smooth, while the inferior film is different, and the hand feels thin and brittle.
3, see the color
The high-quality film pigment is uniformly blended in the film, durable, not easy to change color, and will not be discolored by the scraper in the process of sticking; the color of the inferior film is in the adhesive glue, tearing the car After lining the film, scrape it with your nails and the color will fall off.
4, smell smell
When the high-quality glass film tears the lining, there is basically no smell; when the inferior film tears the lining, it will emit a very pungent smell, its quality is not good and the performance of the mounting glue used is not stable enough.
5, check if blistering
When the plastic lining of the film is torn off, and then recombined, the inferior film will foam, and the high-quality film will be as good as before.
6, inspection of scratch resistance
The high-quality film surface has a layer of anti-scratch layer, which can protect the film surface from being scratched under normal use; if there is no anti-scratch layer protection, the film will be scratched by the tool when the film is applied. Reduced clarity will also seriously affect the life of the film. You can use your nails to scrape back and forth on the glass film (non-lining). If you can easily hang the scratches, it must not be a good quality glass film.

It is definitely not the glass film imported from the United States. Later, it is very important that there is no English address on the car box. If there is any indication, please check the Internet. If the brand does not even have a formal English website, then it must not be a glass film product imported from the United States.
