Clarity: Regardless of the color of the film, high-quality film should be able to clearly see objects 6 meters away at night, while low-quality film will have a hazy feeling.
Hand feel: High quality film has a thick and smooth feel to the touch, while low-quality film has a thin and brittle hand feel, which is prone to wrinkling.
Color: The pigment of the high-quality film is uniformly integrated into the film, which is not easy to change color. During the pasting process, it will not fade even after being scraped by a scraper. The color of the inferior film is in the adhesive that acts as a bonding agent. After tearing off the inner lining of the car film and scraping it with a nail, the color will peel off.
Bubble: When the plastic lining of the car film is torn off and then recombined, inferior film will bubble, while high-quality film will remain intact after being recombined.
Thermal insulation: The thermal insulation performance can be compared through a simple testing method: placing a piece of glass attached to the car film on an iodine tungsten lamp, and using high-quality film without feeling any heat with your hands.
Safety: The latest generation of glass protective films has taken strong impact resistance as one of the performance indicators. In general, splashes, intentionally infringing bricks or iron bars in accidents are difficult to penetrate the glass protected by the safety film.
