How to Identify High-Quality Window Film?

1. Clarity: Regardless of the color intensity, high-quality window film should provide clear visibility at night, with a visibility distance of more than 6 meters. In contrast, inferior film may appear hazy and provide poor visibility.

Texture: Good-quality film has a thick and smooth texture, while inferior film is thin, brittle, and prone to wrinkling.

2. Color Durability: In high-quality film, the color pigment is embedded within the film and is durable, resisting discoloration over time. The color should not fade during the application process using a scraper. On the other hand, poor-quality film may have color in the adhesive layer, and when the film backing is removed and scraped with a fingernail, the color may fade. Additionally, during the application process, the color can peel off, especially in areas where the scraper has been used. Such films are prone to losing color over time, with fading becoming more noticeable after a year.

3. Bubbles: When the plastic backing of the film is removed and reapplied on the car window, poor-quality film may develop bubbles, while high-quality film remains bubble-free. For windscreen security transparent film, it evolves from transparent bulletproof membranes and typically offers more than 70% light transmission.

4. Insulation: Assessing the insulation quality of solar film can be challenging to the naked eye and touch. However, a simple test can provide a comparison: place the glass with the film over an iodine-tungsten lamp. If you can touch the glass without feeling significant heat, it indicates that the film is of high quality. Conversely, if the glass becomes hot to the touch immediately, it suggests that there may be an issue with the film, indicating poor quality.
