Is it normal to have small bubbles in the car film?
2 Answers
If the bubbles are caused by moisture, it is normal. Here is an introduction to car film: 1. Introduction: Car film is a thin layer applied to the front and rear windshields, side windows, and sunroof of a vehicle. This thin layer is also called a solar film or heat-insulating film. 2. Function: Its main functions are to block ultraviolet rays, reduce heat, prevent injuries caused by flying glass, reduce glare, and protect personal privacy through the one-way transparency of the solar film. 3. Thickness: The thickness of car heat-insulating film is usually around 1.5 mil. Mil is an imperial unit, where 1 mil equals one-thousandth of an inch, or 0.0254 mm.
I just noticed some small bubbles when applying the car film. I asked a professional, and he said it's quite common, mainly due to air not being completely expelled during the application process. The bubbles should disappear on their own within a day or two, so no need to worry too much. If they don't go away, you can gently press the bubbles with a soft squeegee to let the air out, but be careful to avoid scratching the film. It's best not to expose the car to direct sunlight or wash it for the first three to five days after application, as the new film hasn't fully adhered yet. If the bubbles grow larger or persist after a week, it might indicate improper installation, and you may need to have it redone to prevent wrinkles or damage to the film.
