Is it normal to have small bubbles in the car film?

[AlexRose]

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.

I also had some small bubbles in the film I applied a while ago. After chatting with friends, I found out that everyone has encountered this issue. It's said that bubbles are normal in the first few days after application, caused by trapped air, and they will gradually disappear as the moisture evaporates. I resisted the urge to touch them, and sure enough, they were gone after a few days. However, if you notice the bubbles aren't changing, try gently scraping the surface with a bank card—don't press too hard, or you might damage the film. After applying the film, try to avoid high-temperature environments and park in shaded areas to prevent the bubbles from worsening.

I'm used to applying films myself and often encounter bubble issues. It's usually caused by uneven scraping during installation or trapped air inside, which is normal. After application, use a hairdryer on low heat to blow at the bubbles for a few seconds, then carefully squeeze them out with a soft cloth-wrapped scraper. This method can basically solve the problem. High-quality films with good material and strong ductility have lower bubble risks. Thoroughly cleaning the car windows before application is also crucial, as excessive dust can trap air and cause persistent bubbles.

Small bubbles after film installation are generally not a big issue in the short term, as most will disappear within a few days. However, if left unaddressed for a long time, these bubbles can affect the overall adhesion of the film, potentially causing edges to lift or reducing heat insulation effectiveness. Choosing a reputable shop and high-quality film during installation can minimize the chances of bubble formation. Monitor the bubbles closely within the first week after installation. If they persist stubbornly, it's advisable to have a technician assess the situation to avoid complicating repairs by delaying action.

Don't panic if you notice small bubbles in your car film—it's normal right after installation. High-quality films with good heat resistance will see bubbles disappear faster. Ensuring the glass is clean and properly installed during the process can minimize bubbles. If bubbles appear, gently use a professional squeegee to press out the air while smoothing the film surface to avoid damage. Remember, avoid strong water pressure or intense light in the first few days after installation to prevent worsening the issue.
