Will small bubbles in car film disappear on their own?
4 Answers
Small bubbles in car film will not disappear on their own and need to be manually removed by puncturing the bubbles. The bubbles in car film are caused by air trapped between the film and the glass. These bubbles are completely sealed between the window and the film with no way to escape, so they will persist and cannot disappear in a short time. Car film refers to a thin layer of material applied to the front and rear windshields, side windows, and sunroof of a vehicle. This material is also known as solar film or heat-insulating film. Its main functions include blocking ultraviolet rays, reducing heat, preventing injuries from glass shattering, reducing glare, and protecting personal privacy due to the one-way visibility feature of the film.
I've worked in the automotive decoration industry for a long time and often see small bubbles after film installation. Those tiny bubbles, if caused by trapped air during installation, usually shrink or disappear on their own within a few days to a week, as the film material has shrinking properties, especially noticeable in hot weather. However, it's important to note that bubbles containing moisture or larger ones are unlikely to disappear automatically and may leave permanent marks or wrinkles. It's recommended not to wash the car or touch the film immediately after installation; instead, wait patiently for a few days to observe changes. If the bubbles don't disappear, seek professional help to remove them with proper tools rather than scraping them yourself to avoid damaging the film surface. Choosing a reputable shop for installation is key to preventing bubble formation.
As an ordinary car owner, I once made a mistake while applying film myself and ended up with small bubbles. After talking to a mechanic friend, he mentioned that many small bubbles disappear naturally as the film expands and contracts with heat, conforming to the glass. I tried waiting for a week, and after parking in the sun a few times, some bubbles indeed vanished, but the larger ones at the edges remained unchanged. Unaddressed bubbles can affect visibility and aesthetics, so I recommend keeping the car ventilated and dry after applying new film, avoiding opening windows or exposing it to direct sunlight to prevent exacerbating the issue. If bubbles persist, returning to the original shop for assistance is more reliable, as DIY attempts can easily go wrong. Applying film is a delicate job, so it's safer to rely on experienced professionals.
Most car film materials are PVC-based and elastic. Small bubbles are residual air or moisture after installation, which may dissipate as the film shrinks, especially in high-temperature environments within a few days. However, large bubbles or those containing moisture are less likely to disappear because water evaporates slowly. Do not interfere after application; wait a week to observe changes. If they persist, professional treatment is needed to prevent long-term damage to the film. Choosing UV-resistant film can ensure better adhesion.
