Is it normal to have small bubbles in the car film?
1 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.
