Is the rear window film applied on the inside or outside of the car?

[LaSerenity]

Automotive rear window film is applied on the inside. The following is an introduction to automotive glass: 1. Introduction: Automotive glass is manufactured by heating the glass to near softening temperature in a furnace, then rapidly transferring it to air grids with varying cooling intensities for uneven cooling. 2. Function: This process creates different stress zones between the main viewing area and peripheral areas of the glass. Typically, glass produced this way is zone-tempered glass. 3. Application: The peripheral areas are positioned in the strong cooling zones of the air grids, requiring full tempering. These areas exhibit good fragmentation characteristics and high tempering strength. The main viewing area is located in the weak cooling zones, resulting in larger fragments and lower tempering strength.
