Is the car film applied on the outside or inside of the glass?

[VanKing]

Generally, the film applied to cars is placed on the inner side of the car glass, except for films used in modifications or color changes. Applying the film on the inside prevents exposure to wind and rain, slowing down the aging process and avoiding significant external interference during use, which could otherwise lead to shorter lifespan, poor adhesion causing peeling or lifting edges. Below are the benefits of car window tinting: 1. Extends lifespan: Blocks medium and long-wave UV rays that can penetrate thick glass. A car with window film can block most UV rays from entering the interior, reducing aging of car interiors and extending their lifespan; 2. Glass shatterproofing: Another benefit is its shatterproof effect. When applied to the inner side of the glass, in case of an accident where the glass shatters, the film can hold the broken pieces together, preventing glass fragments from scattering and injuring passengers; 3. Creates a private space: Some types of films allow clear visibility from inside the car while making it difficult or impossible to see inside from the outside, ensuring the privacy and security of the car owner and the interior.
