What are the types of commonly used car wraps?

According to the classification method of glass films by the International Glass Film Association (IWFA), automobile glass films can be divided into three basic types:
​
1. Dyeing film (non-reflective, refers to the reflection of infrared rays). This type of film does not contain a metal layer and has no function of reflecting infrared rays. It has glare control and certain heat insulation functions. It mainly plays the role of heat insulation by absorbing solar energy and then releasing it outwards. The thermal insulation efficiency is much lower than that of reflective film.
​
2. The composite film of dyeing film and vacuum metallization film (reflection) is called high-performance film in the industry. This high-performance film is usually composed of a layer of bulk dyeing film and a layer of vacuum aluminized film. Compared with non-reflective dyed films, it has a higher visible light transmittance and a higher heat insulation rate. However, the dyed layer will scatter light, causing visual distortion, so the clarity is lower. Difference.
​
3. Magnetron sputtering metal film (reflection), also known as pure metal film. This is a film with the highest level of glass film manufacturing technology. This film uses a magnetron sputtering process to coat the film substrate with a layer of different metal ion coatings with extremely high infrared reflectivity. The metals used are usually copper, stainless steel, nickel-chromium alloy, etc. The color of the film is entirely determined by the metal plated.
