Polyester Film

• All types of window tinting for cars possess one thing in common. They all contain polyester film. This film goes between the window glass and the rest of the film. As its name suggests, it is made of polyester and is between 2 and 7 mils thick. Polyester film makers coat one side of the film with an adhesive that is either pressure sensitive or water activated in order to hold the film in place.
  
  

Dyed Film

• This type of window tint for cars absorbs heat from the outside. It contains a film that is made of a dye. The dye absorbs the heat by rejecting the heat into the glass. The trapped heat dissipates into the outside air by the movement of the air outside of the car.
  
  

Deposited Film

• This type of window tint for cars helps to hide the interior of the car. It contains a film that possesses a dark and very mirrored exterior. Often seen on limousines and security vehicles, deposited film reflects the images outside of the vehicle but allows those within the vehicle to see outside.
  
  

Sputtered Film

• This type of window tint for cars helps to hide the interior of the car in a similar manner as the deposited film tint but with one important difference. This type of tint contains a film that possesses a mirrored exterior but is much lighter than the deposited film. Thus, while people outside the car will see their images reflected, those inside the vehicle might find it easier to see objects outside because they are not so dark as with the deposited film, although they will not enjoy the benefit of a sunglass.
  
  

Hybrid Film

• This type of window tint for cars combines the qualities of the other types of tints. Hybrid film contains a film that possesses dye and metals. This combination makes the tint both reflective and light.
