Wrap advertising or a vehicle wrap describe the marketing practice of completely or partially covering (wrapping a vehicle in an advertisement or livery. The result of this process is essentially a mobile billboard. Wrap advertising can be achieved by painting a vehicle’s outer surface, but an increasingly ubiquitous practice in the 21st century involves the use of large vinyl sheets as “decals“. The vinyl sheets can later be removed with relative ease, drastically reducing the costs associated with changing advertisements. While vehicles with large, flat surfaces (such as buses and light-rail carriages) are often used, automobiles can also serve as hosts for wrap advertising, despite consisting of more curved surfaces. Wrap advertising is also used in the magazine and publishing industries.
Decals can be made to cover side and rear windows on a vehicle, but for safety reasons, the front windows used by the driver are not covered. The decals on side windows are typically perforated, so that it is still possible for passengers to look outside. This See-through graphic technology originated in the 1980s, with the first dominant patent registered by a British company called Contra Vision.Wrapped advertisements must often be divided into a number of smaller pieces to appropriately cover any movable panels on the vehicle, such as the fuel tank cover, trunk (boot) openings, and other doors.
