How is Vinyl Wrap Made?
Vinyl wrap films are made for a few basic raw materials the primary of which is polyvinylchloride (PVC) polymer. PVS polymer is a plastic that has a relatively rigid property. When making vinyl wrap, PVC is combined with a plasticizer to make the film flexible, pigment to create the desired color of the vinyl, heat stabilizers, fillers, processing aids, and special additives which help the vinyl to achieve its UV absorber characteristics to improve UV radiation resistance. The raw materials used in this process change range in their level of quality which will result in the vinyl wraps durability rating.
Beyond just the raw materials used to manufacture vinyl wrap, the manufacturing process, as well as the type of plasticizer that is used to create the vinyl wrap, has the biggest impact on the vinyl’s durability. There are two different processes that are used to manufacture vinyl wrap, casting and calendaring. Each of these processes results in a vastly different quality of vinyl film. In general, the casting process is the preferred method of manufacturing which results in higher quality films. The plasticizers grade used in the casting process is what determines the vinyl wraps flexibility. For pressure-sensitive adhesive films, monomeric or polymeric plasticizers can be used. Polymeric plasticizer is considered the higher grade material where monomeric is the lower grade which is also cheaper.
