Can adhesive vinyl be applied to plastic? That’s an excellent question, and the answer is…maybe. It depends on the type of plastic, the chemical formula. Some plastics take readily to adhesive vinyl graphics application, others don’t, and still others will work, but only if installed properly.
Can I apply vinyl to plastics?
According to experts, applying adhesive vinyl graphics to plastic can be a challenge. Some are friendly, and some are not. Outgassing is a possibility much of the time. Before considering wrapping a plastic substrate, you need to know its chemical composition.
Polycarbonates are used on equipment for automotive, home, and the office. Polycarbonates contain water which when covered with vinyl graphics may outgas forming water bubbles between the substrate and vinyl. An experienced applicator can determine the best method of installation, dry or wet.
Polymethacrylate (PMMA) is the clear, shatterproof plastic used as a replacement for glass. Most adhesives will stick to a PMMA surface; however wet installation may be the best to avoid outgassing.
Polyethylene is used for plastic bags, containers, bottles, and tarps. Vinyl can be applied to this material using dry application and for some applications heat may be required.
Polystyrene is a hard plastic. For example, computer casings are made from polystyrene. This material can be wrapped, but outgassing varies from formula to formula and may cause separation.
Styrofoam is a polystyrene plastic, and although vinyl can be applied it’s difficult and isn’t recommended on some types of Styrofoam
Polyvinylchloride (PVC) is in most cases user-friendly for adhesive vinyl application; however the hardness of the plastic impacts the installation. Hard PVC will accept the vinyl, but may be difficult to remove while softer PVC may not offer the best adhesive surface.
The answer is Yes and No
Proper adhesion of vinyl graphics on plastics depends on several variables that include the type of plastic and how it was produced. Much of the success or failure will depend on the knowledge and experience of the applicator. Should it be installed wet, dry, or not at all? Other factors such as the condition and cleanliness of the surface as well as temperature and humidity during installation will impact the appearance and longevity of the graphic.
