  • Patent number: 4499130
    Abstract: A protective, easily removable laminate for application to the carpeting, and decorative seat and wall covering material of vehicles includes a plastic film coated on one surface with an acrylic resin based pressure sensitive adhesive. The film, in one form of the invention, is comprised of unoriented polypropylene capable of stretching and withstanding deep drawing and resisting the heat involved in thermoforming. The pressure sensitive adhesive is essentially of the type which does not adversely affect paint or trim material and which has preferential adhesion failure to the carpeting or seat or wall covering rather than to the film. In another form of the invention, the film, where it is not to be subjected to thermoforming operations, may be of a different composition such as polyethylene terephthalate, oriented polypropylene, polyethylene, or polyvinyl chloride. The method of employing the film in all forms of the invention is to apply the pressure sensitive adhesive to one surface of the film.
