Abstract
An elastic and resilient film for application to an endless moving handrail includes a first layer having a top surface and a bottom surface and having sufficient resilience to accommodate strains occurring on the surface of the endless moving handrail, the first layer having an adhesive on the bottom surface and a first barrier coating on the top surface, the first barrier coating having sufficient resilience to accommodate strains occurring on the surface of the endless moving handrail and substantially retarding the transmission of materials blooming from the endless moving handrail, optionally a second layer having a top surface and a bottom surface overlying the first layer, the second layer having sufficient resilience to accommodate strains occurring on the surface of the endless moving handrail, and further having second adhesive on the bottom surface of the second layer, and a substantially transparent layer overlying the top surface of the second layer, or the first layer if no second layer present.
