Holographic Rainbow Laser Label Reflective Film Materials is an innovative functional film characterized by high gloss, colorful iridescent effects, and strong reflective properties. Its manufacturing process is a sophisticated integration of precision optical technology and advanced film processing. Commonly used base materials include PET (polyethylene terephthalate) or BOPP (biaxially oriented polypropylene). After the holographic pattern is embossed onto the film surface, a thin, highly reflective aluminum layer is applied through vacuum metallization. Depending on the application, an adhesive layer—such as hot melt adhesive or pressure-sensitive adhesive—is coated onto the back of the aluminum layer, followed by lamination with a release liner. This material that can be directly die-cut into labels, ready for application.
