The main quality discrimination points of the reflective film: the material of the film, the reflection coefficient of the glass beads, the beading rate, the dead bead rate, the average color degree, the weather resistance, the viscosity of the adhesive layer and the like. It is composed of a thin film layer with good weatherability, a layer of tiny glass beads, a focusing layer, a reflective layer, an adhesive layer, and a peeling layer. Using the same kind of ink, various types of patterns can be made using screen printing technology. Generally divided into pressure-sensitive and thermal type two. Reflective film is a special structure of PVC film that uses the optical principle to retroreflect light back to the light source. Generally divided into pressure-sensitive and thermal type two. Using the same kind of ink, various types of patterns can be made using screen printing technology.
