What kind of material is made of reflective film? Who knows?
The grade of reflective film is divided into diamond grade, high strength grade, engineering grade and economic grade.Reflective film is mainly used in all kinds of road and rail guide signs, signs, mines, airports, security cards, stage scenery, trademarks, land brands, plates and so on.
Reflective film is a kind of PVC film with special structure which can reverse light back to light source by optical principle. The film is composed of a film layer with good weather resistance, a micro glass bead layer, a focusing layer, a reflecting layer, a viscose layer and a peeling layer.The main point to identify the quality of reflective film: film material, the Pearl rate reflecting coefficient of glass beads, beads, death rate, color uniformity, weatherability, adhesive viscosity etc..
The safety protective articles made of reflective materials can produce strong light reflection effect under the irradiation of a certain light source, and provide the most effective and reliable safety guarantee for pedestrians or night operations personnel in the dark.
