function of 3M reflective film

Safety protection products made of reflective materials can produce strong reflection under a certain light source, providing the most effective and reliable safety for pedestrians or night workers in the dark.

The 3M reflective film is a special structure of PVC film that uses optical principles to retroreflect light back to the source. It consists of a film layer with good weather resistance, a micro glass bead layer, a focusing layer, a reflective layer, an adhesive layer and a release layer.
