Retroreflective sheeting is a retroreflective material that has been made into films for direct use, and is also the most widely used retroreflective material. In 1937, the first retroreflective sheeting in the world was produced in a laboratory in the United states. Is the starting point of the history of the large-scale application of the reflective film of the traffic sign. In 1939, a sign board made of reflective film was used in open air for the first time at the highway side of Minnesota in the United states, and therefore, a new period that a series of reflective products are used for traffic signs is uncovered, and a brand-new traffic safety industry is created.

2. Powerful portion of gluing is the semicircle arcuation, and it includes bottom surface and arc surface, the bottom surface laminate in the lower bottom surface on viscose layer, the bottom surface with the arc surface forms a cavity jointly, the cavity intussuseption is filled with adhesion promoter, and powerful portion of gluing adopts flexible material, can break after the extrusion, and the adhesion promoter of inside cavity intussuseption can release, provides more powerful viscidity with viscose layer synergistic effect each other, guarantees that the reflective membrane body can not drop.

3. The bottom surface and the arc surface are integrally formed, so that the integrity of the bottom surface is ensured, and the technical problems that the sealing property is insufficient and the adhesion promoter permeates out in the cavity due to non-integrity are solved.

4. The lower bottom surface of the adhesive layer is covered with an anti-sticking paper layer, and the anti-sticking paper layer is arranged to facilitate the carrying of the reflective film without being carried in a roll.

5. The diamond drill is in a diamond cone shape and comprises at least five reflecting surfaces, and the refractive indexes of light rays can be better brought by the plurality of refracting surfaces, so that better light reflecting performance is brought.

6. The viscose layer is pressure sensitive adhesive layer or resin glue film, and pressure sensitive adhesive or resin glue are the environment-friendly viscose, can not produce the pollution, and its texture is soft simultaneously, avoids insolateing easy fracture after air-drying.
