Description

Foldable reflective film Technical Field The utility model relates to the technical field of reflective films, in particular to a foldable reflective film. Background The reflecting film is a special material for returning light ray according to original path by utilizing optical principle. It can efficiently reflect light from a light source back to an observer's eyes at night or under low light conditions, thereby significantly improving visibility and safety. The characteristic makes the reflective film widely applied to the fields of traffic safety signs, personal protective equipment, advertisement display and the like. Most of the existing reflective films are of integral structures, lack of foldable design, and have the disadvantages of large occupied space due to fixed shape, large occupied space, and increased transportation and storage cost due to large occupied space resources during batch transportation and storage, and the reflective film is easy to wear and damage due to extrusion, collision and the like during transportation, so that the reflective performance and service life of the reflective film are affected. Disclosure of utility model Aiming at the technical problems that most of the reflective films in the prior art are of integral structures and lack of foldable design, because the shape of the reflective films is fixed and the occupied space is large, a large amount of space resources are occupied during batch transportation and storage, the transportation and storage cost is increased, the surface of the reflective films is easily worn and damaged due to extrusion, collision and the like in the transportation process, and the reflective performance and the service life of the reflective films are influenced.
