Everyone on the road will often see reflective film, will be curious about what is the principle of reflective? In fact, many of them were made with reflective paint, and now they have begun to use reflective film.

Because reflective film products are a wide range of new optical materials. It is based on the principle of thin lens imaging, the glass beads are evenly embedded in a single layer of organic resin as an optical original, and the film is composed of multiple layers of resin.

And the reflective sign made with it can reflect the incident light according to the original path, and its reflective brightness is tens to hundreds of times brighter than the general paint sign. Products are widely used in road, railway, port, airport, mining, fire, vehicle license, environmental protection, advertising and other fields to make reflective signs, signs. The use of the product can make people see the sign at night at hundreds of meters away, which greatly improves people's ability to identify the sign at night, and achieves the role of enhancing safety awareness and publicity.

Now everywhere can be seen by reflective film made of reflective signs, has been closely related to people's production and life, the application of the product is another progress in science and technology. Reflective film is the use of optical principle, the light can be reversely reflected to the light source of a special structure of the film, composed of weather-resistant skin, glass bead layer, focusing layer, reflection layer, glue layer and the bottom paper layer.
