The reflective thermal film is made from the principle of spherical regression reflection formed by high refractive index glass beads or the principle of cubic angle regression reflection formed by microcrystalline lattice composed of transparent resin. It can reflect light back to its light source and produce excellent reflective effect. Therefore, it can enhance the visibility of moving human body in poor vision or critical situations at night, enhance safety and avoid accidents.

They are widely used, such as the uniforms of police, sanitation workers and firefighters in many countries, as well as in various sportswear, shoes and children's clothing. They have the characteristics of reflective brightness and water washing resistance.

The reflective thermal film is made by using the return reflection principle of glass beads with high refractive index and the advanced technology of focusing post-treatment. It can reflect the distant direct light back to the luminous place, and has good retroreflective optical performance no matter in day or night. Especially at night, it can play the same high visibility as during the day. The safety clothes, short sleeves and other clothes made of this high visibility reflective printing can be easily found by night drivers whether the wearer is in a distant place or under the interference of light or scattered light. The emergence of reflective materials has successfully solved the problem of "seeing" and "being seen" at night.
