Reflective film is a kind of retro-reflective raw material that has been made into plastic film and can be directly used. The technology of reflective materials is developing rapidly. The technology of my country's reflective material industry is gradually improving and innovating, which plays a positive role in promoting the technological development of the entire domestic reflective material industry.

Prismatic reflective film is based on the principle of thin lens imaging. Glass beads are evenly embedded in organic resin on one side as an optical original, and then laminated with epoxy resin to form a glass film.

The base film of highway traffic signs generally uses super-strong reflective film. Compared with diamond-grade reflective film, super-strong reflective film is more affordable. At the same time, the service life of super-strong reflective film can also meet the use requirements of high-speed reflective film.

Prismatic reflective film is made by hot pressing, which first uses microprisms and substrates to press into reflective film, and then coats it with a layer of metal aluminum. However, when the hot pressed pyramids are affected by external factors such as extrusion, weather changes, and water washing, they are easily damaged and deformed, resulting in a significant decrease in reflective function, so this article introduces a new technology attempt.

The choice of traffic sign reflective film should be based on the surface scratches, whether the edge is deformed, whether the color is consistent, etc. In the process of film pasting, cleaning and washing products need to be paid attention to, or choose an excellent position to see whether the film is pasted correctly.

Prismatic reflective film is different from micro-bead reflective film. It is mainly used in signs and signs of some urban expressways, urban trunk roads, highways and other high-grade roads. Due to the needs of infrastructure construction, this product is widely demanded.
