Traditional engineering grade-reflective film
Dec 06, 2016

Commonly known as "project-class" lens embedded reflective film, is the first class of products of glass beads-reflective film, customary in the industry known as "project-class" series reflective film, invented in 1937.

Engineering grade reflective film in the 1980 of the 20th century in the traditional sense introduced to China in the 1990 of the 20th century, began to appear a number of suppliers within China, this reflective film.

Since in the 1940 of the 20th century, this kind of material has been used successfully to make traffic signs. [5] the advent of the product, for the first time on the road, drivers driving at night can be found in their earlier driving course in front of signs and reflective objects. Due to the advent of this material, in varying degrees, solves the following problem of road traffic safety management challenges:

1. road signs at night long range identification cannot be made;

2. active light consumes resources, some roads are not equipped to provide electric power for the lighting conditions;

3. the active light sources have the potential to interfere with the driver's line of sight, so he saw no shouldn't even look at the contents of;

4. one can meet the low speed and narrow road traffic (General speed before and after in the 1940 of the 20th century) requirement of reflective signs.

Now, in many remote and rural roads, and almost no low-speed roads of light interference environment, this tape is still widely used.
