History of Reflective Sheeting 

Reflective sheeting is classified by prismatic and enclosed glass beaded type, both can be used for road safety and personal safety.

1939, 3M launched Engineer grade reflective sheeting, as enclosed beaded sheeting, it is popular in the graphics industry for letters, shapes, and designs cut in the material.

1971, 3M introduced high-intensity grade reflective sheeting, it is good for sign backgrounds, since cutting the film opens up the cells and allows water intrude, thus it is not often using for letters or shapes.

Prismatic started in 1963 by the American Rowland brothers, this was done in cooperation with Luce Reflexite and later with Fresnel Optics, these companies were later merged together, was patented in 1970 and called Reflexite and so on
