Type 7 – Highway Traffic Signs, Construction Zone Devices, and Traffic Delineators (Discontinued – replaced by Type 8 & 11 sheeting for signs and Type 5 sheeting for zone devices and delineators)
Type 7 Reflective Sheeting – An ultra high intensity prismatic retro-reflective sheeting having the best retro-reflectivity characteristics at LONG and medium road distances. (brightest highway sign film, along with Type 8) as per the reflectivity values of Table 1 at 0.1° and 0.2° observation angles) This sheeting is normally an air backed unmetallized micro-prismatic material. Common applications for this sheeting are (or were) permanent traffic/highway signage, construction zone devices, and traffic delineators. Type 8, Type 11 and Type 5 films now fill these applications. Type 5 is thinner, more rugged, and brighter.
