Type 5 films are primarily used for delineators and channelizers on highways and streets. It is a unique film in that it is brighter than all other reflective sheeting, thinner, more rugged, made in a single layer, and CAD cuttable. Type 5 is used extensively for non signage applications. Things like DOT tapes, marine applications, trucks, trailers, bollards, trains, dumpsters, shipping containers, buildings, letters, numbers, graphics, and much more. Since it is made in a single layer, it does not delaminate.
Type 5 is primarily manufactured by Orafol and is based on their AP1000 film. To the best of my knowledge, no other manufacturer makes a comparable film. Of note is that the photo-metrics on the spec sheet are the minimum values that the film meets. Actual reflectivity is much higher. A spec sheet on Oralite Type 5 is below –
