Photoluminescent warning tapes are primarily applied to mark dangerous protrusions and obstacles. The black diagonal contrast color stripes are protected by a clear surface lamination. This important product feature ensures that the stripes cannot accidentally be removed or wiped off with solvents or other cleaning agents during routine cleaning. Competitive products typically only have the colored stripes printed onto the vinyl surface without surface protection. Photoluminescent stripes appear pale yellow in light and glow in darkness. Warning tape is not suitable for floor use. If you require floor markings, please contact Hawk Labeling Systems at 1-800-458-3430 or email labelman@hawklabeling.com.
