Convey warnings and create barricades with flagging tape for building and construction, forestry, surveying, traffic control, and warehouse applications. Our regular and biodegradable flagging tapes are made from top-quality materials, including fade-resistant PVC and environmentally-friendly wood pulp, and are suitable for indoor or outdoor use. Find flagging tape in designated colors as required: We offer yellow caution tape, two-color striped warning tape, reflective barrel tape, and detectable underground utility tape. For extra-tough markings, our crack-resistant, fade-resistant Ultra and Tundra Glo flagging tapes can withstand extreme high and low temperatures and humidity. Shop our selection of printed flagging tapes to find options that convey specific messages with graphics and text, or choose perimeter marker flags to block off dangerous or off-limits areas, including options that meet the OSHA-required 500-pound break strength.
