For an environmentally-friendly tape option, use Biodegradable Caution Tape. This Presco brand barricade tape comes in the color red with the pre-printed text "DANGER DO NOT ENTER". It is made of a non-woven, cellulosic material developed from wood pulp. And in addition to being biodegradable, this tape is 100% non-toxic to humans, animals, and the environment. Each roll is 150 feet in length and is sold individually. Presco biodegradable caution tape will break down and eventually disintegrate, eliminating plastic trash and waste.
