A cohesive tape or bandage (also called self adhesive) is designed to adhere only to another tape of the same type. Specifically (and in contrast to adhesive tapes and bandages), these tapes do not adhere to skin, hair or other parts of the body. As a result, you can wrap a cohesive tape or bandage around a limb for support without having to worry about experiencing pain and/or hair loss when you remove it.
A cohesive tape or bandage will have three key variables in its construction – the base material, an elastic yarn and a cohesive technology. The base material used can be fabric or non woven. The elastic yarn can be either linear or knitted.
The quality of elastic yarn will affect the consistency of compression that the bandage provides. Another key determinant of performance is the quality of cohesive used. The better this technology, the more able the self adhesive tape or bandage will be to remain in place for an extended period.
