A squeezed of absorbent gauze or any other relevant material, attached to a thin flexible strip or fabric, covered with a layer of a pressurized and delicate adhesive material. The squeezed material may comprise of a relevant antimicrobial initiator. The adhesive face is secured by a relevant easily separable layer. The adhesive film of adhesive bandage may be perforated and the other side may be covered with a water-repellent strip.

Material: The adhesive film is normally a woven fabric, plastic like PVC or polyethylene. The adhesive strip is normally an acrylate, for example epoxy diacrylates and methacrylates. These are also referred as vinyl resins.
The absorbent pad is usually produced from cotton, and there is at time a scant, spacious-polymer covering over the pad, to avoid it from sticking to the wound. The pad is also medically treated with an antiseptic agent. In some strips, the pad is formed of a water-soaking gel. This is particularly normal in dressings utilized on blisters, as the gel behaves and acts as a cushion.
Caution: Many folks have allergies to many of these materials, specially latex and few other adhesives. Therefore FDA recommends latex free materials to be used for this purpose.
