Plasters are a kind of adhesive bandage made from bleached cotton fabrics. An adhesive compound is spread on one side of the bandage to make it stick to the skin. Plasters may be either medicated or unmedicated. Some common plasters include the following:
Rubber Adhesive Plaster:
This is a bleached cotton fabric of prescribed standard, prepared with an adhesive compound spread on one side and waterproofed with rubber on the other side.
Zinc Oxide Plaster:
This is similar to Rubber adhesive plaster, but medicated with 20 to 30 percent of zinc oxide added to the adhesive compound.
Elastic Adhesive Plaster:
This consists of medicated elastic cotton fabric, spread with an adhesive compound, which contains 20 to 30 percent of Zinc oxide.
Plaster of Paris Bandage:
