Abstract
The invention relates to a plaster consisting of a flat element on which an adhesive area (2) is provided. From above, said adhesive area (2) surrounds a non-adhesive area or a pad (5) on the application side. According to the invention, the adhesive area has a first sticking area (3) which surrounds the non-adhesive area or the pad (5) and a second sticking area (4) which is located outside of the first sticking area (3) and surrounds said first sticking area (3). The force of adhesion of the first sticking area (3) (0.5-2 N/25 mm) is less than that of the second sticking area (4) (2-8 N/25 mm). This ensures that the inventive plaster sticks well but can also be removed gently. The invention also relates to a plaster strip and incision plasters.
