FIELD: medicine.SUBSTANCE: invention refers to medicine. What is described is an adhesion cover having a substrate, and an adhesion cover formed at least on one surface of the substrate, wherein the adhesion cover has a periphery and a centre; the adhesion layer has voids; the voids in the adhesion layer are localised in the periphery; the adhesion layer in the centre substantially has no voids, while the periphery of the adhesion layer preferentially comprises the voids in the average number of 2.0 to 100 voids/mm.EFFECT: adhesion cover is highly resistant to skin separation; there is no easy protrusion of the component of the adhesion layer from an edge of the adhesion cover when stored in a package; inhibited adhesion of the adhesion cover to the inner surface of the package; the adhesion cover can be easily removed from the package and avoided rise of the edges of the adhesion cover caused by cold plastic flow during adhesion to skin.8 cl, 6 dwg, 1 tbl, 4 ex |
