The dressing includes a tissue interface and a sealing member. The dressing further includes a sealing tape configured to be coupled to the sealing member and epidermis. The sealing tape includes a bonding adhesive and a sealing adhesive coupled to a side of the sealing tape. The sealing tape includes a layer of the bonding adhesive disposed on a film layer and a layer of sealing adhesive having one or more apertures disposed on the bonding adhesive. The sealing tape can include a layer of the bonding adhesive disposed on a portion of a film layer and a layer of the sealing adhesive disposed on a uncovered portions of the film layer. ## Claims ### Claim 1 A dressing for treating a tissue site with negative pressure, the dressing comprising: a tissue interface configured to be positioned adjacent to the tissue site; a sealing member configured to be positioned over the tissue interface and the tissue site to form a sealed environment; and a sealing tape comprising: a bonding adhesive layer comprising a bonding adhesive disposed in a continuous layer and having a high-bond strength; and a sealing adhesive layer comprising a sealing adhesive disposed in a continuous layer and having a low-bond strength, the sealing adhesive layer having portions removed to expose the bonding adhesive layer through the sealing adhesive layer, the sealing tape being elongated and configured to attach the sealing member to epidermis, wherein the bonding adhesive layer and the sealing adhesive layer are coincident. ### Claim 2 (depends on 1) The dressing of claim 1, wherein the sealing tape is configured to be coupled over edges of the sealing member so that the sealing tape is partially coupled to the epidermis and partially coupled to the sealing member. ### Claim 3 (depends on 1) The dressing of claim 1, wherein the sealing tape is configured to be coupled to the epidermis adjacent to the tissue site and the sealing member is coupled to the sealing tape so that the sealing tape is between the sealing member and the epidermis. ### Claim 4 (depends on 1) The dressing of claim 1, wherein the sealing tape further comprises: a film layer coupled to the bonding adhesive; and the sealing adhesive layer is coupled to the bonding adhesive layer, the portions removed forming a first pattern and exposing the bonding adhesive layer in a second pattern. ### Claim 5 (depends on 4) The dressing of claim 4, wherein the first pattern comprises a layer having at least one row of apertures disposed proximate a center of the sealing tape and the second pattern comprises remaining portions of the sealing tape. ### Claim 6 (depends on 4) The dressing of claim 4, wherein the first pattern comprises a layer having at least two rows of apertures and the second pattern comprises remaining portions of the sealing tape. ### Claim 7 (depends on 6) The dressing of claim 6, wherein the rows of apertures are offset from each other. ### Claim 8 (depends on 4) The dressing of claim 4, wherein: the first pattern comprises a layer having a first plurality of apertures disposed in a pattern on the sealing tape and a second plurality of apertures having shapes that are a portion of shapes of the first plurality of apertures, the second plurality of apertures disposed adjacent to an edge of the sealing tape; and the second pattern comprises the remaining portions of the sealing tape. ### Claim 9 (depends on 8) The dressing of claim 8, wherein the first plurality of apertures have a circular shape and the second plurality of apertures have a semi-circular shape. ### Claim 10 (depends on 4) The dressing of claim 4, wherein the first pattern comprises a plurality of apertures positioned adjacent to edges of the sealing tape and the second pattern comprises the remaining portions of the sealing tape. ### Claim 11 (depends on 1) The dressing of claim 1, wherein the sealing tape further comprises an expanding agent mixed with at least one of the bonding adhesive and the sealing adhesive. ### Claim 12 A system for treating a tissue site with negative-pressure, the system comprising: a manifold configured to be positioned adjacent to the tissue site; a drape configured to be positioned over the tissue site and the manifold and seal to tissue adjacent to the tissue site to form a sealed space; a negative-pressure source configured to provide negative-pressure to the sealed space; and a sealing tape configured to be coupled to the drape and epidermis, the sealing tape being elongated and comprising; a bonding adhesive layer coupled to a side of the sealing tape, the bonding adhesive layer comprising a bonding adhesive disposed in a continuous layer and having a high-bond strength; and a sealing adhesive layer comprising a sealing adhesive disposed in a continuous layer and having a low-bond strength, the sealing adhesive layer coupled to the bonding adhesive layer and having portions removed to expose the bonding adhesive layer through the sealing adhesive layer, wherein the bonding adhesive layer and the sealing adhesive layer are coincident. ### Claim 13 (depends on 12) The system of claim 12, wherein the sealing tape is configured to be coupled over edges of the drape so that each sealing tape is partially coupled to the epidermis and partially coupled to the drape. ### Claim 14 (depends on 12) The system of claim 12, wherein the sealing tape is configured to be coupled to the epidermis and the drape is coupled to the sealing tape so that the sealing tape is between the drape and the epidermis. ### Claim 15 (depends on 12) The system of claim 12, wherein the sealing tape further comprises: a film layer coupled to the bonding adhesive layer; and the portions removed to forming a first pattern and exposing the bonding adhesive layer in a second pattern. ### Claim 16 (depends on 15) The system of claim 15, wherein the first pattern comprises a layer having at least one row of apertures disposed proximate a center of the sealing tape and the second pattern comprises remaining portions of the sealing tape. ### Claim 17 (depends on 15) The system of claim 15, wherein the first pattern comprises a layer having at least two rows of apertures and the second pattern comprises remaining portions of the sealing tape. ### Claim 18 (depends on 17) The system of claim 17, wherein the rows of apertures are offset from each other. ### Claim 19 (depends on 15) The system of claim 15, wherein: the first pattern comprises a layer having a first plurality of apertures disposed in a pattern on the sealing tape and a second plurality of apertures having shapes that are a portion of shapes of the first plurality of apertures, the second plurality of apertures disposed adjacent to an edge of the sealing tape; and the second pattern comprises the remaining portions of the sealing tape. ### Claim 20 (depends on 19) The system of claim 19, wherein first plurality of apertures have a circular shape and the second plurality of apertures have a semi-circular shape. ### Claim 21 (depends on 15) The system of claim 15, wherein the first pattern comprises a layer having a plurality of apertures positioned adjacent to edges of the sealing tape and the second pattern comprises the remaining portions of the sealing tape. ### Claim 22 (depends on 12) The system of claim 12, wherein the sealing tape further comprises an expanding agent mixed with at least one of the bonding adhesive and the sealing adhesive.
