Abstract
A dressing is described having a backing layer, an (absorbent) pad, an adhesive coating and a release liner. The release liner is releasably attached to the adhesive coating. The release liner is configured to stiffen up and protect protrusions and/or border portions of the dressing that may otherwise be wrinkled, folded, kinked or otherwise damaged or impaired prior to (transportation or storage) or during application at the point-of-use. The dressing can be used for wound treatment. The dressing can prevent shearing and/or friction from causing (deep tissue) skin damage.
