Abstract
A wound dressing includes an inelastic absorbent layer, an elastic film, and a plurality of welds. The inelastic absorbent layer is configured to absorb wound fluid and has a first side and a second, wound-facing side. The elastic film is configured to elastically stretch when a stretching force is applied to the wound dressing and elastically recover when the stretching force is removed. The plurality of welds fix the elastic film to the first side of the inelastic absorbent layer such that the elastic film and the inelastic absorbent layer elastically stretch and elastically recover as a unit.
