The dressing comprises of three layers, each of which plays an important role
This skin contact layer is non-adherent. The polyethylene film helps prevent tissue adhering to the dressing – thereby aiding removal when changing the dressing. This layer also helps keep the skin dry.
This is the absorbent layer. The middle section is constructed of viscose to ensure maximum absorbency, through capillary action which draws mucus away from the skin.
This viscose / polyethylene combination provides an effective seal which retains mucus within the body of the dressing.
