Adhesive article with a barrier layer

A method of making an adhesive article comprising:

• embedding a barrier layer between a a first and a second heat-bondable polymeric layers by coextrusion, wherein the barrier layer has opposed first and second major surfaces and is substantially impermeable to oxygen gas at ambient temperature and pressure;
• and wherein the first heat-bondable polymeric layer extends across and is coupled to the first major surface of the barrier layer;
• coupling one of the heat-bondable layers to a first major surface of a polymeric foam backing;
• wherein the polymeric foam backing extends across and is coupled to the second major surface of the barrier layer and
• coupling a pressure sensitive adhesive layer extends across and is coupled to the second major surface of the backing opposite the first major surface.
