1. A method of producing a composite, the method comprising extruding a corrosion-inhibiting mixture comprising an elastomer having a melt flow index of about 10 g/10 mins to about 300 g/10 mins and a corrosion inhibitor onto a surface of a first nonwoven at an extrusion temperature of from about 170° C. to about 320° C. to form a film layer on the first nonwoven;
wherein the film layer is vapor-permeable and substantially water-impemable, and wherein the combination of the elastomer and the corrosion inhibitor impart corrosion protection and breathability to the composite.
