1. A disposable absorbent article which comprises a chassis having a front waist region, a back waist region, and a crotch region between the front and back waist regions, said chassis having two opposing longitudinal edges and two perpendicularly placed end edges, said chassis further comprising: a. a liquid permeable topsheet spanning at least the crotch region;b. a backsheet spanning at least the crotch region;c. an absorbent core disposed between said topsheet and backsheet; andd. an elastic member disposed along at least one opposing longitudinal edge in either the front waist or back waist region of said chassis wherein said member comprises a non-breathable, unapertured, skinless elastomeric layer selected from the group consisting of styrene isoprene styrene block copolymers, styrene butadiene styrene block copolymers, styrene ethylene butylene styrene block copolymers, and combinations thereof, wherein said elastic member takes the form of three or more strips placed in parallel, non-parallel or a combination of parallel and non-parallel positions to one another on or between one or more additional nonwoven webs,wherein the elastomeric layer is subjected to an anti-blocking treatment comprising treatment with a powder additive prior to lamination with said one or more additional nonwoven webs that prevents the elastomeric layer from sticking to itself prior to such lamination with said one or more additional nonwoven webs,wherein said treatment of the elastomeric layer with a powder additive comprises application of the powder to one or both surfaces of the elastomeric layer, andwherein said elastomeric layer exhibits an Energy Recovery Value of at least about 0.77. 2. The article according to claim 1 wherein said elastic member is included in a disposable article component that is selected from a group consisting of elastic side panels, leg cuffs, waistbands, outer covers, landing zones, and combinations thereof. 3. The article according to claim 1 wherein said elastic member is included in an elastic side panel that is disposed along at least one longitudinal edge of said chassis. 4. The article according to claim 1 wherein said layer exhibits an Energy Recovery Value of at least about 0.79. 5. The article according to claim 1 wherein said layer exhibits an Energy Recovery value of at least about 0.83. 6. The article according to claim 1 wherein the powder is selected from the group consisting of talc, mica, mullite, calcium carbonate, silica, powdered polyethylene, corn starch, barium sulfate, gypsum, activated carbon, polyolefin, alginate, aluminum silicate, bentonite, carbon black, carbon nanotubes, chalk, cobalt acetate, dicalite perlite, dolomite calfix, flour, graphite, hydroxy ethyl cellulose, kaolin, polyethylene wax, polyvinyl alcohol, rice flour, starch, modified starch, super absorbent, vermiculite, wax powder, oxides of bismuth, cerium, zirconium, manganese, magnesium, iron, zinc, aluminum, calcium, silicon, strontium and titanium, and combinations thereof. 7. The article according to claim 6 wherein the powder is selected from the group consisting of calcium carbonate, talc, corn starch, and combinations thereof. 8. The article according to claim 3 wherein the elastic side panel is disposed along at least one longitudinal edge of said chassis in said back waist region. 9. The article according to claim 3 wherein the elastic side panel is disposed along at least one longitudinal edge of said chassis in said front waist region. 10. A disposable absorbent article which comprises a chassis having a front waist region, a back waist region, and a crotch region between the front and back waist regions, said chassis having two opposing longitudinal edges and two perpendicularly placed end edges, said chassis further comprising: a. a liquid permeable topsheet spanning at least the crotch region;b. a backsheet spanning at least the crotch region;c. an absorbent core disposed between said topsheet and backsheet;d. an elastic member that is an elastic side panel disposed along at least one opposing longitudinal edge in either the front waist or back waist region of said chassis wherein said member comprises a non-breathable, unapertured, skinless elastomeric layer selected from the group consisting of styrene isoprene styrene block copolymers, styrene butadiene styrene block copolymers, styrene ethylene butylene styrene block copolymers, and combinations thereof, wherein said elastic member takes the form of three or more strips placed in parallel, non-parallel or a combination of parallel and non-parallel positions to one another on or between one or more additional nonwoven webs,wherein the elastomeric layer is subjected to an anti-blocking treatment comprising treatment with a powder additive prior to lamination with said one or more additional nonwoven webs that prevents the elastomeric layer from sticking to itself prior to such lamination with said one or more additional nonwoven webs,wherein said treatment of the elastomeric layer with a powder additive comprises application of the powder to one or both surfaces of the elastomeric layer, andwherein said elastomeric layer exhibits an Energy Recovery Value of at least about 0.77; ande. a fastener attached to an outermost edge of said side panel. 11. The article of claim 10 wherein said fastener is selected from the group consisting of tape tabs, hook and loop fastening components, interlocking fasteners, and combinations thereof, wherein the interlocking fasteners are selected from the group consisting of tabs & slots, buckles, buttons, snaps, and/or hermaphroditic fastening components. 12. The article according to claim 7 wherein the powder is corn starch. 13. The article according to claim 10 wherein the powder is selected from the group consisting of talc, mica, mullite, calcium carbonate, silica, powdered polyethylene, corn starch, barium sulfate, gypsum, activated carbon, polyolefin, alginate, aluminum silicate, bentonite, carbon black, carbon nanotubes, chalk, cobalt acetate, dicalite perlite, dolomite calfix, flour, graphite, hydroxy ethyl cellulose, kaolin, polyethylene wax, polyvinyl alcohol, rice flour, starch, modified starch, super absorbent, vermiculite, wax powder, oxides of bismuth, cerium, zirconium, manganese, magnesium, iron, zinc, aluminum, calcium, silicon, strontium and titanium, and combinations thereof. 14. The article according to claim 13 wherein the powder is selected from the group consisting of calcium carbonate, talc, corn starch, and combinations thereof. 15. The article according to claim 14 wherein the powder is corn starch.
