1. A method of making a wallboard tape, wherein the wallboard tape comprises a paper substrate having a pH of from about 7.0 to about 10.0 and an internal bond of from about 25 to about 350 milli ft-lb/sq. in. as measured by TAPPI method 541.1 and comprising a plurality of cellulose fibers, a wet st
1. A method of making a wallboard tape, wherein the wallboard tape comprises a paper substrate having a pH of from about 7.0 to about 10.0 and an internal bond of from about 25 to about 350 milli ft-lb/sq. in. as measured by TAPPI method 541.1 and comprising a plurality of cellulose fibers, a wet strength additive, and an alkaline sizing agent, the method comprising the step of; contacting the cellulose fibers consecutively and/or simultaneously with the wet strength additive in an amount of from 0.25 to 2.5 wt % based on the total weight of the paper substrate, and the alkaline sizing agent in an amount of from 0.05 to 1.5 wt % based on the total weight of the paper substrate. 2. The method according to claim 1, wherein the paper substrate has a basis weight of from 50 to 120 lbs/3000 sq. ft. 3. The method according to claim 1 wherein the paper substrate has an apparent density of from 5.0 to 20 lb/3000 sq. ft. per 0.001 inch thickness. 4. The method according to claim 1, wherein the paper substrate has a MD Tensile of from 25 to 100 lbf/inch width. 5. The method according to claim 1, wherein the paper substrate has a CD Tensile of from 5 to 50 lbf/inch width. 6. The method according to claim 1, wherein at least a majority of the plurality of cellulose fibers are softwood fibers. 7. The method according to claim 1, wherein the paper substrate further comprises calcium carbonate. 8. The method according to claim 1, wherein the alkaline sizing agent is at least one member selected from the group consisting of alkyl ketene dimer, alkenyl ketene dimer and alkenyl succinic anhydride. 9. The method according to claim 1, wherein the paper substrate further comprises at least one member selected from the group consisting of a binder, filler, thickener, and preservative. 10. The method according to claim 1, wherein the paper substrate has a width off a winder of a paper machine of from 15 to 100 inches. 11. The method according to claim 1, wherein the wet strength agent is at least one member or combinations selected from the group consisting of a polymeric amine epichlorohydrin, urea formaldehyde, melamine formaldehyde and glyoxylated polyacrylamide resins. 12. The method according to claim 1, wherein the paper substrate further comprises calcium carbonate in at least one form selected from the group consisting of precipitated calcium carbonate and ground calcium carbonate. 13. The method according to claim 1, wherein the alkaline sizing agent is at least one unsaturated hydrocarbon having from 16 to 20 carbon atoms. 14. The method according to claim 1, wherein the paper substrate further comprises a binder. 15. The method according to claim 1, wherein said contacting step occurs within an aqueous environment having a pH of from 7.0 to 10.0. 16. The method according to claim 1, wherein the paper substrate of step (a) has an internal bond of from about 50 to about 250 milli ft-lb/sq. in. as measured by TAPPI method 541. 17. The method according to claim 1, further comprising slitting said paper substrate. 18. The method of according to claim 1, wherein the contacting of the cellulose fibers with the wet strength additive and the alkaline sizing agent is carried out simultaneously. 19. The method of according to claim 1, wherein the contacting of the cellulose fibers with the wet strength additive and the alkaline sizing agent is carried out consecutively. 20. The method according to claim 1, wherein the contacting occurs at the thick stock, thin stock, head box, size press, water box, coater, or a combination thereof. 21. The method according to claim 1, wherein the contacting occurs at the thin stock, thick stock, head box, size press, or a combination thereof. 22. The method according to claim 1, further comprising abrading at least one surface of the paper substrate. 23. The method according to claim 1, further comprising sanding at least one surface of the paper substrate. 24. The method according to claim 1, further comprising slitting said paper substrate. 25. A method of making a wallboard tape, comprising the steps of: (a) preparing a paper substrate having a pH of from about 7.0 to about 10.0 and an internal bond of from about 25 to about 350 milli ft-lb/sq. in. as measured by TAPPI method 541 by contacting a plurality of cellulose fibers consecutively and/or simultaneously with a wet strength additive in an amount of from 0.25 to 2.5 wt % based on the total weight of the paper substrate, and an alkaline sizing agent in an amount of from 0.05 to 1.5 wt % based on the total weight of the paper substrate; and(b) converting the Paper substrate of step (a) to wallboard tape. 26. The method according to claim 25, wherein the alkaline sizing agent is at least one member selected from the group consisting of alkyl ketene dimer, alkenyl ketene dimer and alkenyl succinic anhydride. 27. The method according to claim 25, wherein the wet strength agent is at least one member or combinations selected from the group consisting of a polymeric amine epichlorohydrin, urea formaldehyde, melamine formaldehyde and glyoxylated polyacrylamide resins. 28. The method of according to claim 25, wherein the contacting of the cellulose fibers with the wet strength additive and the alkaline sizing agent is carried out simultaneously. 29. The method of according to claim 25, wherein the contacting of the cellulose fibers with the wet strength additive and the alkaline sizing agent is carried out consecutively. 30. The method according to claim 25, wherein the contacting occurs at the thick stock, thin stock, head box, size press, water box, coater, or any combination thereof. 31. The method according to claim 25, wherein the contacting occurs at the thin stock, thick stock, head box, size press, or any combination thereof. 32.
