1 . A composition comprising the following components: A) an anhydride and/or carboxylic acid functionalized ethylene/alpha-olefin interpolymer comprising the following properties: i) a melt viscosity (177° C.) less than, or equal to, 50,000 cP; and ii) a density from 0.855 to 0.895 g/cc; B) a rosin-based tackifier; and wherein the tackifier is selected from the following: i) a partially hydrogenated glycerol ester; ii) a fully hydrogenated pentaerythritol ester; iii) a fully hydrogenated glycerol ester; iv) a non-hydrogenated ester with a Tg from 30° C. to 50° C.; or v) a combination thereof. 2 . The composition of claim 1 , wherein the tackifier is selected from the following: ii) a fully hydrogenated pentaerythritol ester; iii) a fully hydrogenated glycerol ester; iv) a non-hydrogenated ester with a Tg from 30° C. to 50° C.; or v) a combination thereof. 3 . The composition of claim 1 , wherein the anhydride and/or carboxylic acid functionalized ethylene/alpha-olefin interpolymer of component A has a molecular weight distribution (MWD) from 1.5 to 5.0. 4 . The composition of claim 1 , wherein component A is present in an amount from 30 to 60 weight percent, based on the weight of the composition. 5 . The composition of claim 1 , wherein the weight ratio of component A to component B (A/B) is from 0.50 to 2.00. 6 . The composition of claim 1 , wherein the composition comprises ≧70 wt % of the sum weight of component A and component B, based on the weight of the composition. 7 . The composition of claim 1 , wherein the composition further comprises component C) an ethylene/α-olefin interpolymer. 8 . The composition of claim 7 , wherein the ethylene/α-olefin interpolymer of component C has a density from 0.855 to 0.885 g/cc. 9 . The composition of claim 1 , wherein the composition has a melt viscosity (at 177° C.) from 100 to 2000 mPa·s. 10 . An article comprising at least one component formed from the composition of claim 1 . 11 . The article of claim 10 , further comprising a substrate. 12 . The article of claim 11 , wherein the substrate is selected from the group consisting of the following: a coated substrate, a recycled paper, and combinations thereof. 13 . The article of claim 11 , wherein the substrate is selected from the group consisting of the following: a wax coated Kraft or carton, a polyethylene coated Kraft or carton, a BOPP film laminated Kraft or carton, a polypropylene (PP) film laminated Kraft or carton, a PET film laminated Kraft or carton, a clay coated Kraft or carton, a lacquer coated Kraft or carton, and combinations thereof.
