HOT MEL ADHESIVE COMPOSITION INCLUDING A CRYSTALLINE BLOCK COMPOSITION. A hot melt adhesive composition includes (A) 20-95% by weight of a polymer component including an ethylene-based polymer and a propylene-based polymer, the ethylene-based polymer present in an amount greater than 30 % by weight, based on a total weight of the polymer component, and (B) 1-60% by weight of a crystalline block composite comprising (1) a crystalline ethylene-based polymer, (2) a polymer at crystalline alpha-olefin base derived from at least one of a C3-10 olefin, and (3) a block copolymer comprising 10-90% by weight of a crystalline ethylene block comprising 90% or more by weight of units derived from ethylene and comprising 10-90% by weight of a crystalline alpha-olefin block comprising 90% or more by weight of units derived from at least one of a C3-10 alpha-olefin, (C) optionally, from greater than zero to 70% by weight of tackifier, and (D) optionally, from greater than zero to 40% by weight of at least one selected from the group of a wax and an oil. |
