Abstract: The present invention is related to adhesives comprising 75 to 95 wt % of a polymer blend and a tackifier. The polymer blend has a first propylene-based polymer that is a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin; and a second propylene-based polymer, different than the first propylene-based polymer, that is a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin. The blend has a melt temperature of 75 to 125° C.
