An absorbent core for an absorbent article, the absorbent core comprising: a first absorbent layer comprising a first substrate, a layer of first superabsorbent polymer particles deposited on the first substrate on a deposition area, and a fibrous layer of thermoplastic adhesive material covering the layer of first superabsorbent polymer particles, wherein the layer of first superabsorbent polymer particles is substantially cellulose free; and a second absorbent layer comprising a second substrate and a mixed layer comprising a mixture of second superabsorbent polymer particles and cellulosic fibers deposited on the second substrate; the first absorbent layer and the second absorbent layer being combined together such that at least a portion of the fibrous layer of thermoplastic adhesive material of the first absorbent layer contacts at least a portion of the mixed layer of the second absorbent layer; and wherein the core has a longitudinal axis, and the first absorbent layer comprises one or more channels substantially extending in the longitudinal direction of the core, the channels being free of first superabsorbent particles and each channel being defined by continuous side wall portions; wherein in the channels the first substrate is bonded to the side wall portions; and wherein the first substrate is C-wrapped along longitudinal edges of the core to form C-flaps and the second substrate is placed inwardly of these C-flaps.
