Abstract

An absorbent core for use in an absorbent article is provided and comprises a core wrap enclosing an absorbent material, the absorbent material comprising superabsorbent polymer particles. The superabsorbent polymer particles represent less than 85% by weight based on the total weight of the absorbent material. The core wrap comprises a top side and a bottom side, the absorbent core comprises one or more area(s) substantially free of absorbent material through which the top side of the core wrap is attached to the bottom side of the core wrap, so that when the absorbent material swells the core wrap forms one or more channel(s) along the area(s) substantially free of absorbent material. The superabsorbent polymer particles have a value of Absorption Against Pressure (AAP) of at least 22 g/g according to the Absorption Against Pressure Test Method and a bulk density of at least 0.5 g/ml according to the Bulk Density Test Method.
