A disposable absorbent article comprising: a chassis including a topsheet and a backsheet; and an absorbent core, which is substantially cellulose free, located between the topsheet and the backsheet and having a wearer facing side oriented toward a wearer when the article is being worn and an opposed garment facing side, the absorbent core comprising (i) a storage layer which comprises an absorbent particulate polymer material and has a wearer facing side and an opposed garment facing side, (ii) a first core wrap sheet covering the wearer facing side of the storage layer, the first core wrap sheet being a first substrate for a first absorbent layer, and (iii) a second core wrap sheet covering the garment facing side of the storage layer, the second core wrap sheet being a second substrate for a second absorbent layer.

The first core wrap sheet is joined to the second core wrap sheet along at least one traverse sealing zone, the traverse sealing zone covering a total area, the storage layer, the first core wrap sheet, and the second core wrap sheet together comprise the first and second absorbent layers, and the absorbent particulate polymer material is deposited on the first and second substrates and thermoplastic adhesive material covers the absorbent particulate polymer material on the respective first and second substrates, the first and second absorbent layers combined together such that at least a portion of the thermoplastic adhesive material of the first absorbent layer contacts at least a portion of the thermoplastic adhesive material of the second absorbent layer, the absorbent particulate polymer material is disposed between the first and second substrates in an absorbent particulate polymer material area, and the absorbent particulate polymer material is substantially continuously distributed across the absorbent particulate polymer material area, wherein the traverse sealing zone provides a bond strength of at least about 1 N/cm between the first core wrap sheet and the second core wrap sheet as measured as tensile strength in the longitudinal direction, and wherein the traverse sealing zone comprises an open area of at least about 20% of the total area.
