ABSORBENT PADS COMPRISING ZONES OF DIFFERENTIAL ABSORBENT CAPACITY

摘要

An folded absorbent sanitary pad having a higher basis weight of superabsorbent polymer in correspondence with the folding lines which helps reducing the risk of side leakage.

主权项

1. A folded absorbent pad (10) having, in its flattened unfolded configuration a central longitudinal axis (I) and a central transversal axis (II)
said pad (10) comprising: a topsheet (20), a backsheet (30) and an absorbent core (40) disposed between said topsheet (20) and backsheet (30), one or more folding lines (50) said absorbent core (40) comprising a storage layer (60) said storage layer (60) comprising SAP and comprising, in correspondence with the one or more folding lines (50), one or more folding portions (70) said folding portions (70) being defined as portions of the storage layer (60) overlapping said folding lines (50) and extending for from 3 to 20 mm on both sides of said folding lines along a direction perpendicular to said folding lines (50) wherein in at least one of said folding portions (70) the average basis weight of the SAP is at least 10 gsm higher than the average basis weight of SAP in the entire storage layer (60).
