Abstract:
Substantially planar absorbent core (28) comprising at least 80% and up to 100% by weight of superabsorbent polymer as absorbent material on an absorbent material deposition area (73) and a core wrap. The absorbent material deposition area comprises at least one absorbent material-free channel-forming areas (26a,b) through which the top and bottom substrates (16, 16') of the core wrap are bonded together. An auxiliary glue (72) is applied directly at least to the inner surface of the first substrate on an auxiliary glue application area (71). The auxiliary glue application area (71) is smaller than the absorbent material deposition area (73) and the core comprises at least one C-wrap seal (284', 286') along at least one edge, in particular along the two longitudinally extending edges of the core.
