具有通道形成区域和C形包裹密封件的吸收芯
摘要：
本发明公开了基本上平面的吸收芯(28)，该吸收芯在吸收材料沉积区域(73)上包括按重量计至少80％且最多100％的作为的吸收材料的超吸收聚合物、和芯包裹物。吸收材料沉积区域包括至少一个不含吸收材料的通道形成区域(26a,b)，芯包裹物的顶部基底和底部基底(16，16’)通过所述通道形成区域粘结在一起。辅助胶(72)在辅助胶施加区域(71)上至少直接施加到第一基底的内表面。辅助胶施加区域(71)小于吸收材料沉积区域(73)，并且芯沿至少一个边缘，具体地沿芯的所述两个纵向延伸的边缘包括至少一个C形包裹密封件(284’，286’)。
摘要（英）：

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.
