Abstract:
1. A laminate absorbent core comprising a first laminate layer comprising a first substrate layer and superabsorbent polymer particles forming multiple stripes on the first substrate layer and a second laminate layer comprising a second substrate layer and superabsorbent polymer particles forming multiple stripes on the second substrate layer wherein a first adhesive is at least applied between the first laminate layer and the second laminate layer and the superabsorbent polymer particles are immobilized by the first adhesive, wherein the stripes of the superabsorbent polymer particles on both the first substrate layer and the second substrate layer are spaced apart from each other to form gaps that are substantially free of superabsorbent polymer particles, wherein the first laminate layer and the second laminate layer are positioned on each other such that the superabsorbent polymer particle stripes of the second laminate layer are overlaying the gaps in the first laminate layer and the superabsorbent polymer particle stripes of the first laminate layer are overlaying the gaps in the second laminate layer and each gap in the first laminate layer is wider than the corresponding superabsorbent polymer particle stripe of the second laminate layer above the gap and each gap in the second laminate layer is wider than the corresponding superabsorbent polymer particle stripe of the first laminate layer below the gap, such that the stripes of superabsorbent polymer particles of the first laminate layer do not contact the stripes of superabsorbent polymer particles of the second laminate layer; the superabsorbent polymer particles making up more than 90% by weight of the total amount of material comprised between the first substrate layer and the second substrate layer, wherein the laminate absorbent core has a peak swelling restriction pressure from 50 N/m
