Patent Images
1. An absorbent article comprising:
- a liquid permeable cover layer;
a liquid impermeable barrier layer;
an absorbent core arranged between the cover layer and barrier layer comprising a mixture of superabsorbent polymer and adhesive, wherein the superabsorbent polymer is present in an amount of between about 50% to about 98% by weight and the adhesive is present in an amount between about 50% to about 2% by weight;
wherein the mixture extends continuously over a surface area of an adjacent layer in amount greater than 80% of a total surface area of the adjacent layer; and
wherein the mixture has a vertical delamination strength of greater than 9 N.
