An absorbent core comprising an absorbent material enclosed in a core wrap, wherein the core wrap comprises a liquid permeable substrate layer and wherein the absorbent material comprises about 87% to about 100% of superabsorbent polymer by weight of the absorbent material, wherein:
- a) the superabsorbent polymer is disposed in a plurality of frangible pockets in or on the liquid permeable substrate layer;
- and
- b) the core exhibits a material movement of about 0.2 cm or more, as measured with a Superabsorbent Material Movement Test.
An absorbent core comprising an absorbent material enclosed in a core wrap, wherein the core wrap a liquid permeable substrate layer and the absorbent material comprises about 87% to about 100% of superabsorbent polymer by weight of the absorbent material, wherein:
- a) the core comprises from about 0.5% to about 20% of an adhesive by weight of the core;
- and
- b) the core exhibits a material movement of about 0.2 cm or more, as measured with a Superabsorbent Material Movement Test.
An absorbent article comprising a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core disposed between the topsheet and the backsheet, wherein the absorbent core comprises a liquid permeable substrate layer and superabsorbent polymer, and wherein:
- a) (i) the absorbent core comprises from about 0.5% to about 20% of an adhesive by weight of the absorbent core;
- (ii) the superabsorbent polymer is disposed in a plurality of frangible pockets in or on the liquid permeable substrate layer;
- or (iii) both (i) and (ii);
- and
- b) the absorbent core exhibits a material movement of about 0.2 cm or more, as measured with a Superabsorbent Material Movement Test.
