Abstract
A discrete absorbent insert for use in a containment system includes an absorbent core positioned between a first sheet and a second sheet. The first sheet and the second sheet extend beyond the core and are joined together to form a seal. The absorbent core has at least 40% superabsorbent. The absorbent insert has an intake layer of at least 100 gsm between the first sheet and the absorbent core. The first sheet and the second sheet are fluid permeable, spunbond webs of synthetic polymer filaments. The absorbent insert has an absorbent capacity of at least 600 g. The discrete absorbent insert may have an intake rate for a first insult through the first sheet having a first value and an intake rate for a first insult through the second sheet having a second value, wherein a difference between the first value and the second value is less than 20%.
