1. An absorbent core comprising a longitudinally folded multi-layer absorbent laminate, the longitudinally folded multi-layer absorbent laminate comprising:
a substrate laminate layer; and
an absorbent layer positioned and adhered on the substrate laminate layer, the absorbent layer containing super absorbent polymer (SAP);
wherein the longitudinally folded multi-layer absorbent laminate is folded to form a longitudinally folded multi-layer absorbent laminate of at least five layers of laminate; and
wherein the longitudinally folded multi-layer absorbent laminate has two lateral laminate sides and a width extending between the laminate sides, and:
a first one of the layers of laminate spans the entire width,
a second one of the layers of laminate has two portions that extend inwardly relative to the laminate sides to first folds that are separated from one another by a first lateral distance,
a third one of the layers of laminate has two portions that extend outwardly from the first folds toward the laminate sides to second folds, wherein the third layer of laminate is disposed between the first and second layers of laminate,
a fourth one of the layers of laminate has two portions that extend from the second folds inwardly relative to the laminate sides to third folds that are separated from one another by a second lateral distance, wherein the fourth layer of laminate is disposed between the first and third layers of laminate, and
a fifth one of the layers of laminate has two portions that extend outwardly from the third folds toward the laminate sides, wherein the fifth layer of laminate is disposed between the first and fourth layers of laminate;
wherein laterally opposing portions of each of at least the second and third layers define a longitudinally-extending channel above at least the first layer and between at least the first folds.
