The absorbent core comprises an absorbent layer comprising a central portion, a first side portion and a second side portion, a first folding guide between the central portion and the first side portion, and a second folding guide between the central portion and the second side portion. Each side portion comprises a plurality of winglets, each winglet having a proximal side relative to a folding guide and extending outward from this proximal side. Neighboring winglets are separated by a gap between their neighboring sides. When the absorbent core is folded along the folding guides, the central portion and the side portions form a three-dimensional basin and the gaps between the winglets decrease, the neighboring sides optionally coming into contact. The articles in the package are either bi-folded along a transversal fold line and are compressed at an In-Bag Compression Rate of from 5% to 50%, or the articles are tri-folded along a first fold line and a second fold line parallel to the transversal direction. ## Claims ### Claim 1 A package comprising at least one stack of compressed absorbent articles, wherein each absorbent article extends in a longitudinal direction and a transversal direction, and comprises: a topsheet; a backsheet; an absorbent core between the topsheet and the backsheet, wherein the absorbent core comprises an absorbent layer in a core wrap, the absorbent layer comprising an absorbent material and having a longitudinally extending central portion having opposing longitudinally-extending side edges, wherein each longitudinally-extending side edge comprises a recess, wherein the absorbent layer further comprises a first side portion disposed transversally outward of the central portion in a crotch region and a second side portion disposed transversally outward of the central portion on another side of the central portion in the crotch region; wherein the absorbent core further comprises a first folding guide between the central portion and the first side portion, and a second folding guide between the central portion and the second side portion; wherein each side portion comprises a proximal edge adjacent to a nearest folding guide and a distal edge laterally further outward from the nearest folding guide, and each side portion is completely encompassed within the recess such that the distal edge is laterally inward of longitudinally-extending side edge at a maximum width of the central portion; wherein each side portion further comprises a winglet; wherein each of the first folding guide and the second folding guide are substantially free of absorbent material; wherein each of the first folding guide and the second folding guide substantially continuously extend from a first location of a longitudinally-extending side edge of the absorbent core to a second location of the longitudinally-extending side edge of the absorbent core to separate each side portion from the central portion; wherein, when the absorbent core is folded along the folding guides, the central portion and the side portions, the side portions including the winglets forming upstanding sidewalls for a basin; and wherein in the package, the articles are folded and are compressed at an In-Bag Compression Rate of from 5% to 50%. ### Claim 2 (depends on 1) The package of claim 1, wherein the absorbent core is substantially free of cellulose fibers. ### Claim 3 (depends on 1) The package of claim 1, wherein the articles in the package have an In-Bag Stack Height of 72 mm to 120 mm. ### Claim 4 (depends on 3) The package of claim 3, wherein the articles in the package have an In-Bag Stack Height of 84 mm to 120 mm. ### Claim 5 (depends on 1) The package of claim 1, wherein the core wrap comprises a top layer and a bottom layer, and the top layer of the core wrap is bonded to the bottom layer of the core wrap through at least the folding guides. ### Claim 6 (depends on 5) The package of claim 5, comprising an auxiliary glue between (i) at least one of the top layer or bottom layer of the core wrap and (ii) the absorbent layer. ### Claim 7 (depends on 1) The package of claim 1, wherein each absorbent article further comprises a front elastic waist feature and/or a back elastic waist feature. ### Claim 8 (depends on 1) The package of claim 1, wherein each absorbent article further comprises a pair of barrier leg cuffs and/or a pair of gasketing cuffs. ### Claim 9 (depends on 1) The package of claim 1, wherein each absorbent article further comprises a liquid management layer between the topsheet and the absorbent core. ### Claim 10 (depends on 9) The package of claim 9, wherein the liquid management layer comprises folding guides that at least partially superpose the folding guides of the absorbent core. ### Claim 11 (depends on 1) The package of claim 1, wherein the articles are tri-folded with a first fold line and a second fold line, wherein one or both of the first and second fold lines are placed outside of the side portions towards a front edge and/or towards a back edge of the core. ### Claim 12 (depends on 1) The package of claim 1, wherein the topsheet is bonded to at least one folding guide. ### Claim 13 (depends on 1) The package of claim 1, wherein the topsheet is substantially planar across the central and side portions. ### Claim 14 (depends on 1) The package of claim 1, wherein each absorbent article further comprises elastic leg cuffs, configured to pull the side portions including the winglets upwards, hinging on the folding guides, to form the upstanding sidewalls for the basin.
