A package formed of flexible polymeric film, containing a stack of folded disposable absorbent articles, the stack having an approximately rectangular cuboid shape and comprising: a plurality of the articles, similarly folded, each of the plurality of folded articles comprising two opposing faces lying along approximately parallel planes, and a fold with a fold nose; the plurality of the articles being arranged with one of the opposing faces of one in contact with one of the opposing faces of a next adjacent one, and wherein the fold noses of some or all of the plurality are disposed approximately along a first side of the cuboid shaped stack; a second side opposite to and approximately parallel with the first side; opposing third and fourth sides that are approximately parallel to each other and approximately perpendicular to the first and second sides; and opposing fifth and sixth sides that are approximately parallel to each other and approximately perpendicular to the fourth and fifth sides; a stacking direction approximately perpendicular to the parallel planes and to the fifth and sixth sides; and a stack length measured from a first outward-facing side of a first article in the stack to an opposing second outward-facing side of a last article in the stack, along the stacking direction; the flexible polymeric film enclosing and wrapping the stack and thereby approximately assuming the rectangular cuboid shape and forming the package, the package thereby having six outward-facing surfaces comprising: a first package surface having no seam thereacross; a second package surface opposite the first package surface, the second package surface having a seam extending thereacross; an opposing pair of third and fourth package surfaces, the third and fourth package surfaces each having a seam extending therealong; and an opposing pair of fifth and sixth package surfaces; the package having: a path of perforations or scoring in the film beginning at a first endpoint and ending at a second endpoint, the path defining a serpentine shape having a first curve that is convex with respect to a reference point, an inflection point, and a second curve that is concave with respect to the reference point, the serpentine shape being present substantially entirely on one of the six outward facing surfaces, a pair of adjacent flap structures being defined by the path of perforations or scoring comprising a first flap comprising a first terminal end defined by the first curve and a second flap comprising a second terminal end defined by the second curve, wherein each of the first flap and the second flap extend more than 50% of the width of the one of the six outward facing surfaces.
