1. An opposing-foil panel, comprising:
first and second planar foils each defining a foil height extending linearly along a machine direction between first and second foil ends, a foil width extending linearly along a cross-machine direction, normal to the machine direction, between first and second foil sides and an interior surface between the first and second foil ends and the first and second foil sides, the interior surface the first planar foil spaced apart from the interior surface of the second planar foil, a first zone between the first and second planar foils, the first zone defining a first zone length extending along the machine direction and coextensive with the foil height and a first zone width parallel to and extending in the cross-machine direction across a first portion of the foil width, a first plurality of elongated support members affixed to the interior surfaces of the first and second planar foils in the first zone, the first plurality of elongated support members extending along the first zone length in the machine direction and spaced apart along the first zone width in the cross-machine direction, a second zone between the first and second planar foils adjacent to the first zone, the second zone defining a second zone length extending along the machine direction and coextensive with the foil height and a second zone width parallel to and extending in the cross-machine direction across a second portion of the foil width, and a distributed interconnecting structure affixed to the interior surfaces of the first and second planar foils in the second zone and extending along the second zone length in the machine direction, the distributed interconnecting structure including a plurality of support members distributed across the second zone width with greater density than the first plurality of elongated support members is distributed across the first zone width. |
