Abstract: A lightweight, shock-absorbing package for carrying, shipping or mailing fragile articles is provided that is formed from a relatively stiff substantially flat sheet having front and back faces. The flat sheet has two fold lines disposed proximal to a centerline of the sheet, the fold lines dividing the flat sheet into a first section, a spine section, and a second section. The package includes at least one shock-absorbing resilient member made of lightweight, flexible material and attached proximal to three edges of the back face of the second section, one of the edges being opposite from and two being perpendicular to an edge of the spine section, of sufficient length to completely close the three open edges of a closed rectangular package formed when the flat sheet is folded back along its two fold lines to bring the back face of the first and second sections into a facing arrangement. A package composed of a resilient member that is glued or shrink-wrapped between two flat sheets is also provided.
