Abstract
A multilayer corrugated board which can be smoothly bent from a planar state to a curved state without failure even at small radii of curvature, as well as a container made from such board. The materials and mechanical properties of the layers of the board are selected such that each layer inward of the outermost layer in the bent state buckles simultaneously and reversibly between each flute of the adjacent innermost corrugated layer.
