A precut plate for defining an assembly of plate parts is capable of taking at least first and second shapes. A first flat shape, wherein the plate as a whole is substantially in a plane and a second folded shape, obtained after folding about hinge parts of the plate one relative to the others to define a hollow volume, for example all or part of a package for products. The plate includes at least three layers stacked on one another. The second layer located between the first and the third layer is a flexible material layer, at least the first of the two first and third layers being a relatively rigid layer. The invention also concerns the resulting volume or package, and the method for making the plate.
