Abstract: A set of flat sheets of corrugated paper 101A, 102A, 101B, and 102B are provided. The flat sheets 101A and 102A can be folded into first and second packing elements 201A and 202A, respectively, and these packing elements 201A and 202A in turn can be assembled into a first packing 300A. The flat sheets 101B and 102B can be folded into third and fourth packing elements 201B and 202B, respectively, and these packing elements 201B and 202B in turn can be assembled into a second packing 300B. Then, the two packings 300A and 300B can be used, instead of conventional packings of Styrofoam, to hold opposed end portions or opposed side portions of a product 400 of a rectangular or similar shape that have different shapes. According to another aspect of the invention, other sheets 101C and 102C of corrugated paper can be prepared to produce other packing elements 201C and 202C, which in turn can be assembled into another packing 300C for holding one end portion or one side portion of a product of such a shape.

Abstract: A flat sheet 100 of corrugated paper is disclosed that can be folded into a package 200 for packing a fax machine or similar product.
