Protective structure of disc packaging

A "protective structure of disc packaging" of the invention is composed of an upper lid, a lower lid and a casing that are formed on the top and the bottom sides and the perimeters of a pile of discs, and a heat-shrinkable film covers the protective body and said discs together to retaining the disc quality during the disc packaging and delivery processes. The characteristic of the invention lies in: the upper lid and the lower lid are respectively composed of at least two interlaced disc-shaped plates, which possess wavy buffer portions that are made of corrugated paper or plastic corrugated sheet. When the upper and the lower disc-shaped plates are disposed, the undulating buffer portions of the disc-shaped plates are vertically stacked up, in addition, the sizes of the disc-shaped plates are larger than the sizes of the discs and the casing being shaped as a roll.
