ABSTRACT:
A “protective structure of disc packaging” of the invention comprises a protective body placed on the top and the bottom sides of a pile of discs; a heat-shrink film covers the protective body and said discs together for avoiding the discs from deforming the heat-shrink film. The characteristic of the invention lies in: the protective body is composed of at least two interlaced disc-shaped plates, which are made of corrugated paper or plastic corrugated sheet with wavy buffer portions. 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 size of each disc-shaped plate is larger than the disc. The invention, therefore, is able to achieve the objectives of retaining the disc quality during the disc packaging and delivery processes, in addition, effectively reducing the disc packaging costs based on the requirement of environmental protection.
