CORRUGATED FIBERBOARD, SHEATHING CORRUGATED FIBERBOARD CASE AND SIMPLE PACKAGING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To enhance recyclability of paper or the like by reducing the cost of a corrugated fiberboard, a sheathing corrugated fiberboard and a simple packaging structure. SOLUTION: The corrugated fiberboard having a three-layer structure is formed of a corrugating medium 7 formed of a material having a short mean fiber length of a part of the fiberboard specified according to the JIS used to form the sheathing corrugated fiberboard, a front liner 8 adhered to the one surface of the corrugating medium 7 and formed of the same material as that of the corrugating medium 7 and a rear liner 9 adhered to the other surface of the corrugating medium 7 and formed of the same material as that of the corrugating medium 7. Thus, since the fiberboard can be formed of a material having low quality and a low cost, the fiberboard has the low cost and since the use of recycled paper having low quality is expedited to enhance recyclability of the paper or the like.
