PROBLEM TO BE SOLVED: To prevent effectively the occurrence of tear with respect to diagonal tension, form pollution-free products, and enable disposal to be done simultaneously with corrugated board box at low disposal cost, and make it employable as paper making material by forming an unpacking and cutting guide tape adhered to the interior surface of a corrugated board box with paper and fold parts at the side in the longitudi nal direction. SOLUTION: Strip paper 4 is folded (in a coiled form) from its both sides in a manner being faced toward the reverse rotational direction mutually respectively so as to form fold portions 5, 5 at both sides in the longitudinal direction. In this case, since an adhesive layer 6 is available by applying adhesive on only one surface of the strip paper 4, so that a guide tape 2a can be manufactured with case. For such strip paper 4 to be used, a paper string or the like is given for example, an it is preferably to employ hemp-containing craft paper in particular. The width of the guide tape 2a is set preferably to be 3 mm-8 mm and its thickness to be 0.15 mm-0.3 mm. Accordingly, when the corrugated board box is opened, the tape undergoes no diagonal tear, and the cut portion need not to be fractionally disposed with the corrugated board box, thereby reducing personnel expenses.
