In a packaging for a circular insertion tool, in particular a circular saw blade, with a planar main body, which has a holding flange for fixing an associated insertion tool on the planar main body, the planar main body has a polygonal outer circumference, with a tab which is bendable in the direction of the holding flange being arranged on at least one side of the polygonal outer circumference.

Provided is a package that suppresses stimulation of a corner portion formed after being individually divided. The package includes a first resin sheet including an accommodating portion that is a first recess in which an accommodated object is accommodated, and a second resin sheet covering the accommodating portion and having a welded region that faces the first resin sheet and is welded to the first resin sheet around the accommodating portion. At a corner portion in which a first side in a first direction appearing on a side surface of the welded region and a second side in a second direction appearing on the side surface of the welded region intersect, a non-welded region where the first resin sheet and the second resin sheet are not welded is provided. In the non-welded region, a gap is provided between a corner portion of the first resin sheet and a corner portion of the second resin sheet.
