The present invention provides a box-shaped packaging material which is assembled by using a conventional automatic assembling device, is hard to deform even after made into a box shape, and uses a sheet member to which a lenticular lens is attached. The box-shaped packaging material comprises: a sheet member having a lenticular lens attached thereto and provided with long and narrow semicircular convex lenses arranged on a radial direction on one surface thereof; an axial folding line formed in a direction of the convex lenses on the sheet member; and a radial folding line arranged in a direction perpendicular to the axial folding line. The box-shaped packaging material can be assembled by folding along the axial folding line and the radial folding line in a prescribed order. Strength of folding the axial folding line is adjusted in a range of 180-250 g, and Strength of folding the radial folding line is adjusted in a range of 220-300 g. |
