A packing box for improving reinforcing force with a double-pad is provided to prevent damage of the contents generated when the box stacked at the lower layer is crushed or inclined and collapsed down by keeping excellent bearing power against load. The packing box for improving reinforcing force with a double-pad is formed by contacting and combining the lower and upper ends of case-shaped upper and lower plate bodies(10,40) with the same standard, to each other. An upper plate supporting pad(20) lower than the height of a lateral side of the upper plate body is erectly fitted into the upper plate body. An upper plate pad(30) having integrated lateral and bottom sides is closely fitted and fixed in the upper plate supporting pad. A lower plate supporting pad(50) higher than the height of a lateral side of the lower plate body is erectly fitted into the lower plate body. A lower plate pad(60) having integrated lateral and bottom sides is closely fitted in the lower plate supporting pad and protruded toward the upper side of the lower plate body correspondently to the embedded height of the upper plate body. |
