The packing container has a plurality of side walls and both a top end wall and a bottom end wall. A plurality of upper and lower corner lugs are located at the intersection of the side walls and the end walls. A crease line which angles in toward the center of the bottom end wall is located between each lower corner lug and the bottom end wall such that upon formation of the packing container the crease line results in a portion of the laminate being displaced into the packing container to permit the bottom surface of the packing container to have an improved flatness. | |
