A box having a base wall having an outer surface defined by a central region of a folded sheet, and one or more side walls forming a closed perimeter and extending from an inner surface of the base wall. Each side wall has spaced apart inner and outer layers being defined by a folded tab of the folded sheet, the folded tab defining an enclosure. A reinforcement ring is received in the enclosure defined by the folded tabs of the side wall(s). The reinforcement ring has a thickness greater than that of the folded sheet. A method of forming a box is also discussed. |
