Packing box (2) of polygonal general shape that widens out, is made from a flat cellular plastic blank that is cut and folded. The box (2) comprises a base (4) and side walls (5, 6) which are formed from side panels of the blank and are joined together, and an outer reinforcing frame (7), used for holding the box. The frame runs around the side walls (5, 6) and comprises frame members (8, 9) joined together and fixed to the side walls (5, 6). The frame members are formed from at least four flaps extending from side panels of the blank and rolled up spiral-fashion.
