A stackable plastic box blank (30) constructed using a reinforcing net (2) made of first plastics material of rubber-modified polypropylene to form strong hinges, and a second plastics material (e.g) polypropylene, polythene) injection moulded in the spaces between elements of the net to form panels and flaps. The first plastic has a melt index less than the second plastic. The different second plastic characteristics enable additional column support to be provided. The structure of the box also reduces the forces on its structural walls by the provision of load bearing panels (42, 46, 62, 66). These load bearing panels are provided with convex projections of concavities which snap fit into rectangular openings in the end panels (44, 64). Base panel (58) and lid flaps (50, 58) are provided with concavities to provide anti-slip with adjacent boxes when in either the erected or collapsed state.
