A multi-wall tray is formed from a cut and scored blank of corrugated container board or the like. In cutting and scoring the blank all of the score lines are inclined at an angle, preferably 45 DEG , to the flute direction of the board. When the blank is folded to define the tray structure, the tray walls consist of plies of different flute orientation resulting in good stacking strength, at least ten per cent better than trays having normally oriented flutes in the corrugated board thereof. Moreover, there is a saving in board in orienting the blank therein in the fashion described.
