The invention provides a tray, belonging to the field of stacking and wrappage. The tray comprises a blown tray body and a group of reinforced brackets, wherein the tray body is composed of a pair of panels and a first reinforced rib; the edge part and middle part of one side surface of one of the panels are respectively provided with a group of first supporting seats; one pair of wall bodies in wall bodies of each first supporting seat and the first reinforced rib form a cross relation; each reinforced bracket in the group of reinforced brackets is formed by a pair of reinforced bracket panels and a second reinforced rib; the two ends and middles of one side surface of the reinforced bracket facing to the panels in one group of reinforced bracket panels are respectively provided with a second supporting seat; a pair of side walls in the side walls of each second supporting seat and the second reinforced rib form a cross relation; and the second supporting seats and the first supporting seats are fixed mutually. The tray has the advantages of good combining effect, intensity and flexural strength resistance, thereby effectively prolonging the service life and increasing the stacking weight. In addition, the tray has the advantages of recoverability and environmental friendliness.
