Zusammenfassung:	The utility model provides an edge sealing structure of a double-layer paper cup, and belongs to the technical field of paper cups. The strength problem of the double-layer paper cup is solved. The edge sealing structure comprises an inner cup layer and an outer cup layer, the thickness of the inner cup layer is larger than that of the outer cup layer, the outer cup layer adheres to the peripheral face of the inner cup layer, the inner cup layer and the outer cup layer form a sector after being unfolded, and the sector length of the inner cup layer is larger than that of the outer cup layer, so that the first end of the outer cup layer does not cover the edge of the first end of the inner cup layer. The edge, not covered by the first end of the inner cup layer, of the outer cup layer is an edge sealing area, and when the edge sealing area is in lap joint with the inner side face of the inner cup layer and forms sealing bonding, the first end of the outer cup layer, the second end of the outer cup layer, the s
