Summary:The utility model discloses a composite paper tube. The first paper layer and the external paper layer sequentially cover the outside of the sealing layer, the sealing layer is formed by spirally winding a sealing film, the side walls of the sealing film are mutually pressed into a whole to form a pressing part, the first paper layer forms an accommodating groove for accommodating the pressing part on the outer side of the sealing layer, and the position of the accommodating groove corresponds to that of the pressing part. According to the composite paper tube, the containing groove is formed in the first paper layer close to the sealing layer and used for containing the press-fit part of the sealing layer, the problem that the press-fit part protrudes is well solved, and therefore the surface of the composite paper tube is smoother; the problems that the attractiveness of a manufactured packaging tin and the surface printing effect of the packaging tin are affected due to the fact that a protruding press-fit
