An electronic cigarette cartridge tube and a method for preparing the same is introduced herein. Both of a filter tip and a cartridge container of the electronic cigarette cartridge tube are made respectively by consistent-and-continuous production machines used with a pulp-molding fabrication approach which is researched and improved, thereby integrally forming a solid geometrical shape of any one of the filter tip and the cartridge container. It can not only resolve the technical problems of the existing pulp-molding fabrication method that is incapable of producing a component (e.g. a cylinder-shaped longitudinal filter tip or cartridge container) of a cylinder-shaped lengthwise electronic cigarette cartridge tube, having a ratio, greater than one, of a maximum longitudinal height thereof being relative to a maximum transverse width thereof, but can also save its working cycle time, benefit its mass production, and assure its higher product yield and quality.
