Abstract (en)

[origin: WO9966808A1] A method for manufacturing a tube, such as a straw, which is defined with a through hole therein, using starch, thereby preventing the tube from being hazardous to the human body and from generating environmental pollution. The tube is manufactured using an extruding process. In accordance with the present invention, air is blown into a through hole defined in a tube, being extruded, in order to prevent facing portions of the inner surface of the tube from coming into contact with each other, thereby preventing the through hole from being clogged.
