It is available, for the garbage assembling issue of the disposed empty PET bottles, that PET bottle could be folded up easily and effectively by both hands. Then, based on the geometrical theory of cylindrical Origami proposed by Nojima, we designed some kinds of CAD model of PET bottle with regular folding lines in circular direction and evaluated the function of folding up for axial compressive loading by CAE. Two main useful results are obtained as follows. One is that the empty PET bottle with the configuration of inclined main folding lines could be folded up by hands. The second is that the PET bottle in full, with the configuration above mentioned, could have the stiffness necessary for keeping in a pile of bottles' case and vending machine by the effect of increased internal pressure which is loaded on the folding surface of the bottle wall.
