Pocket folding edge of pocket type plastic information bag

The invention provides a pocket folding edge of a pocket type plastic information bag, which mainly comprises a plastic information bag body, and an upper pocket piece and a lower pocket piece which are oppositely folded from the top edge and the bottom edge are respectively arranged on the upper side and the lower side of the plastic information bag body. The invention is mainly characterized in that the folding edges of the upper pocket piece and the lower pocket piece are pressed by a plurality of spaced protruding part devices, and a plurality of spaced local relative deep pressing areas are formed at the folding edges. By means of the method and the structure, due to the fact that pressure is applied to the plastic information bag body through the discontinuous protruding parts, even if the pressure is applied to the weak position of the material of the plastic information bag body, continuous and linear damage cannot be generated to the plastic information bag body, and at most point-shaped breakage (di
