A method of packaging snack food chips, the method comprising the steps of: a) providing a plurality of snack food chips as a shingled assembly of the snack food chips supported on an elongate support which extends along and beneath the shingled assembly, the elongate support having a free end; b) enclosing the shingled assembly supported on the elongate support within an elongate packaging container having a closed end by pushing the elongate packaging container over the shingled assembly supported on the elongate support, the free end of the elongate support being located towards the closed end of the elongate packaging container, wherein the elongate packaging container and the shingled assembly supported on the elongate support are substantially horizontal during the enclosing step (b); c) vibrating the shingled assembly supported on the elongate support so as to cause the snack food chips sequentially to fall from the free end of the elongate support into the elongate packaging container while, during the vibrating, progressively translationally separating the closed end and the free output end so as progressively to form a shingled stack in the elongate packaging container extending away from the closed end, wherein at the commencement of the vibrating in step (c), the elongate packaging container and the shingled assembly supported on the elongate support are substantially horizontal, and wherein in step (c) the vibration is along an axis which is parallel or aligned with the elongate support; and d) during at least a part of step (c), during the vibrating and while progressively translationally separating the closed end and the free end, rotating simultaneously the elongate support and the elongate packaging container so that the closed end is lowered and an angle of inclination of the shingled stack to the vertical is decreased while at least a part of the shingled stack is being progressively formed. a) providing a plurality of snack food chips as a shingled assembly of the snack food chips supported on an elongate support which extends along and beneath the shingled assembly, the elongate support having a free end; b) enclosing the shingled assembly supported on the elongate support within an elongate packaging container having a closed end by pushing the elongate packaging container over the shingled assembly supported on the elongate support, the free end of the elongate support being located towards the closed end of the elongate packaging container, wherein the elongate packaging container and the shingled assembly supported on the elongate support are substantially horizontal during the enclosing step (b); c) vibrating the shingled assembly supported on the elongate support so as to cause the snack food chips sequentially to fall from the free end of the elongate support into the elongate packaging container while, during the vibrating, progressively translationally separating the closed end and the free output end so as progressively to form a shingled stack in the elongate packaging container extending away from the closed end, wherein at the commencement of the vibrating in step (c), the elongate packaging container and the shingled assembly supported on the elongate support are substantially horizontal, and wherein in step (c) the vibration is along an axis which is parallel or aligned with the elongate support; and d) during at least a part of step (c), during the vibrating and while progressively translationally separating the closed end and the free end, rotating simultaneously the elongate support and the elongate packaging container so that the closed end is lowered and an angle of inclination of the shingled stack to the vertical is decreased while at least a part of the shingled stack is being progressively formed.
