A packing apparatus for use in a sterile environment has an article loading and supply system. The loading system has a hatch in a first wall (P1) positioned at a height corresponding to a normal and ergonomic working height for an operator. The hatch faces an operating station which is to be supplied with the articles. A container element (2) has an internal volume (25) for containing articles, with a first article loading opening (21) and a second article unloading opening (22). The container element (2) is positioned in the sterile environment and is movable so that it can be positioned in a lowered position (PA) which corresponds to the hatch position for loading articles through the first loading opening, and then positionable in a raised position (PS) in which the second loading opening (22) is above the operating station (S1) for unloading the articles to be supplied thereto.
