ABSTRACT:
A method of packaging a rectangular moulded chocolate bar having a predetermined thickness, an upper face and a bottom face and bevelled longitudinal and lateral side faces, with a single sheet of heat sealable, composite multilayer material, by forming a longitudinal tube of the material completely around a bar with one longitudinal edge of the sheet projecting over another longitudinal edge and forming a covering flap, sealing the other longitudinal edge against an inner surface of the base of the covering flap, forming lateral folds which are first applied against the bevelled lateral side walls and then bent and applied on the ends of the bottom face, the lateral folds being made at each end of the tube, and folding the covering flap down over the bottom face in overlying relation to the lateral folds. The covering slap is sealed at least partially along a line parallel to a longitudinal edge of the flap, to provide a sealed and inviolable package.
