ABSTRACT:
A generally parallepipedal package comprised of a stack of goods sitting on a pallet has four horizontally directed sides, vertically oppositely directed top and bottom faces, and upper and lower horizontally extending edges meeting at upper and lower corners. It is wrapped by first securing an end of a stretch foil to the package adjacent the bottom face, then drawing the foil from one of lower corners of one of the sides diagonally across the one side to the diagonally opposite upper corner of the one side while maintaining the foil taut, and then laying the foil on and along the upper edge of the adjacent side extending perpendicularly from the one side to the opposite upper corner with the foil contacting both the top face and the one side. Subsequently the foil is drawn from the opposite upper corner of the other side diagonally downward across the side opposite to the one side to the diagonally opposite lower corner of the opposite side and then is laid on and along the lower edge of the adjacent side extending perpendicularly from the one side to the opposite lower corner.
