A method and apparatus for stretch wrapping a load with a film web having a tacky surface and a non-tacky surface. The film web is wrapped around the load in a forward direction with the tacky surface facing away from the load. The orientation of the film web is reversed by inserting a metal rod in the path of the film web and reversing the wrapping direction. The film web wraps around the metal rod, thereby causing the film web to fold back on itself. The film web is wrapped around the load in the reverse direction to cover the film web which was wrapped in the forward direction, with the tacky side facing the film web which was wrapped in the forward direction.
