A film-tail clamp, cut, and seal system for use in a wrapping apparatus for wrapping an associated item has an oval track vertically oriented and openable to move into and out of the associated item. A shuttle is configured for movement along an inner periphery of the track. A wrapping material is dispensed from the shuttle for wrapping around the item. A clamp arm, which is movable into and out of a plane defined by the film being wrapped around the item, has a sealing element for contacting and sealing a free end portion of the film onto a portion of the film already wrapped around the item. The clamp arm also has a clamp for securing the film when the film is sealed and has a cutter for cutting the free end portion of the film from the portion sealed onto the film.

A shuttle change system for use in a wrapping apparatus for wrapping an associated item is disclosed. The wrapping apparatus includes a shuttle that moves along the inner periphery of a track dispensing a wrapping material. The shuttle change system includes a carrier and a pair of track sections mounted to the carrier. The track sections are spaced from one another and parallel to one another, each adapted to support a shuttle. The carrier is moveable vertically, longitudinally and laterally to align either of the pair of tracks with the cantilevered base portion of the track. One of the tracks is adapted to receive a shuttle to be replaced and the other of the tracks is adapted to store a replacement shuttle for movement onto the track. The carrier is movable away from the track to permit the openable track portion to open and close without interference.

A protector for sheet metal coil is formed of plastic with a flange and sleeve which are joined together at a ridge portion. The protectors incorporate symmetrically disposed groupings of stacking features or components which include a finger within a stacking access opening, a stacking tab, and a stacking opening. The fingers are employed to resiliently engage the inner surface of a core of a coil and incorporate a receiver surface for freely abuttable engagement with a stacking tab of a second protector when arranged in mutual stacking relationship. The stacking openings function for stacking purposes to receive the protruding finger of a next stack protector.

A cling film system includes first and second film piles having different composition. Each film ply includes at least one cling layer and, desirably, one or more additional layers. Each film ply includes an overlapping portion and a second portion. The cling layer of the first film ply engages the cling layer of the second film ply in the overlapping portion of the first film ply and in the overlapping portion of the second film ply.
