ABSTRACT:
A load is stretch wrapped with a sheet of stretch wrap packaging material by adhering a leading end portion of the sheet to a holding member, dispensing the sheet from a stretch wrap dispenser, and providing relative rotation between the dispenser and the load to wrap the sheet of stretch wrap packaging material on a load. The leading end portion of the sheet is released from the holding member, and a trailing end portion of the sheet is adhered to the holding member. The packaging material between the load and the holding member is severed while being held by the holding member. The sheet of stretch wrap packaging material is held in place against the holding member with a vacuum or by a tacky surface. The severing is accomplished by a hot wire on the holding member.
