An apparatus and method for stretch wrapping of a palletized load uses film tension feedback derived from a film tension control load cell to control film dispensation. The load cell measures film tension and the film payout rates is determined by the film tension. Film tension values are used to determine when an out of bounds condition occurs, namely, when a film break has occurred, or when a possible film break is about to occur or when the film has been cut at the end of a wrapping cycle. To prevent film free end entanglement caused by a break, clamps engage the film so the film tail is controlled, eliminating the risk of recoil. The broken film tail may then be quickly and reliably reattached to the rotating load in a desired position.
