Abstract
A form-fill-seal packing apparatus of the flow wrapper type accepts individuated items via in-feed conveyor. Items are moved through horizontal open lower-sided forming tube 10 by resting indirectly on an underneath transit conveyor, through the underside part of a continuous film bag forming from a supply of film around the forming tube, using a forming shoulder. The bag is longitudinally sealed beside the forming tube. Data may be printed on an upper film surface over a platen including an upper part of the forming tube. An outfeed conveyor carries transversely sealed wrapped items on to a vacuum sealer.
