In a sealing/parting means for the side weld (42) of a film semi-tube (13) of shrink film, in which items (16) are wrapped, the film web (19) consisting of two sandwiched films is fed to a transport and supporting system (18) comprising two opposing transport belts (21, 22) where it runs along an elongated, skid-shaped contact surface area (34) of a heated sealing/parting knife (20), resulting in the immediate welding zone of the film being preheated before it is fed at the end of this contact surface area to a sealing/parting blade (36) which parts and welds the film. The sealing/parting blade (36) has a constricting cutting gap.
