A device for packaging preferably two-dimensional products is designed for forming a bag-like tube by way of a longitudinal connection device, from a web of packaging 5 material. The bag-like tube, with respect to a conveying direction of the packaging material, is open in a region in front of the longitudinal connection device and is closed in the region after the longitudinal connection device. The device comprises a suction device which leads 10 into the still open bag-like tube, and in the closed region comprises a suction opening, through which gas can be sucked out of the region after the longitudinal connection device, out of the bag-like tube and through the suction device. Either a section of the suction 15 channel cooperates with the longitudinal connection device for forming the longitudinal connection, or an arm leads into the bag-like tube and subsequently extends in the conveying direction up to the suction opening, wherein a region of the suction element which cooperates with the 20 longitudinal connection device for forming the longitudinal connection, is arranged outside the flexible bag-like tube.
