A packaging container made of a plastic film. The packaging container includes a receptacle space for goods arranged between a front wall and a rear wall, an upper and a lower traverse seam which closes the packaging container on an upper and a lower end, respectively, connecting seams running between the upper and lower traverse seams, a film strip fastened to an internal side of the front wall via the connecting seams, a longitudinal channel formed by the film strip, the front wall and the connecting seams, and an engagement element arranged in the longitudinal channel. The engagement element is arranged transversely to a longitudinal extent of the longitudinal channel, and in a cross section above the film strip, to permit an engagement in the longitudinal extent of the longitudinal channel between the front wall and the film strip. The engagement element forms a handle with the front wall.
