1. A plastic film bottom bag having a bag opening and an opposite bag end, comprising:
a plastic film front wall having a bag opening edge and a first side edge and an opposite second side edge,
a plastic film rear wall having a bag opening edge and having a first side edge and an opposite second side edge,
a first plastic film side wall having a bag opening edge and having a first side fold extending from or at a distance from the bag opening edge in the direction of the bag end or up to the bag end, the first plastic film side wall comprising, on either side of the first side fold, a first side wall section and a second side wall section which extend from the first side fold to the first side edge of the plastic film front wall and to the first side edge of the plastic film rear wall, respectively,
a second plastic film side wall having a bag opening edge and having a second side fold extending from or at a distance from the bag opening edge in the direction of the bag end or up to the bag end, the second plastic film side wall comprising, on either side of the second side fold, a first side wall section and a second side wall section which extend from the second side fold to the second side edge of the plastic film front wall and to the second side edge of the plastic film rear wall, respectively, and
a plastic film bag bottom having an inner side and an outer side,
wherein:
in a transition from the plastic film front wall to the first side wall section of the first plastic film side wall, the plastic film front wall and the first side wall section of the first plastic film side wall are welded to one another so as to form a seam that extends from the bag opening edge to the plastic film bag bottom, and/or
in a transition from the plastic film front wall to the first side wall section of the second plastic film side wall, the plastic film front wall and the first side wall section of the second plastic film side wall are welded to one another so as to form a seam that extends from the bag opening edge to the plastic film bag bottom, and/or
in a transition from the plastic film rear wall to the second side wall section of the first plastic film side wall, the plastic film rear wall and the second side wall section of the first plastic film side wall are welded to one another so as to form a seam that extends from the bag opening edge to the plastic film bag bottom, and/or
in a transition from the plastic film rear wall to the second side wall section of the second plastic film side wall, the plastic film rear wall and the second side wall section of the second plastic film side wall are welded to one another so as to form a seam that extends from the bag opening edge to the plastic film bag bottom;

wherein:
the first side fold comprises, in sections or completely, a first side fold welded seam extending from or at a distance from the bag opening edge up to the bag end, the first plastic film side wall comprising, on either side of the first side fold welded seam, the first side wall section which extends from the first side fold welded seam to the first side edge of the plastic film front wall, and the second side wall section which extends from the first side fold welded seam to the first side edge of the plastic film rear wall, and
the second side fold comprises, in sections or completely, a second side fold welded seam extending from or at a distance from the bag opening edge up to the bag end, the second plastic film side wall comprising, on either side of the second side fold welded seam, the first side wall section which extends from the second side fold welded seam to the second side edge of the plastic film front wall, and the second side wall section which extends from the second side fold welded seam to the second side edge of the plastic film rear wall; and

wherein:
the first side fold is an outwardly facing side fold welded seam, and
the second side fold is an outwardly facing side fold welded seam,

and wherein:
in a transition from the plastic film front wall to the plastic film bag bottom, the plastic film front wall and the plastic film bag bottom are welded to one another so as to form a hollow seam that extends from the first side edge to the opposite second side edge of the plastic film front wall, and
in a transition from the plastic film rear wall to the plastic film bag bottom, the plastic film rear wall and the plastic film bag bottom are welded to one another so as to form a hollow seam that extends from the first side edge to the opposite second side edge of the plastic film rear wall.
