A free-standing bag and a method for producing a free-standing bag from a thermoplastic synthetic film is disclosed. The bag includes a front panel and a back panel, which are connected to one another by lateral seams thus forming a filling opening, and in a collapsed state of the bag, having an inwardly folded base, whereby the inwardly folded base is comprised of a front panel fold as well as a back panel fold, both folds being sealed into the lateral seams, and whereby in the area of the inwardly folded base, an assembly strip is attached, which is made of a reinforced plastic film, and that the assembly strip terminates at a distance from the lateral seams, whereby a reinforcing strip is attached or glued to the inside and/or outside of the front panel and the back panel in the area of the filling opening.

1. A free-standing bag made of a thermoplastic synthetic film, comprising: a front panel;a back panel;lateral seams connecting the front panel with the back panel, thereby forming a filling opening, and in a collapsed state the bag has an inwardly folded base, the inwardly folded base including a frontpanel fold and a backpanel fold, the frontpanel fold and backpanel fold being welded into the lateral seams;an assembly strip being attached to the frontpanel fold and to the backpanel fold, the assembly strip being formed of a more rigid plastic film than the plastic film of the bag, the assembly strip terminating at a first distance from the lateral seams; anda reinforcement strip being attached to the front panel and the back panel in an area of the filling opening on an interior and/or exterior side, the reinforcement strip terminating at a second distance from the lateral seams,wherein a value of the second distance of the reinforcement strip from each lateral seam is at least that of a height of the base fold in a collapsed state. 2. The free-standing bag according to claim 1, wherein, in the area of the filling opening, the front panel and the back panel are double-layered. 3. The free-standing bag according to claim 2, wherein the reinforcing strip is glued to the inner side of the double-layered area of the front panel and the back panel. 4. The free-standing bag according to claim 2, wherein, in the area of the filling opening, a handle is formed or welded on. 5. The free-standing bag according to claim 1, wherein the assembly strip is glued to an inner and/or outer side of the base. 6. The free-standing bag according to claim 1, wherein a value of the first distance of the assembly strip from each lateral seam is at least that of a height of the base fold in a collapsed state. 7. The free-standing bag according to claim 1, wherein a value of the first distance of the assembly strip from each lateral seam is at least that of a height of the base fold in a collapsed state. 8. The free-standing bag according to claim 1, wherein a width of the assembly strip is equal to a width of the reinforcing strip such that the free-standing bag forms a box-shaped free-standing bag when the free-standing bag is in an unfolded state. 9. The free-standing bag according to claim 1, wherein the front panel and the back panel have a grip hole in the area of the filling opening, and wherein the grip hole extends through the front panel, the back panel, and the reinforcement strip. 10. The free-standing bag according to claim 1, wherein said first distance and said second distance are greater than zero. 11. The free-standing bag according to claim 1, wherein said first distance is equal to said second distance. 12. A method for producing a free-standing bag according to claim 1, the method comprising: conveying one or a plurality of horizontally spread-out webs of plastic film;adding and attaching the assembly strip and the reinforcing strip;folding the web of plastic film to form the front panel and the back panel;inserting the base fold; andforming the lateral seams by welding the web of plastic film. 13. A free-standing bag made of a thermoplastic synthetic film, comprising: a front panel;a back panel;lateral seams connecting the front panel with the back panel, thereby forming a filling opening, and in a collapsed state the bag has an inwardly folded base, the inwardly folded base including a frontpanel fold and a backpanel fold, the frontpanel fold and backpanel fold being welded into the lateral seams;an assembly strip being attached to the frontpanel fold and to the backpanel fold, the assembly strip being formed of a more rigid plastic film than the plastic film of the bag, the assembly strip terminating at a first distance from the lateral seams; anda reinforcement strip being attached to the front panel and the back panel in an area of the filling opening on an interior and/or exterior side, the reinforcement strip terminating at a second distance from the lateral seams,wherein, in the area of the filling opening, the front panel and the back panel are double-layered;wherein, a handle is connected to the double-layered area at least one connection location; andwherein the reinforcing strip is arranged above the welding for the handle inside the double-layered area between the at least one connection location and the filling opening. 14. The free standing bag according to claim 13, wherein a value of the second distance of the reinforcement strip from each lateral seam is at least that of a height of the base fold in a collapsed state. 15. The freestanding bag according to claim 13, wherein a width of the assembly strip is less than a width of the reinforcing strip such that a width of the free-standing bag in the area of the inwardly folded base is less than a width of the filling opening of the free-standing bag when the free-standing bag is in an unfolded state. 16. The free standing bag according to claim 15, wherein a value of the second distance of the reinforcement strip from each lateral seam is at least that of a height of the base fold in a collapsed state. 17. A free-standing bag made of a thermoplastic synthetic film, comprising: a front panel;a back panel;lateral seams connecting the front panel with the back panel, thereby forming a filling opening, and in a collapsed state the bag has an inwardly folded base, the inwardly folded base including a frontpanel fold and a backpanel fold, the frontpanel fold and backpanel fold being welded into the lateral seams;an assembly strip being attached to the frontpanel fold and to the backpanel fold, the assembly strip being formed of a more rigid plastic film than the plastic film of the bag, the assembly strip terminating at a first distance from the lateral seams; and a reinforcement strip being attached to the front panel and the back panel in an area of the filling opening on an interior and/or exterior side, the reinforcement strip terminating at a second distance from the lateral seams, wherein a width of the assembly strip is less than a width of the reinforcing strip such that a width of the free-standing bag in the area of the inwardly folded base is less than a width of the filling opening of the free-standing bag when the free-standing bag is in an unfolded state.
