A plastic film bag (1) has an opening, which can be optionally reclosed in the area of the bag's upper end (5), is sealed at its bottom end (10) and has a lateral gusset on a lateral wall (8). Said lateral gusset is comprised of a folded sheet (4), which is provided with an upper edge (9) and with lateral edges. The lateral edges of the folded sheet, with their inner sides, rest against and are joined to the inner sides of the front sheet (2) as well as of the rear sheet (3) of the bag on their lateral edges (8). The lateral gusset terminates in a closed manner, with the upper edge (9) of its folded sheet, underneath the upper end of the bag (5), and above the end (9) of the lateral gusset, the front sheet (2) and the rear sheet (3) are directly joined at the lateral edge. The inventive bag is characterized in that on the upper end of the lateral gusset, the folded sheet (4), with its outer side, is folded onto its other outer side and is joined to itself at the upper edge (9) that forms the upper lip of the lateral gusset. |
