Abrégé

The invention relates to a flat-lying side-gusset bag made of a plastic fabric composite (2) and to a method for the production thereof. The side-gusset bag has opposing front walls (3a, 3b), side gussets (4a, 4b) introduced in between said front walls (3a, 3b), and folding edges (5) between the front walls (3a, 3b) and the side gussets (4a, 4b). Peripheral sections of the plastic fabric composite (2) are connected together in an overlapping region (10) at a longitudinal seam, wherein the plastic fabric composite (2) has a plastic fabric (7) and at least one closed plastic layer. The side gussets (5) extend, in the case of the flat-lying side-gusset bag, in each case over at most 1/3 of the width of the front walls. According to the invention, the overlapping region (10) is arranged off-centre on one of the front walls (3a, 3b) at least partially over one of the side gussets (4a, 4b) or at one of the side gussets (4a, 4b). In order to be able to form such a side-gusset bag, in the production method, first of all a closed, two-layer tube (12) is formed, from which a side-gusset tube (1) is subsequently formed.

Abrégé

A bag has two juxtaposed face panels of plastic film and each having two parallel side edges and top and bottom edges. A gusset extends between one of the side edges of one of the panels and the juxtaposed side edge of the other of the panels. The gusset is movable between a folded-in condition lying mainly between the panels and an extended condition projecting laterally past the panels and forming a spout generally at the top edges. A slide fastener at the top edges has two profile strips that can be locked to each other and that each have an attachment flap, and a slider shiftable along the profile strips in a closing direction to close the strips together and in an opposite opening direction to separate the strips. Joints secure the attachment flaps directly to inner faces of the respective face panels at the respective upper edges.
