Abstract: A form-fill-seal machine and a method for manufacturing and filling a bag (100) having a drawstring tape or cord. The form-fill-seal machine includes a device to guide a film on the machine. A conveying device positions at least one drawstring tape or cord on the film. A folding device folds the film to form a first sheet and a second sheet of the bag. First and second welding jaws weld the first sheet and the second sheet to close two sides of the bag and leave a third side of the bag open. A filling chute fills the bag by the third side of the bag. Third welding jaws close the bag by sealing the third side.

Abstract: The invention relates to a method for manufacturing (S) a bag (3) by means of blown film extrusion, including the following steps: extruding (S2) plastic such as to form an annular film (2) including closing assemblies (10, 20), said annular film being intended to form the walls of the bag; and blowing (S5) the annular film such as to form a sheath, the complementary profile sections (14, 24) of each of the closing assemblies (10, 20) being integrally formed with a base (18, 28) connected to the annular film (2) via a connection rod (19, 29) that extends parallel to the longitudinal axis (X) between the annular film (2) and the base (18, 28) and is designed to keep the base (18, 28) separated from the annular film (2).

Abstract: The present invention relates to a bag including: two generally parallel sheets; matching closing profiles fixed on these sheets; a slider for actuating the profiles, this slider comprising flanks each inner surface of which bears a boss. This bag is remarkable by the fact that said sheets include on their outer faces, and outside said slider, abutment means capable of immobilizing said sheets relatively to said slider along a direction generally perpendicular to the displacement axis (X-X?) of the slider.

Abstract: A sachet has a body, the inner space of which is notably delimited by two sheets forming its main walls, and which includes complementary closing profiles respectively attached on these sheets as well as a cursor for actuating the profiles upon closing and opening, which comprises two longitudinal flanks connected by a base, as well as a longitudinal sole which extends from the base between the flanks, in order to delimit two opening/closing channels of the profiles. The cursor includes, longitudinally, in the extension of the base, a jutting-out element which extends beyond the flanks. The jutting-out element is positioned on the side of the cursor which corresponds to a closing direction of the profiles.

Abstract: The present invention concerns a bag comprising a closing assembly (100) comprising two complementary elements (110, 120) supported by respective webs (112, 122) at least one of which is integral with a film (10) at a zone (114) located not superimposed on the corresponding closing element (110) in order to allow articulation of said web (112) on the film (10), characterized by the fact that the articulated web (112) extends beyond the closing element (110) such that upon engagement of the closing elements (110, 120), the end (115) of the articulated web (112) bears on a structure (20) opposite it.

Abstract: The present invention relates to a fastener or closure assembly for fitting to a sheet or to the mouth of a packaging bag, and comprising at least one fastener or closure strip formed by a support web and a fastener or closure element carried by the web, the assembly including sequential cuts occupying a fraction of the width of the support web of the strip, outside the fastener or closure element and distributed over the length of the assembly in order to suppress the effects of warping, curving, or curling of the assembly.

Abstract: A packaging method includes the providing of a bag. A mouth of the bag may include an opening/closing for multiple successive openings and closings and a cleavable linking veil, located at a distance therefrom inside the bag in relation to the opening/closing. The method may also include introduction of contents to be wrapped in the bag and tightening of said bag in order to close it, with tension being applied to the contents. A veil may enter into contact with the contents to avoid the application of stress on the opening/closing, and guarantee free access to the contents via said opening/closing after tearing the cleavable linking veil. In one embodiment, free access to bag contents enables the bag to be relaxed in a closed state as a result of the distance (D) separating the veil and the opening/closing. The invention also relates to a packaging device and to bags thus obtained.

Abstract: The present invention relates to a bag (1) including: two generally parallel sheets (12, 13); matching closing profiles (2, 3) fixed on these sheets (12, 13); a slider (5) for actuating the profiles (2, 3), this slider (5) comprising flanks (51, 52) each inner surface of which bears a boss (53, 54). This bag is remarkable by the fact that said sheets (12, 13) include on their outer faces, and outside said slider (5), abutment means (6) capable of immobilizing said sheets (12, 13) relatively to said slider (5) along a direction generally perpendicular to the displacement axis (X-X?) of the slider (5).
