A gusset bag (10) is formed of a pair of flat surface parts (12A and 12B) facing each other, and side gusset parts (14) folded to the inside of the bag. The gusset bag (10) has side heat-sealing portions (16A) at which the sides of the flat surface part (12A) and sides of the side gusset parts (14) are joined at the inner surfaces thereof, side heat-sealing portions (16B) at which the sides of the flat surface part (12B) and the other sides of the side gusset parts (14) are joined at the inner surfaces thereof, and closing sealing portions (18) at which the side heat-sealing portions (16A) and the side heat-sealing portions (16B) are joined at the outer surfaces of the side gusset parts (14) by ultrasonic sealing. With this configuration, in the gusset bag (10), it is possible to easily close the gusset parts, while preventing film pieces or dust from entering the bag in a step of closing the gusset parts.

A method for sealing and cutting of a flexible material for forming a flexible container comprising a product volume and at least one structural support volume can include feeding at least two flexible material into a sealing apparatus comprising a sealing surface and an opposed anvil surface; contacting a seam region of the at least two flexible material with the sealing surface to form a seal in the seam region and cut the seal to form a seam in a single unit operation. The seal defines one or both of at least a portion of a boundary of the product volume and at least a portion of a boundary of the at least one structural support volume.

The invention relates to a method for forming at least one bottom on a hose piece (20), which comprises plastic material, wherein at least one end of the hose piece is pulled open along at least one first folding edge (21), a bottom rectangle (22) and triangular pockets (23) thus being formed; wherein side tabs (25, 26) of the bottom rectangle are folded back along two folding edges (24) spaced apart from the first folding edge in order to close the bottom, wherein the two side tabs then contact each other; and wherein a bottom cover sheet (31) is applied to the bottom and is connected to the side tabs and at least one triangular pocket by application of heat or by means of a glue. The surfaces of the side tabs that come into contact and the triangular pockets are connected to each other at least in the region of the two folding edges, a connection (32) thus being formed.

Die Erfindung betrifft eine Anlage zum Herstellen eines Medizinprodukts, vor allem in Gestalt eines Ostomiebeutels, sowie ein Verfahren zum Betreiben einer solchen Anlage. Konventionelle Anlagen führen verschiedene Folienanlagen in verschiedenen Ebenen im Abstand zueinander und ermöglichen dadurch Vorarbeitsschritte. Dann werden die Folien in einer Ebene zusammengeführt und miteinander verschweißt. Die hier vorliegende Erfindung stellt ein hoch flexibles modulares Anlagenkonzept vor, bei welchem einzelne Zuführlinien für Halbzeuge vorgesehen sind. Die Zuführlinien können Halbzeuge vorkonfektioniert an eine Hauptlinie übergeben. In der Nauptlinie erfolgt unter größtmöglicher Arbeitspräzision das letztendliche Verarbeiten der Halbzeuge zum fertigen Produkt oder zu einem weiteren Halbzeug.
摘要:
A method of making a storage bag comprising the following steps performed in any order: (a) forming a composite tube having an inner surface comprising a higher melting polymer, an outer surface comprising a lower melting polymer, two ends, and a diameter; (b) flattening the tube in a direction perpendicular to the diameter; (c) forming a joint at one of the ends at a temperature between respective melting points of the higher melting polymer and the lower melting polymer; (d) providing a composite sheet having a first side comprising a higher melting polymer and a second side comprising a lower melting polymer; and (e) disposing the composite sheet over the joint such that the first side comprising a lower melting polymer engages the joint and forming a lap seam over the joint at a temperature between respective melting points of the higher melting polymer and the lower melting polymer, and a storage bag made by such method.
摘要:
The method serves for producing flexible packaging products, more particularly packaging bags, the packaging products being formed by welding together two film layers. In order to avoid imprecisions in the sequence of process steps, film sections (4) formed of film layers are separated from a film web (7a; 7b) and transferred to a transport device (1) where they are positively fixed at least at one edge by means of a fixing device (3). Then the film sections (4) are transported by means of the transport device (1) in a transport direction (5) to at least one welding station (12) while maintaining the positive fit, the film layers are welded together in the latter, and the film sections (4) are subsequently further transported while maintaining the positive fit.
摘要:
A packaging unit for hygiene articles is formed from a sheet of material having an inner surface and an outer surface. The inner surface includes an edge zone including an inner edge portion and an outer edge portion. The sheet has at least one folding axis dividing the sheet into a first region and a second region. The inner edge portion and the outer edge portion of the edge zone of the first region is provided with adhesive, and the other of the inner edge portion and the outer edge portion of the edge zone of the first region is adhesive-free. Further, one of the inner edge portion and the outer edge portion of the edge zone of the second region is provided with adhesive, and the other is adhesive-free in a complementary manner to the edge zone of the first region.
