Definitions

  • the present invention relates to a side-gusset bag. More particularly this invention concerns such a bag made from a laminate of plastic film and fabric.
  • a typical side-gusset bag has a front panel, a rear panel, and side gussets between the front panel and the rear panel and connected to the front and rear panels by respective edge folds.
  • the side-gusset bag is made of a plastic film/fabric laminate that comprises a polymer film on the outer surface of the bag and fabric connected to the polymer film and made of polymer ribbons on the inner surface of the bag.
  • the fabric and the polymer film on the outer surface of the bag are connected flatly to each other and form a fixed plastic film/fabric laminate.
  • the side-gusset bag that lies flat is closed on one end by a flap of the front panel, and side gusset flaps between the flap of the front panel and the rear panel and folded onto the rear panel to form a bottom gusset and connected thereto.
  • the front and rear panels form surfaces of equal size.
  • the designation of these bag surfaces as “front panel” and “rear panel” is intended to facilitate understanding of the teaching according to the invention, and not to present any technical restriction.
  • the bag surface onto which film flaps are folded and attached, thereby forming the bottom gusset is termed the “rear panel.”
  • the flattened side-gusset bag can be filled through the open end thereof, and is closed following filling.
  • the filled side-gusset bag is configured as a packaging bag, particularly for loose fill materials such as pelletized animal feed, litter for animals, or similar materials.
  • the side-gusset bag is particularly suitable for large packages that have a significant filled volume and a significant filled weight.
  • Corresponding side-gusset bags are also termed “side fold bags” in practice. No differentiation is made between these two terms in the context of the present invention.
  • Side-gusset bags made of single- or multi-layer films not reinforced by a fabric typically have a bottom face formed by welds.
  • the welds extend from a edge fold on longitudinal sides of the front or rear panels, at an acute angle, toward the bottom gusset.
  • the welds also termed “corner seals”, function such that the base of the side-gusset bag better forms a flat bottom face when the side-gusset bag is filled with a product.
  • the poor base shape also has negative influences on the volume of the container, because the fill height increases if the base does not sit correctly. This then needs to be taken into account by increasing the height of the bag.
  • the problem occurs particularly in the case of side-gusset bags that lie flat, and have deep side gussets that form rectangular packages after filling.
  • the fabric In order to make it possible to create welds on side-gusset bags manufactured from a plastic film/fabric laminate, the fabric must be equipped over its entire surface or at least sectionally with a coating capable of producing a weld—produced by way of example by an extrusion coating or by the application of a hot-melt glue.
  • a coating capable of producing a weld produced by way of example by an extrusion coating or by the application of a hot-melt glue.
  • coated fabrics made of uniaxially oriented polymer ribbons, and a coating made of a sealable polymer, for the purpose of producing bags is known from US 2010/0209024.
  • the coating of the fabric surface of a plastic film/fabric laminate material, for the purpose of improving the seal properties involves a complex manufacturing process, and requires an additional application of material that involves accordingly higher costs.
  • Another object is the provision of such an improved side-gusset bag made of a plastic film/fabric laminate that overcomes the above-given disadvantages, in particular that has a flat and stable bottom face after being filled.
  • a side-gusset bag made of a plastic film/fabric laminate has
  • the plastic film/fabric laminate has a polymer film on an outer surface of the bag and a fabric connected to the polymer film and made of polymer ribbons on an inner surface of the bag, and
  • a flap of the front panel and side gusset flaps between the flap of the front panel and the rear panel are folded onto the rear panel to form a bottom gusset to which they are connected.
  • corner weld seams bond the fabric surfaces of the side gussets on the inner surface of the bag to the adjacent fabric surfaces of the front panel or rear panel and an acute angle toward the bottom gusset.
  • the corner weld seams each have a structure with a grid pattern made of a plurality of punctiform or linear weld points.
  • the structure is generated by ultrasound welding.
  • the fabric and the polymer film are connected to each other and form a fixed laminate.
  • the fabric is untreated and does not comprise a sealable coating on the inner surface of the bag.
  • the fabric surfaces of the side gussets on the inner surface of the bag are connected to the adjacent fabric surfaces of the front panel or rear panel by corner weld seams that extend at an acute angle from a edge fold on longitudinal sides of the front or rear panels toward the bottom gusset. It is essential to the invention that the corner weld seams have a structure generated by ultrasound welding with a grid pattern consisting of a plurality of punctiform or linear weld points. A grid pattern made of a plurality of weld points one behind and adjacent to each other is advantageous.
  • the strength of the seam of the corner weld seams is the same in the longitudinal and transverse directions of the corner weld seams. Specifically, no significant brittleness arises at the seam edges of the corner weld seams, as can often be observed in the case of heat seals of polymer films produced using hot weld tongs.
  • the corner welds advantageously extend up to the bottom gusset.
  • the corner weld seams are oriented in such a manner that they form an angle between 30° and 60° with the bottom gusset.
  • the corner weld seams each enclose a equilaterally triangular surface together with the bottom gusset and one edge fold on the side.
  • the fabric of the plastic film/fabric laminate can particularly consist of a mesh of ribbon-shaped polymer strips.
  • the polymer ribbons of the mesh preferably have a width between 2 mm and 5 mm longitudinally and the transverse direction of the bag such that the polymer strips of the mesh, extending longitudinally and the transverse direction of the bag can also particularly have substantially the same width.
  • the corner weld seams are advantageously 2 mm to 10 mm wide and the grid pattern can have 10 to 500 weld points per surface area of 100 mm 2 .
  • the weld points of the corner weld seams are preferably on parallel lines oriented at an angle of 45° with respect to the longitudinal extension of the corner weld seams. In this case, at least three weld points are on each line, next to each other with equidistant spacing.
  • the plastic film/fabric laminate is typically made of polyolefinic components, and the polymer film on the inner surface of the bag is preferably a polypropylene film and particularly consists of a biaxially oriented polypropylene (BOPP).
  • the polymer film on the inner surface of the bag can consist of a polyester or polyamide (OPET, OPA).
  • the fabric on the inner surface of the bag comprises uniaxially oriented polymer ribbons woven together and welded on the surface thereof.
  • the fabric therefore is oriented in the longitudinal and transverse directions.
  • the lower edge of the front panel, the lower edge of the flanks of the side gussets adjacent the front panel, the lower edge of the flanks of the side gussets adjacent the rear panel, and the lower edge of the rear panel are advantageously offset with respect to each other in a fan shape such that the layers of the plastic film/fabric laminate folded along the bottom gusset each have a flap that directly abuts the rear panel and is preferably glued to the rear panel.
  • the side-gusset bag has a stable bottom face that forms a substantially flat and stable bottom surface following filling of the side-gusset bag.
  • the side-gusset bag according to the invention is suitable for large containers and for packaging of bulk goods with high bulk weight.
  • FIG. 1 is a front elevational view of the front panel of a side-gusset bag lying flat;
  • FIG. 2 is a rear elevational view of the rear panel of the side-gusset bag shown in FIG. 1 ;
  • FIG. 3 is a view of a detail of the inner surface of the bag of the side-gusset bag shown in FIGS. 1 and 2 ;
  • FIG. 4 is a large-scale view of a corner weld seam serving to shape the bottom face the side-gusset bag when filled;
  • FIG. 4 a is a large-scale view of the detail indicated at IVA in FIG. 4 ;
  • FIG. 5 shows the method of making the corner weld seam shown in FIG. 4 ;
  • FIG. 6 shows a side-gusset bag closed following the filling thereof, resulting in a package
  • FIG. 7 shows the profile of a cut edge of the film layers of a side gusset tube prior to gluing of the film layers to form a bottom face
  • FIG. 8 shows a variant of the subject matter as shown in FIG. 4 .
  • FIGS. 1 and 2 show a side-gusset bag lying flat, having a front panel 1 , a rear panel 2 , and side gussets 3 between the front panel and the rear panel and gussets connected to the front panel 1 and rear panel 2 by edge folds 4 .
  • the side-gusset bag is formed from a flat material web by folding. An overlap region 5 on the rear panel 2 in the embodiment is closed by gluing.
  • the side-gusset bag is open at its upper end and can be filled in machines with a loose bulk material.
  • the side-gusset bag has a closed lower end forming a flat bottom face when the side-gusset bag is filled.
  • the bottom face is formed by a flap 6 of the front panel, and side gusset flaps 7 between the flap 6 of the front panel 1 and the rear panel 2 and folded onto the rear panel 2 so as to form a bottom gusset 8 connected to the rear panel 2 .
  • corner weld seams 9 are made that extend at an acute angle from the outer edge fold 4 on the respective longitudinal outer edges of the front or rear panels 1 , 2 toward the bottom gusset 8 .
  • the corner weld seams 9 can form an angle between 30° and 60° with the bottom gusset 8 .
  • the corner weld seams 9 each enclose a equilateral-triangular surface, together with the bottom gusset 8 and one edge fold 4 on the side.
  • the side-gusset bag shown in the drawing is made of a plastic film/fabric laminate.
  • the plastic film/fabric laminate has at least two layers, and comprises a polymer film 10 on the outer surface of the bag and a fabric 11 connected to the polymer film 10 and made of polymer ribbons 12 and 13 on the inner surface of the bag.
  • the polymer film 10 is permanently glued to the fabric 11 .
  • the plastic film/fabric laminate is made for example of polyolefinic components.
  • FIG. 3 shows that the fabric 11 consists of a mesh of polymer ribbons 12 and 13 including longitudinal polymer ribbons 12 and transverse polymer ribbons 13 having a width for example between 2 mm and 5 mm.
  • the polymer ribbons 12 and 13 of the mesh have substantially the same width longitudinally of the bag and the transverse direction of the bag.
  • the method of making the corner weld seams 9 by ultrasound welding is shown in FIG. 5 .
  • High-frequency alternating current is produced by a generator and transmitted to an ultrasound converter that generates an ultrasonic vibration therefrom.
  • the high-frequency mechanical oscillations of a sonotrode 15 are transmitted under pressure to the polymer layers being connected.
  • the oscillations in ultrasound welding cause molecular friction and boundary surface friction in the joint zone.
  • the heat needed for the weld is created and the polymer material is plasticized at the weld points 14 .
  • counter bearings 16 for the sonotrode 15 engage laterally with the expanded side gussets 3 .
  • the ultrasound seal has the advantage that the welding times are short, and thermal energy is limited as much as possible to the contact regions such that other laminate regions, and particularly the oriented polymer ribbons 12 and 13 of the fabric 11 , are exposed to lower heat stress.
  • the corner weld seams 9 each have a width as shown in FIG. 4 , between 2 mm and 10 mm with a grid pattern advantageously of 10 to 500 weld points per surface area of 100 mm 2 .
  • the corner weld seam 9 is about 4 mm wide and is composed of about 100 weld points per surface area of 100 mm 2 .
  • FIG. 4 shows that the weld points 14 of the corner weld seams 9 are on parallel lines 17 oriented at an angle ⁇ of 45° to the longitudinal extension of the corner weld seams 9 . At least three weld points 14 are on each line 17 , next to each other with equidistant spacing.
  • a ventilation hole 24 is in at least one triangular bag flap 7 ′ bounded by a corner weld seam 9 .
  • An exchange of air is ensured between the bag flap 7 ′ formed with the ventilation hole 24 and the interior fill space of the side-gusset bag.
  • the exchange of air is indicated by arrows.
  • the exchange of air is possible because the corner weld seam 9 maintains a space between the bottom gusset 8 and the edge fold 4 on the longitudinal side of the bag.
  • the corner weld seam can for example be discontinuous in order to ensure or facilitate the exchange of air between the triangular bag flap 7 ′ and the fill space of the side-gusset bag.
  • the corner weld seams 9 provide a good base shape during filling of the side-gusset bag. After filling and the closure of its upper end, the side-gusset bag forms a substantially parallepipedal package with a flat, stable bottom face, as shown in FIG. 6 .
  • the side-gusset bag made of a plastic film/fabric laminate can be used for the package of loose bulk goods such as pelletized animal feed, litter for animals, or similar materials, and is suitable as a bag particularly for large packages that have a significant filled volume and a significant filled weight.
  • the bottom face must also be able to bear a great load during filling and during handling of the bag.
  • the material layers are preferably glued to each other. As regards the permanent glued bond, it is advantageous if the film layers being glued to each other to form a bottom face have an edge profile with the shape shown in FIG.
  • FIG. 7 shows a view of the rear panel 2 with a lower edge 18 of the front panel 1 , a lower edge 19 of flanks 20 of the side gussets 3 adjacent the front panel 1 , a lower edge 21 of flanks 22 of the side gussets 3 adjacent the rear panel 2 , and the lower edge 23 of the rear panel 2 are offset to each other in a fan shape.
  • the layers of the plastic film/fabric laminate folded along the bottom gusset 8 each have a flap that lies immediately against the rear panel 2 and is glued or welded to the rear panel 2 .
