Definitions
- the invention relates to a foil pouch which is formed by folding a foil, has a front surface, a back surface, an inserted first side fold and an inserted second side fold and is closed by a longitudinal sealing seam and a top seal seam, wherein a reclosable strip is attached to the inner surface of the film bag underneath the top seal, releasably connecting the first side gusset to the adjacent front and back surfaces of the bag, wherein the outer edges between the first gusset and the adjacent front or rear surface consist of folding edges, wherein the first gusset forms a resealable chute when a bag portion above the reclosing strip is torn open for filling removal along a line of weakness contained in the film, and wherein the film consists of an at least two-layer composite film having a layer of a sealable plastic on the inside of the bag and a layer of a non-sealable material on the outside of the bag.
- a film bag with the described structure is suitable for the packaging of bulk material, such as dry food for animals, and has a reclosure, which allows the contents of the package in portions, ie pour out in portions or remove.
- the removal takes place through an opening in the first gusset, wherein the gusset after opening the Reclosable is removable and can be used as a chute.
- the opening is resealable.
- the reclosure can be carried out as a so-called zipper closure, which has strip-shaped tongue and groove elements, which can be manually connected to each other by pressure and then form a snap or clip connection.
- Other reclosures, z As Velcro closures or reclosures with a self-adhesive strip, are conceivable.
- a foil bag with the features described above is made WO 2004/092025 A2 known. It consists of a film folded into a tube. The hose produced by folding has on-side gussets and is closed on the shell side by means of a longitudinal sealing seam. Affixed to the inner surface of the film bag is a reclosable strip which removably connects one of the gussets to the adjacent front and back surfaces of the bag. The reclosure strip is longer than the width of the gusset and is secured to the insides of the gusset as well as the adjacent bag surfaces that form the front and back surfaces of the bag. The top seal closes the upper edge of the film bag and extends as a straight seal over the entire width of the film bag.
- a bag section is torn open along a line of weakness above the reclosure located on the inside of the bag.
- the disadvantage is that forms an opening in the film bag after the separation of the film section, which extends from the reclosure vertically up to the upper edge of the film bag and can not be closed.
- Another disadvantage is the unsatisfactory dimensional stability of the film bag. In use, the chute opens very far, the bag largely loses its shape on the sampling side. Due to the low dimensional stability, the handling of the opened bag is difficult. Especially with large bags requires handling of the opened bag and the metered removal of contents considerable skill of the user.
- a gusseted bag with a reclosable withdrawal opening in a side gusset there is known a gusseted bag with a reclosable withdrawal opening in a side gusset.
- the top seal is a straight seam and closes the top edge of the foil pouch.
- another horizontal seam is provided, extending from the outside of the second gusset to the ends of the reclosure strip attached to the inside of the front and back surfaces. Since this seal seam is adjacent to the ends of the reclosure, the bag is relatively tight in closed reclosure even in use.
- the gussets consist of separate, V-shaped folded film strips, which are inserted between the front surface and the rear surface of the bag and connected by longitudinal sealing seams.
- Resealable foil pouches which are used, for example, for packaging animal dry food, in practice consist of high quality composite films comprising a readily printable polyester outer layer, a sealable polyolefin innerliner, and often a metallic one Intermediate layer with a good barrier effect with respect to oxygen and water vapor.
- the problem is the weakening line. It is often formed in the known foil bags as a perforation, which is permeable to air.
- the reclosure which is arranged in the interior of the film bag, likewise does not constitute a gas-tight closure, so that the contents can dry out during prolonged storage and the product properties of the contents can change.
- a resealable foil bag with the features of the preamble of claim 1 is from the older, but not previously published WO 2007/047393 A2 known.
- the invention has the object to improve the performance of plastic bags.
- the film bag should be particularly easy to open and be easy to handle when removing contents.
- the weakening line consists of an embossing line produced by heat-sealing and a laser seam of congruent design.
- the inventive combination of a laser seam with a heat-sealed embossing line results in a line of weakness, which is characterized by a very good tear behavior.
- the tearing is smooth and takes place with a defined propagation along the weakening line. Because of the laser ablation on the outer layer of the Composite film is limited, the weakening line remains airtight. The permeation of oxygen and water vapor through the area of the line of weakness is negligible. Where the line of weakness reaches the folding edges reinforced by longitudinal sealing seams, notches are provided in the longitudinal sealing seams for crack initiation.
- the weakening line can extend parallel to the reclosing strip and an adjoining transverse seam, which closes the filling material space on the upper side, over the entire width of the film bag up to the edges of the second side fold. In the context of the invention, however, it is also the case that the weakening line extends parallel to the reclosing strip and then ends with a vertical section towards the top-seal seam.
- the reclosure in the first gusset of the foil bag is exposed.
- the gusset can be unfolded as a chute, resulting in a pouring opening, which is at least twice as long as the width of the gusset.
- the large opening facilitates the removal of lumpy contents.
- the provided for edge reinforcement longitudinal sealing seams give the film bag in the open state a considerable dimensional stability, so that a good handle of large plastic bags is guaranteed.
- the longitudinal sealing seams provided for edge reinforcement can be recessed in the area of the self-locking strip. On the tightness of the film bag, this has no effect, since the outer edge of the first side fold folding edges and additionally attached longitudinal sealing seams have no sealing function.
- the reclosure strip preferably forms a zipper closure and has a film carrier attachable to the inner surface of the bag the strip carrier molded strip-shaped closure elements.
- the strip-shaped closure elements are manually latched together by pressure in the manner of a tongue and groove connection.
- the film carrier is expediently connected with two sealing seams, which are arranged on both sides of the strip-shaped closure elements, with the film forming the film bag.
- the foil pouches are manufactured as flat-laid pouches and filled with filling material later in filling systems, which is filled at the upper end of the pouch, for example, by a bottom-side opening or, before attachment of the head sealing seams.
- the flat foil bags are stacked.
- the reclosing elements are strongly bent at the folding or folding edges of the film bag.
- the reclosing strip for a zipper closure has considerable elastic restoring forces, which counteract the kinking and can result in the flat-lying foil bag spreading in the area of the first gusset. With increasing stack height then there is a risk that the stacked bags slip.
- the strip-shaped closure elements of the reclosable strip can be interrupted at the bent edges of the film bag by a punched or cut.
- the closure strip is after being applied to a first still flat film web, at the point at which later the bending edge of the gusset is or the film web is folded, punched or cut.
- a preferred embodiment of the invention provides that the length of the reclosure strip is greater than the width of the first gusset, with a central portion of the reclosure strip is attached to the inner surface of the gusset and wherein on both sides subsequent end portions of the reclosure strip are connected to the inside of the front surface and the rear surface of the bag.
- the reclosable strip can be designed as a Velcro strip, as a strip with a self-adhesive surface or as a zipper closure, whose positive-locking elements can be connected to themselves.
- the reclosing strip fastened to the inner surface of the first gusset has a length corresponding to the width of the gusset and extends to the outer edges of the bag and closure strips are secured to the inner surfaces of the front surface and the back surface. which cooperate with the reclosable strip attached to the first gusset.
- Suitable profiles for the reclosure strips and closure strips are in DE 201 15 181 U1 described.
- all four outer edges of the film bag are stiffened by longitudinal sealing seams.
- the longitudinal sealing seam closing the foil bag on the shell side can be integrated into an edge which bounds the second side fold.
- the longitudinal seam seam closing the foil bag on the shell side connects the second side fold with the front or back surface of the bag.
- the front and back surfaces of the bag may be joined by a vertical additional seam which is disposed adjacent the first gusset and extends from a transverse seam adjacent the reclosure strip to the top seal and separates the gusset portion above the reclosure from the fill space of the bag.
- the transverse sealing seam which closes the filling material space on the upper side, runs parallel to the top-seal seam. However, it is also within the scope of the invention to align this transverse sealing seam at an angle to the top seal seam, the distance between the transverse seal seam and the top seal at the first end adjacent the vertical auxiliary seam is smaller than at the other end in the region of the second side fold.
- the section of the film bag which is delimited by the top seal seam and the transverse seal seam can also be used for a handle punching.
- the film bag shown in the figures is formed by folding a film and has a front face 1, a rear face 2, an inserted first side fold 3 and an inserted second side fold 4.
- the film bag is closed by a longitudinal sealing seam 5, a top seal seam 6 and a bottom seam seam, not shown.
- a reclosure strip 7 is fixed, which releasably removes the first side gusset 3 with the adjacent front surface and back surface of the gusset Bag connects.
- a bag section 8 must be torn open above the reclosing strip 7 along a weakening line 9 contained in the film. Thereafter, the first gusset 3 forms a resealable chute.
- the longitudinal sealing seams 10 extend from a bottom seam, not shown, to the top seam 6 and are interrupted in the region of the reclosing strip 7.
- the second gusset 4 is limited by outer edges, which are reinforced by longitudinal sealing seams.
- the cross-sectional view in Fig. 3 one takes that the film bag closing the shell side longitudinal sealing seam 5 is moved into the outer edge of the second side fold into and connects the second side fold 4 with the front or back surface 1, 2 of the bag.
- the longitudinal sealing seam 5 fulfills a sealing function, while the sealing seams assigned to the other outer edges only reinforce folding edges and have no sealing function.
- the reclosure strip 7 has a film carrier 11 which can be fastened to the inner surface of the bag and strip-shaped closure elements 12 integrally formed on the film carrier.
- the strip-shaped closure elements 12 form a zipper closure of form-fitting elements, which can be latched together manually by pressure.
- the strip-shaped closure elements 12 may be interrupted by a punched or cut. This measure prevents a spreading of the gusset area as a result of a bending stress of the strip-shaped projections of the closure elements.
- the length of the reclosure strip 7 is greater than the width of the first gusset 3, with a central portion of the reclosure strip secured to the inner surface of the gusset and having adjoining thereon on both sides End portions of the WiederverschlußstMails 7 are connected to the inner surfaces of the front surface 1 and the rear surface 2 of the bag.
- the closure elements 12 of the reclosure strip 7 are formed so that they can be connected to themselves.

Ein Folienbeutel mit dem beschriebenen Aufbau eignet sich zur Verpackung von Schüttgut, beispielsweise Trockenfutter für Tiere, und weist einen Wiederverschluss auf, der es erlaubt, den Inhalt der Verpackung in Teilmengen, also portionsweise auszuschütten bzw. zu entnehmen. Die Entnahme erfolgt durch eine Öffnung in der ersten Seitenfalte, wobei die Seitenfalte nach Öffnen des Wiederverschlusses herausziehbar ist und als Schütte genutzt werden kann. Die Öffnung ist wiederverschließbar. Der Wiederverschluss kann als so genannter Zipperverschluss ausgeführt werden, der leistenförmige Nut- und Federelemente aufweist, die manuell durch Druck miteinander verbunden werden können und dann eine Rast- bzw. Clipsverbindung bilden. Auch andere Wiederverschlüsse, z. B. Klettverschlüsse oder Wiederverschlüsse mit einem selbstklebenden Streifen, sind denkbar.A film bag with the described structure is suitable for the packaging of bulk material, such as dry food for animals, and has a reclosure, which allows the contents of the package in portions, ie pour out in portions or remove.

Ein Folienbeutel mit den eingangs beschriebenen Merkmalen ist aus
Aus
Ein ähnlicher Folienbeutel wie die zuvor beschriebenen Ausführungen mit einer wiederverschließbaren Entnahmeöffnung in der Seitenfalte ist aus
Wiederverschließbare Folienbeutel, die beispielsweise zur Verpackung von Trockenfutter für Tiere verwendet werden, bestehen in der Praxis aus hochwertigen Verbundfolien, die eine gut bedruckbare Außenschicht aus Polyester, eine siegelbare Innenschicht aus einem Polyolefin und häufig eine metallische Zwischenschicht mit einer guten Barrierewirkung in Bezug auf Sauerstoff und Wasserdampf aufweisen. Problematisch ist die Schwächungslinie. Sie ist bei den bekannten Folienbeuteln häufig als Perforation ausgebildet, welche luftdurchlässig ist. Der im Innern des Folienbeutels angeordnete Wiederverschluss stellt ebenfalls keinen gasdichten Verschluss dar, so dass das Füllgut bei einer längeren Lagerung austrocknen kann und sich die Produkteigenschaften des Füllgutes verändern können.Resealable foil pouches, which are used, for example, for packaging animal dry food, in practice consist of high quality composite films comprising a readily printable polyester outer layer, a sealable polyolefin innerliner, and often a metallic one Intermediate layer with a good barrier effect with respect to oxygen and water vapor. The problem is the weakening line. It is often formed in the known foil bags as a perforation, which is permeable to air. The reclosure, which is arranged in the interior of the film bag, likewise does not constitute a gas-tight closure, so that the contents can dry out during prolonged storage and the product properties of the contents can change.
Ein wiederverschließbarer Folienbeutel mit den Merkmalen des Oberbegriffs des Patentanspruchs 1 ist aus der älteren, jedoch nicht vorveröffentlichten
Vor dem erläuterten technologischen Hintergrund liegt der Erfindung die Aufgabe zugrunde, die Gebrauchseigenschaften von Folienbeuteln zu verbessern. Der Folienbeutel soll sich insbesondere leicht öffnen lassen und bei der Entnahme von Füllgut gut handhabbar sein.Before the explained technological background, the invention has the object to improve the performance of plastic bags. The film bag should be particularly easy to open and be easy to handle when removing contents.
Die Aufgabe wird erfindungsgemäß durch einen Folienbeutel mit den Merkmalen des Anspruches 1 gelöst.The object is achieved by a film bag with the features of
Die Schwächungslinie besteht aus einer durch Heißsiegeln erzeugten Prägelinie und einer deckungsgleich ausgeführten Lasernaht. Durch das Heißsiegeln wird die Folie unter der Einwirkung von Druck und Temperatur verformt, und im Laserverfahren erfolgt im Bereich der Prägelinie ein partieller Materialabtrag an der Außenseite der Verbundfolie. Die erfindungsgemäße Kombination einer Lasernaht mit einer heißgesiegelten Prägelinie ergibt eine Schwächungslinie, die sich durch ein sehr gutes Aufreißverhalten auszeichnet. Das Aufreißen ist leichtgängig und erfolgt mit einer definierten Ausbreitung entlang der Schwächungslinie. Dadurch, dass der Laserabtrag auf die Außenschicht der Verbundfolie beschränkt ist, bleibt die Schwächungslinie luftdicht. Die Permeation von Sauerstoff und Wasserdampf durch den Bereich der Schwächungslinie ist vernachlässigbar. Dort, wo die Schwächungslinie die durch Längssiegelnähte verstärkten Faltkanten erreicht, sind Kerben in den Längssiegelnähten zur Rissinitiierung vorgesehen.The weakening line consists of an embossing line produced by heat-sealing and a laser seam of congruent design. By heat sealing, the film is deformed under the action of pressure and temperature, and in the laser process takes place in the region of the embossing line, a partial removal of material on the outside of the composite film. The inventive combination of a laser seam with a heat-sealed embossing line results in a line of weakness, which is characterized by a very good tear behavior. The tearing is smooth and takes place with a defined propagation along the weakening line. Because of the laser ablation on the outer layer of the Composite film is limited, the weakening line remains airtight. The permeation of oxygen and water vapor through the area of the line of weakness is negligible. Where the line of weakness reaches the folding edges reinforced by longitudinal sealing seams, notches are provided in the longitudinal sealing seams for crack initiation.
Die Schwächungslinie kann sich parallel zu dem Wiederverschlussstreifen und einer daran anschließenden Quersiegelnaht, welche den Füllgutraum oberseitig schließt, über die gesamte Breite des Folienbeutels bis zu den Rändern der zweiten Seitenfalte erstrecken. Im Rahmen der Erfindung liegt es aber auch, dass die Schwächungslinie sich parallel zu dem Wiederverschlussstreifen erstreckt und dann mit einem vertikalen Abschnitt zur Kopfsiegelnaht ausläuft.The weakening line can extend parallel to the reclosing strip and an adjoining transverse seam, which closes the filling material space on the upper side, over the entire width of the film bag up to the edges of the second side fold. In the context of the invention, however, it is also the case that the weakening line extends parallel to the reclosing strip and then ends with a vertical section towards the top-seal seam.
Durch das Aufreißen eines Beutelabschnittes entlang der Schwächungslinie wird der Wiederverschluss in der ersten Seitenfalte des Folienbeutels freigelegt. Nach Freilegen des Wiederverschlusses kann die Seitenfalte als Schütte ausgeklappt werden, wobei sich eine Schüttöffnung ergibt, die zumindest doppelt so lang ist wie die Breite der Seitenfalte. Die große Öffnung erleichtert die Entnahme von stückigem Füllgut. Die zur Kantenversteifung vorgesehenen Längssiegelnähte verleihen dem Folienbeutel auch in geöffnetem Zustand eine beachtliche Formstabilität, so dass auch eine gute Handhabe von großen Folienbeuteln gewährleistet ist. Die zur Kantenversteifung vorgesehenen Längssiegelnähte können im Bereich des Wederverschlussstreifens ausgespart werden. Auf die Dichtigkeit des Folienbeutels hat dies keinen Einfluss, da die Außenkante der ersten Seitenfalte Faltkanten sind und die zusätzlich angebrachten Längssiegelnähte keine Dichtungsfunktion besitzen.By tearing a bag section along the line of weakness, the reclosure in the first gusset of the foil bag is exposed. After exposing the reclosure, the gusset can be unfolded as a chute, resulting in a pouring opening, which is at least twice as long as the width of the gusset. The large opening facilitates the removal of lumpy contents. The provided for edge reinforcement longitudinal sealing seams give the film bag in the open state a considerable dimensional stability, so that a good handle of large plastic bags is guaranteed. The longitudinal sealing seams provided for edge reinforcement can be recessed in the area of the self-locking strip. On the tightness of the film bag, this has no effect, since the outer edge of the first side fold folding edges and additionally attached longitudinal sealing seams have no sealing function.
Der Wiederverschlussstreifen bildet vorzugsweise einen Zipperverschluss und weist einen an der Innenfläche des Beutels befestigbaren Folienträger und an den Folienträger angeformte leistenförmige Verschlusselemente auf. Die leistenförmigen Verschlusselemente sind nach Art einer Nut- und Federverbindung durch Druck manuell miteinander verrastbar. Der Folienträger ist zweckmäßig mit zwei Siegelnähten, die beidseits der leistenförmigen Verschlusselemente angeordnet sind, mit der den Folienbeutel bildenden Folie verbunden.The reclosure strip preferably forms a zipper closure and has a film carrier attachable to the inner surface of the bag the strip carrier molded strip-shaped closure elements. The strip-shaped closure elements are manually latched together by pressure in the manner of a tongue and groove connection. The film carrier is expediently connected with two sealing seams, which are arranged on both sides of the strip-shaped closure elements, with the film forming the film bag.
Die Folienbeutel werden als flachgelegte Beutel gefertigt und erst später in Abfüllanlagen mit Füllgut befüllt, welches beispielsweise durch eine bodenseitige Öffnung oder - vor Anbringung der Kopfsiegelnähte - am oberen Ende des Beutels eingefüllt wird. Für den Transport werden die flach liegenden Folienbeutel gestapelt. Dabei werden die Wiederverschlusselemente an Falt- bzw. Knickkanten des Folienbeutels stark gebogen. Der Wiederverschlussstreifen für einen Zipperverschluss besitzt erhebliche elastische Rückstellkräfte, die dem Knicken entgegenwirken und zur Folge haben können, dass die flachliegenden Folienbeutel im Bereich der ersten Seitenfalte aufspreizen. Bei zunehmender Stapelhöhe besteht dann die Gefahr, dass die aufeinander gestapelten Beutel verrutschen. Um dies zu vermeiden, können die leistenförmigen Verschlusselemente des Wiederverschlussstreifens an Knickkanten des Folienbeutels durch eine Ausstanzung oder einen Schnitt unterbrochen werden. Bei der Fertigung des Folienbeutels wird der Verschlussstreifen nach dem Aufbringen auf eine zunächst noch ebene Folienbahn, an der Stelle, an der später die Knickkante der Seitenfalte ist bzw. die Folienbahn gefaltet wird, eingestanzt oder eingeschnitten.The foil pouches are manufactured as flat-laid pouches and filled with filling material later in filling systems, which is filled at the upper end of the pouch, for example, by a bottom-side opening or, before attachment of the head sealing seams. For transport, the flat foil bags are stacked. The reclosing elements are strongly bent at the folding or folding edges of the film bag. The reclosing strip for a zipper closure has considerable elastic restoring forces, which counteract the kinking and can result in the flat-lying foil bag spreading in the area of the first gusset. With increasing stack height then there is a risk that the stacked bags slip. To avoid this, the strip-shaped closure elements of the reclosable strip can be interrupted at the bent edges of the film bag by a punched or cut. In the manufacture of the film bag, the closure strip is after being applied to a first still flat film web, at the point at which later the bending edge of the gusset is or the film web is folded, punched or cut.
Hinsichtlich des Anbringens des Wiederverschlussstreifens ergeben sich mehrere Möglichkeiten. Eine bevorzugte Ausführung der Erfindung sieht vor, dass die Länge des Wiederverschlussstreifens größer ist als die Breite der ersten Seitenfalte, wobei ein mittlerer Abschnitt des Wiederverschlussstreifens an der Innenfläche der Seitenfalte befestigt ist und wobei daran beidseitig anschließende Endabschnitte des Wiederverschlussstreifens mit der Innenseite der Frontfläche bzw. der Rückfläche des Beutels verbunden sind. Der Wiederverschlussstreifen kann als Klettstreifen, als Streifen mit einer selbstklebenden Oberfläche oder als Zipperverschluss, dessen Formschlusselemente mit sich selbst verbindbar sind, ausgebildet sein. Im Rahmen der Erfindung liegt es aber auch, dass der an der Innenfläche der ersten Seitenfalte befestigte Wiederverschlussstreifen eine der Breite der Seitenfalte entsprechende Länge aufweist und sich bis zu den Außenkanten des Beutels erstreckt und dass an den Innenseiten der Frontfläche und der Rückfläche Verschlussstreifen befestigt sind, die mit dem an der ersten Seitenfalte angebrachten Wiederverschlussstreifen zusammenwirken. Geeignete Profile für die Wiederverschlussstreifen und Verschlussstreifen sind in
Gemäß einer vorteilhaften Ausgestaltung der Erfindung sind alle vier Außenkanten des Folienbeutels durch Längssiegelnähte versteift. Die den Folienbeutel mantelseitig schließende Längssiegelnaht kann in eine Kante, welche die zweite Seitenfalte begrenzt, integriert werden. Bei dieser Ausführung verbindet die den Folienbeutel mantelseitig schließende Längssiegelnaht die zweite Seitenfalte mit der Front- oder Rückfläche des Beutels.According to an advantageous embodiment of the invention, all four outer edges of the film bag are stiffened by longitudinal sealing seams. The longitudinal sealing seam closing the foil bag on the shell side can be integrated into an edge which bounds the second side fold. In this embodiment, the longitudinal seam seam closing the foil bag on the shell side connects the second side fold with the front or back surface of the bag.
Die Front- und Rückflächen des Beutels können durch eine vertikale Zusatznaht verbunden werden, die neben der ersten Seitenfalte angeordnet ist und sich von einer an den Wiederverschlussstreifen anschließenden Quersiegelnaht bis zur Kopfsiegelnaht erstreckt und den Seitenfaltenbereich oberhalb des Wiederverschlusses von dem Füllgutraum des Beutels trennt. Die Quersiegelnaht, die den Füllgutraum oberseitig schließt, verläuft parallel zur Kopfsiegelnaht. Im Rahmen der Erfindung liegt es aber auch, diese Quersiegelnaht schräg zur Kopfsiegelnaht auszurichten, wobei der Abstand zwischen der Quersiegelnaht und der Kopfsiegelnaht am ersten Ende, das an die vertikale Zusatzsiegelnaht angrenzt, kleiner ist als an dem anderen Ende im Bereich der zweiten Seitenfalte. Der von der Kopfsiegelnaht und der Quersiegelnaht begrenzte Abschnitt des Folienbeutels kann ferner für eine Handgriffausstanzung genutzt werden.The front and back surfaces of the bag may be joined by a vertical additional seam which is disposed adjacent the first gusset and extends from a transverse seam adjacent the reclosure strip to the top seal and separates the gusset portion above the reclosure from the fill space of the bag. The transverse sealing seam, which closes the filling material space on the upper side, runs parallel to the top-seal seam. However, it is also within the scope of the invention to align this transverse sealing seam at an angle to the top seal seam, the distance between the transverse seal seam and the top seal at the first end adjacent the vertical auxiliary seam is smaller than at the other end in the region of the second side fold. The section of the film bag which is delimited by the top seal seam and the transverse seal seam can also be used for a handle punching.

Der in den Figuren dargestellte Folienbeutel ist durch Falten einer Folie geformt und weist eine Frontfläche 1, eine Rückfläche 2, eine eingelegte ersten Seitenfalte 3 sowie eine eingelegte zweite Seitenfalte 4 auf. Der Folienbeutel ist durch eine Längssiegelnaht 5, eine Kopfsiegelnaht 6 und eine nicht dargestellte Bodensiegelnaht verschlossen. An der Innenfläche des Folienbeutels unterhalb der Kopfsiegelnaht 6 ist ein Wiederverschlussstreifen 7 befestigt, der die erste Seitenfalte 3 lösbar mit der benachbarten Frontfläche und Rückfläche des Beutels verbindet. Zur Füllgutentnahme muss ein Beutelabschnitt 8 oberhalb des Wiederverschlussstreifens 7 entlang einer in der Folie enthaltenen Schwächungslinie 9 aufgerissen werden. Danach bildet die erste Seitenfalte 3 eine wiederverschließbare Schütte. Aus einer vergleichenden Betrachtung derFig. 1 bis 3 wird deutlich, dass die Faltkanten zwischen der ersten Seitenfalte 3 und der angrenzenden Front- bzw. Rückfläche 1, 2 durch Längssiegelnähte 10 versteift sind. Die Längssiegelnähte 10 erstrecken sich von einer nicht dargestellten Bodensiegelnaht bis zur Kopfsiegelnaht 6 und sind im Bereich des Wiederverschlussstreifens 7 unterbrochen.

An der Knickkante 13 der eingelegten Seitenfalte 3 können die leistenförmigen Verschlusselemente 12 durch eine Ausstanzung oder einen Schnitt unterbrochen sein. Diese Maßnahme verhindert ein Aufspreizen des Seitenfaltenbereiches in Folge einer Biegebeanspruchung der leistenförmigen Vorsprünge der Verschlusselemente. Die Länge des Wiederverschlussstreifens 7 ist größer als die Breite der ersten Seitenfalte 3, wobei ein mittlerer Abschnitt des Wiederverschlussstreifens an der Innenfläche der Seitenfalte befestigt ist und wobei daran beidseitig anschließende Endabschnitte des Wiederverschlussstreifens 7 mit den Innenflächen der Frontfläche 1 bzw. der Rückfläche 2 des Beutels verbunden sind.
