DESCRIPTION

Plastic shipping bag, in particular for sale by online mail.

Description

The present invention relates to a plastic shipping bag, in particular an online plastic shipping bag. The invention further relates to the use of a plastic shipping bag of this type for the transport of shipped products, in particular products shipped from online commerce.

Conventional plastic shipping bags are sufficiently known by the prior art. WO 91/15406 A1 describes, for example, a security bag that has, on its rear side, a flange with an adhesive means for closing the security bag.

The publication of application 2 601 582 refers to a process for the manufacture of block bags with central bottom opening. The central bottom opening is used in bags for vacuum cleaners.

Document DE 1 170 861 refers to a sack or bag made of paper with a cross or folded bottom, finishing the overlapping parts of the bottom flanges laterally in open flanges. These make an opening of the bottom of the bag possible.

Document DE 1 882 441 U1 refers to a packaging for consumer goods that is formed as a shopping bag. At the same time the upper side is closed while the lower side is open ("lacks bottom"). Coating parts can be used to close the bottom side after the introduction of the products.

In US2007 / 0062161 another example of a plastic bag that can be resealed with a bottom fold is shown. Plastic shipping bags are used regularly in online mail commerce. Here it does not happen rarely that the requested product must be returned, for various reasons, for example due to complaints of deficiencies. To make possible a simple and economical management of returns must be reused and the same bags of a customer with which the product was sent are frequently reused. For a safe return expedition, the customer must close the bag for the

transport back, after a single opening and removal of the product, after introducing it again. The

opening of such bags by a customer should take place, if possible, in such a way that a closing again after the bag is admissible without further ado. Advantageously, use is made of plastic shipping bags of this type which, after the first closure, can be opened without problems without additional auxiliary means. Similarly, plastic bags must be able to be closed again for a return shipment, in a reliable and non-problematic way, so that during transport the product is present in

safe way in the shipping bag, and this in particular without having to make use again for closing

of additional auxiliary means. Numerous closure systems for bag openings of plastic shipping bags of this type are known from the prior art. The attention was paid to the conception of suitable plastic shipping bags, obviously, in the opening of the bag.

Until now the product is removed from the plastic shipping bag, returned in this way and way to the merchant or manufacturer, with the destruction of the plastic shipping bag. The foil strips used for plastic shipping bags of this type are increasingly resistant, they are especially more resistant to breakage, and this although the foil systems used are, at the same time, increasingly thin. It is also possible to provide, with the adhesive materials used, a very strong connection between the plastic sheet band that closes the opening and the adjacent plastic material. On a few occasions, a very large force application is required to tear the sheet closure or the sheet material. Alternatively or additionally, the use of knives or scissors is used, in order to get back the product sent back. In this case, this also certainly damages the returned goods. Therefore, it would be desirable to be able to resort to plastic shipping bags that do not suffer from the deficiencies described.

Therefore, the present invention raised the problem of providing plastic shipping bags that allow, in a simple and reliable way, to be able to withdraw products sent or returned from plastic shipping bags, without running the risk of damaging the product.

The problem posed by the present invention is solved by means of a plastic shipping bag, which comprises a front wall of the bag and a rear wall of the opposite bag, respectively with upper edges, lower edges as well as a first and a second side edges, a particular opening of the bag that can be closed, an opposite bottom of the bag with a bottom fold and a first bottom fold section extending from the bottom edge of the front wall of the bag to the bottom fold, and a second bottom fold section that extends from the bottom edge of the back wall of the bag to the bottom fold, the front wall of the bag being and the back wall of the bag

connected to each other, in particular welded, along or adjacent to their respective first and second lateral edges, configuring first or second elongated connection zones, in particular first and second connecting strips or lines, extending from the transition from the first folding section of the bag to the front wall of the bag, in particular from the bottom edge of the front wall of the bag, and from the transition from the second folding section of the bag to the rear wall of the bag bag, in particular from the bottom edge of the rear wall of the bag, at least a first, second, third and fourth area of weakening, particularly elongated, in particular at least a first, second, third and fourth perforation line , at least sectionally adjacent and distanced from the first elongated connection area in the direction of the opening of the bag in the front wall it was of the bag and the back wall of the bag as well as the first and second bottom folding sections and extending at least one other area of elongated weakening, in particular another perforation line, from the first, second, third and / or fourth area of weakening, particularly elongated, preferably essentially orthogonal, in the direction of the second elongated connection area.

The present invention is accompanied by the surprising knowledge that plastic shipping bags that can be opened in a relatively simple manner can be obtained without, however, having to accept losses in terms of sealing the contents and opening the packaging. It has been surprisingly shown that the first, second, third and fourth area of weakening make it possible, in this case, an especially simple opening, by not entering the product sent in contact with sharp objects or being subjected to excessive pressure. The weakening areas, which are arranged in the manner described above, allow, however, to seal products sent in plastic shipping bags during transport, despite the fact that the bottom of the bag is loaded according to the invention during transport.

A plastic shipping bag within the meaning of the present invention is a bag intended for the transport of products, in particular products of online commerce. A shipping bag of this type can be closed in the usual manner preferably so that no opening remains unclosed. The plastic shipping bag usually has at least one area, in particular an interior space, for the accommodation of shipping products and items, which can be closed essentially completely and which is limited by the front wall of the bag, the back wall of the bag as well as the bottom of the bag. Bags that have bag openings that cannot be closed, which allow an unintended drop in shipping items during transport, are not generally suitable as shipping bags. It is fundamentally imaginable to deform a plastic shipping bag in such a way that a precise description of the geometry is no longer possible. For the remaining embodiments, it is assumed that the description refers to an unfilled, non-deformed state of the plastic shipping bag, the plastic shipping bag should preferably be contemplated in essentially flat. In this way, the shipping bag is usually provided before filling with shipping items.

In the plastic shipping bag according to the invention it is advantageous that it extends, from the transition from the first bag folding section to the front wall of the bag, in particular from the bottom edge of the front wall of the bag , and from the transition of the second bag folding section to the rear wall of the bag, in particular from the bottom edge of the rear wall of the bag, at least a fifth, sixth, seventh and eighth area of weakening , in particular elongated, in particular at least a fifth, sixth, seventh and eighth adjacent and distant perforation line with respect to the second elongated connection area in the direction of the opening of the bag on the front wall of the bag and in the back wall of the bag as well as the first and second bottom folding sections. This makes possible an opening on both sides of the plastic shipping bag without the bag having to be turned around in its case, in order to obtain a corner with perforation lines.

In addition, it is provided in suitable configurations according to the invention that the at least one other area of elongated weakening, which extends from the first, second, third and / or fourth area of weakening in the direction of the second elongated connection area, comprises or represents at least a ninth elongated weakening area, in particular ninth perforation line, which extends from the first and / or second weakening area, in particular elongated, in the direction of the second elongated connection area, in particular at least to the fifth and / or sixth area of weakening, in the transition from the front wall of the bag to the first folding section of the bottom, in particular parallel to the bottom edge of the front wall of the bag and / or comprises or represented by at least an eleventh area of elongated weakening, in particular eleventh drilling line that extends from the third and / or fourth area of d stabilization, in particular elongated, in the direction of the second area of elongated weakening, in particular at least until the seventh and / or eighth area of weakening in the transition from the back wall of the bag to the first section of bottom folding, in particular parallel to the bottom edge of the rear wall of the bag.

In especially preferred configurations it is provided that the at least one other area of elongated weakening that extends from the first, second, third and / or fourth area of weakening in the direction of the second elongated connection area, comprises or represents at least one tenth area of elongated weakening, in particular at least one tenth perforation line, which or which extend from the second area of weakening, particularly elongated, in the direction of the second elongated connection area, in

particular at least up to the sixth area of weakening, in the first section of folding of the bottom, and / or at least one twelfth area of elongated weakening, in particular twelfth perforation line, which extends from the third area of weakening, in particular elongated, in the direction of the second elongated connection area, in particular at least until the seventh area of weakening, in the second section of bottom folding.

In a very particularly preferred configuration, the plastic delivery bag comprises about tenth and twelfth areas of opposite weakening. Here it is preferred that these are preferably arranged parallel to the bottom folding, the average distance to the bottom folding being preferably less than 5 cm, in particular 3 cm, especially preferably less than 2 cm.

In other particularly suitable configurations it is provided that at least one other area of elongated weakening extending from the first, second, third and / or fourth area of weakening in the direction of the second area of elongated weakening, comprises or represents at least one twentieth area of weakening, in particular a twentieth perforation line, which extend, along the bottom folding, from the second and / or third area of weakening, particularly elongated, in the direction of the second elongated connection area , in particular at least until the sixth and / or seventh area of weakening.

In an equally suitable embodiment, it is provided that at least one other area of elongated weakening extending from the first, second, third and / or fourth area of weakening, in the direction of the second elongated connection area, comprises at least a twenty-first and / or twenty-second weakening area, in particular a twenty-first and / or twenty-second perforation line, the twenty-first weakening area being arranged on the front side of the adjacent bag and distanced from the lower edge of the front side of the bag and the twenty-second weakening area is arranged on the back side of the adjacent bag and distanced from the bottom edge of the back side of the bag.

In a suitable configuration the second area of elongated weakening extends, in particular the first, second, third and fourth area of elongated weakening, in the direction of the opening of the bag also beyond the point from which the tenth area of elongated weakening extends in the direction of the second elongated connection area.

In another suitable configuration the third area of elongated weakening extends, in particular the first, second, third and fourth area of elongated weakening, also beyond point towards the opening of the bag, from which the twelfth area extends of elongated weakening in the direction of the second elongated connection area.

In another suitable configuration the sixth area of elongated weakening extends, in particular the fifth, sixth, seventh and eighth area of elongated weakening, also beyond the point in the direction of the opening of the bag, into which the tenth area of elongated weakening starting from the second lateral edge or the first connection area, in particular opposite.

In another suitable configuration the seventh elongated weakening area extends, in particular the fifth, sixth, seventh and eighth elongated weakening area also beyond the point in the direction of the opening of the bag, into which the twelfth weakening area ends. elongated from the third side edge or the first connection area, in particular opposite.

The plastic delivery bags according to the invention preferably have, in the area of the bottom of the bag, a W-shaped fold in cross section, this describing the type of arrangement of folding edges and not the angle between the edges of creased. The different W-shaped folding surfaces are preferably in contact with each other in the folded state. The W-shaped folding is preferably formed by the front wall of the bag and the back wall of the bag as well as the wall at the bottom of the bag.

Furthermore, it is preferred that the plastic shipping bag preferably has a length that is calculated according to the average distance between the upper edge and the lower edge of the rear side of the bag. In addition to preferring that the first, second, third, fourth and, eventually, fifth, sixth, seventh, eighth area of weakening are only in the lower third of the plastic shipping bag and / or that the maximum extension towards the bottom from the bag to the opening of the bag of the first, second, third, fourth and, eventually, fifth, sixth, seventh, eighth area of weakening corresponds to a maximum of 20%, in particular a maximum of 15%, preferably a maximum 12% of the length of the plastic shipping bag.

It is also particularly preferred that the first, second, third, fourth area of weakening be sectionally curved and preferably leads to the first lateral edge and / or the first connection area.

The plastic delivery bag also has a width that preferably corresponds to the average distance between the first and the second side edge of the rear wall of the bag. The width of the front wall of the bag is preferably less than the length of the front wall of the bag and the width of the rear wall of the bag is less than the length of the rear wall of the bag. This has the advantage that the corresponding weakening areas are arranged in the shortest part of the shipping bag, which results in greater stability.

In a suitable configuration it is provided that the at least one area of additional elongated weakening that extends from the first, second, third and / or fourth area of weakening, in the direction of the elongated connection area, extends along the entire width of the plastic shipping bag.

It is especially advantageous, according to the present teaching of the invention in some preferred configurations, that the front wall of the bag and the rear wall of the bag, except for the first and fourth as well as, eventually, the fifth and eighth areas of weakening, not understand other areas of weakening more.

In some suitable configurations the first, second, third, fourth or, possibly, fifth, sixth, seventh, eighth areas of weakening are arranged, in particular at least by sections, essentially orthogonal with respect to the at least one area of weakening. additional elongate, extending from the first, second, third and / or fourth area of weakening in the direction of the second elongated connection area.

Essentially orthogonal means, in the sense of the present invention, that the two corresponding elements, in particular areas of weakening, do not diverge from each other more than 10 °, in particular not more than 5 °, preferably not more than 2 ° with respect to The ideal orthogonal orientation. Similarly, essentially parallel means that the corresponding elements, in particular areas of weakening, do not diverge from each other more than 10 °, in particular not more than 5 °, preferably not more than 2 ° with respect to the ideal parallel orientation. Oriented essentially in the same direction means that the divergence with respect to an orientation in the same direction is not greater than 30 °, preferably means oriented essentially in the same direction, as a rule, essentially parallel.

It is also preferred in other configurations that the first, second, third, fourth and, eventually, fifth, sixth, seventh, eighth areas of weakening are cut, in sections, with the at least one area of additional elongation, which extends from the first, second, third and / or fourth area of weakening in the direction of the second elongated connection area, in particular in the form of intersecting perforation lines.

It is also preferred that the bottom of the bag has at least two weakening areas, preferably essentially parallel, in particular at least two weakening areas with a mean distance with respect to the essentially identical bottom folding. An essentially identical distance exists when the distances do not diverge from each other more than 30%, in particular 15%, preferably 5%.

The bottom of the bag is preferably connected with the first and second elongated connection areas, in particular it is welded with the first and second welded seams. The use of the same connection or welded seam to connect the front wall of the bag and the back wall of the bag to hold the bottom of the bag considerably reduces the number of work steps during manufacturing and consequently results in , reduced manufacturing costs of the plastic shipping bag.

Another configuration provides a plastic shipping bag comprising a closing opening of the bag, a bottom of the opposite bag, a front wall of the bag and a rear wall of the opposite bag, respectively with upper edge, lower edge , a first and second side edges, being connected to each other, in particular welded, the front wall of the bag and the rear wall of the bag, along their respective first and second side edges or adjacent thereto, configuring first or second longitudinally oriented elongated connection areas, in particular first and second connecting strips or lines, the bottom of the bag comprising a bottom folding or a third cross-sectional area, transversely oriented, in particular a connection strip or a line of connection, preferably a welded seam or being formed by a bottom fold or a third elongated connection area, in part iculate a welded seam, extending from the bottom of the bag, in particular from the folding of the bottom or the third elongated connection area, adjacent and distanced from the first elongated connection area, in particular the first strip or connection line, a particularly elongated thirteenth area of weakening, in particular a thirteenth perforation line, on the front wall of the bag in the direction of the opening of the bag, in particular not protruding from the middle or lower third of the expedition bag plastic, and / or extending from the bottom of the bag, in particular from the folding of the bag or the third connection area, adjacent and distanced from the first elongated connection area, in particular from the first connection strip or line , a particularly elongated fourteenth area of weakening, in particular a fourteenth perforation line, on the rear wall of the bag in the direction of the opening of the bag, eventually extending from the bottom of the bag, in particular from

the folding of the bottom or of the third elongated, adjacent and spaced connection area with respect to the second elongated connection area, in particular the second connection strip or line, a fifteenth weakening area, particularly elongated, in particular fifteenth line of perforation, on the front wall of the bag in the direction of the opening of the bag, and / or possibly extending from the bottom of the bag, in particular from the folding of the bottom or of the third elongated connection area, adjacent and distanced with respect to the second elongated connection area, a sixteenth area of weakening, particularly elongated, in particular sixteenth perforation line, on the rear wall of the bag towards the opening of the bag, extending at least a seventeenth area of weakening, particularly elongated, in particular seventeenth perforation line, from the thirteenth area of weakening, in particular elongated, and / or the fourteenth area of weakening, in particular elongated, in the direction of the second elongated connection area, in particular at least until the fifteenth and / or sixteenth area of weakening, at the bottom of the bag or of the folding of the bottom, and / or extending in the front wall of the bag at least an eighteenth area of weakening, in particular elongated, in particular eighteenth perforation line, adjacent and distanced from the bottom of the bag, in particular with with respect to the folding of the bottom or the third elongated connection area, from the first weakening area, in particular elongated, in the direction of the second elongated connection area, in particular at least to the fifteenth weakening area, particularly elongated, and / or extending at the back wall of the bag at least a nineteenth area of weakening, particularly elongated, in particular nineteenth line ea of perforation, adjacent and spaced from the bottom of the bag, in particular with respect to the folding of the bottom or the third elongated connection area, from the fourteenth weakening area, particularly elongated, in the direction of the second connection area elongated, in particular at least until the sixteenth area of weakening, particularly elongated.

In the previous configuration which aims at a plastic delivery bag without folding the bottom it is advantageous that the thirteenth area of elongated weakening also extends beyond the point from which the eighteenth elongated area of weakening extends in the direction of the second elongated connection area, in the direction of the opening of the bag and / or that the fourteenth elongated weakening area also extends beyond the point, from which the nineteenth elongated weakening area extends in the direction of the second area of elongated connection, in the direction of the opening of the bag and when, eventually, the fifteenth area of elongated weakening also ends beyond the point at which the eighteenth area of elongated weakening ends, in the direction of the opening of the bag and / or when, eventually, the sixteenth area of elongated weakening also extends beyond the point, at which the nineteenth elongated weakening area ends, in the direction of the opening of the bag.

In addition, it is advantageous in the previous embodiment that the end of the lower bag has a V-shaped fold (also folded in V), this describing the type of folding arrangement and not the angle between the folding edges. The different surfaces of the V-fold are preferably located in the folded state, some in contact with each other. The V-shaped folding is preferably formed by the front wall of the bag and the rear wall of the bag as well as the wall at the bottom of the bag.

The following configurations refer to embodiments that, in harmony with all the above embodiments, refer to particularly preferred aspects.

For example, it is very especially preferred that the front wall of the bag and the rear wall of the bag as well as, eventually, the first and second bottom folding sections are based on a continuous section of a strip of continuous material, in particular of a continuous plastic sheet, the bottom of the bag being also an integral part of the indicated section of a strip of continuous material. It is therefore preferred that the front wall of the bag, the back wall of the bag and the bottom wall of the bag are integral parts of a section of a strip of continuous material, the front wall of the bag being delimited and the back wall of the bag by means of folds, in particular folds that are a part of the W-shaped fold, of the bottom of the bag, in particular of the first and second sections of the fold of the bag. This has the advantage that manufacturing can be greatly simplified and manufacturing costs can be reduced. In particular, no separate welded seam is often necessary to connect the front wall of the bag and the back wall of the bag and, eventually, the bottom of the bag at the bottom end of the bag. The different walls of the bag can be delimited with respect to each other by folding. In particular, the folding in W described above is suitable to delimit the bottom of the bag from the front wall of the bag and the back wall of the bag. This also has the advantage that the consumption of material during manufacturing is reduced. In addition, it has been shown that bends, unlike welded seams, are related to improved material cohesion.

It is also preferred that the front wall of the bag, the back wall of the bag and the bottom of the bag as well as, eventually, the first folding section of the bag and / or the second folding section of the bag comprise less a thermoplastic plastic, in particular a polyester and / or a polyolefin, preferably of at least one thermoplastic plastic, in particular a polyester and / or polyolefin.

Preferably at least one wall of the bag is used, in particular the front wall of the bag and / or the

rear wall of the bag and / or the bottom wall of the bag made of plastic, which is impervious to water and / or light. Light impermeable means, in this case, that the intensity of the light is significantly reduced by the wall of the corresponding bag, preferably at least 30%, in particular at least 50% and especially preferably at least 70% Water impermeability serves to protect the expedition item, in particular against weather-influenced influences such as rain, snow or air humidity. The reduction of light intensity also serves for protection, for example against UV discoloration, although it is also important to meet the requirements of postal secrecy.

In a particularly advantageous configuration of the plastic delivery bag according to the invention, the front wall of the bag has a first layer corresponding to the average distance between the upper edge and the lower edge of the front wall of the bag and the rear wall of the bag a second length, which corresponds to the average distance between the upper edge and the lower edge of the rear wall of the bag, the first length being shorter than the second length, so that the rear wall of the bag protrudes , by the upper end of the bag, of the front wall of the bag and this section protruding from the front wall of the bag can be folded onto the front wall of the bag. The part of the back wall of the bag that protrudes from the front wall of the bag can be folded in order to close the opening of the bag by the top end of the bag.

It is also preferred that the front or rear wall of the bag, in particular the section of the rear wall of the bag protruding from the front wall of the bag, present at the top end of the bag at least one fastening means, this section being designed, in particular after the folding of the indicated protruding section of the rear wall of the bag on the front wall of the bag, to close the opening of the bag at the upper end of the bag. The rear wall of the bag preferably has, in the upper edge of the rear wall of the bag or adjacent to it, some fastening means, these fastening means being designed, in particular after a folding of the rear wall of the bag on the front wall of the bag, to close the opening of the bag at the top end of the bag. Alternatively or additionally, the front wall of the bag may also have fastening means in order to close the opening of the bag. By folding the bag deforms only slightly so that, for example, the documents are not folded. In particular, an opening of the bag that uses a closure thread to narrow the opening of the bag to full closure would be completely unsuitable for documents. In another configuration, the at least one fastening means extends, at least a first adhesive strip which extends preferably from a first lateral edge to a second, opposite lateral edge.

Preferably, the first and / or second opening of the bag can be closed with at least one adhesive strip (first adhesive strip). This would extend, in the opening of the bag, preferably along the upper end of the bag, in particular along (and eventually at a distance) from the upper edge. Adhesive strips allow fast and secure sealing. In a preferred embodiment, the opening of the bag that can be closed by means of a fastener can be closed, preferably with at least one first adhesive strip, in particular irreversibly, preferably presenting the back wall of the bag, by the inner side, and / or the front wall of the bag, on the outer side, the indicated fastening means, in particular so that they come into contact with the front wall of the bag or with the back wall of the bag, if a section of the back wall of the bag is folded over the front wall of the bag. In one embodiment, the opening of the bag can be resealed by a second adhesive strip. Here the second adhesive strip is preferably arranged spaced, essentially parallel with respect to the second adhesive strip.

It is also preferred that the opening of the bag extends between the first wall edge and the second wall edge and is limited, preferably on the first or second side edge, by first or second elongated connection areas, in particular first and second strips or connection lines. In one configuration, the lateral edges are connected directly, in particular they are welded, configuring the connection areas. This is advantageous since in this way the accommodation area for shipping items is maximized. In an alternative embodiment, the first and second elongated connection areas do not coincide, in particular the first and second welded seams, with the first and second lateral edges, but are slightly spaced from them. In this case, it is preferred that the first connection area, in particular the first welded seam, runs at an average distance from the first side edges of the front wall of the bag and the back wall of the bag and that the Second connection area, in particular the second welded seam, runs a second middle distance with respect to the second side edges of the front wall of the bag and the rear wall of the bag. The first average distance and the second average distance are preferably equally large. It is further preferred that the first average distance and / or the second average distance be less than 3 cm, in particular less than 2 cm and, preferably, less than 1 cm. Welded seams, which are not directly at the side edges, often have greater stability. These welded seams are preferably thermoplastic welded seams.

It has been shown to be especially suitable for the plastic shipping bag to be characterized by

the upper edge of the front wall of the bag is present below the upper edge of the rear wall of the bag so that the rear wall of the bag forms a collapsible, protruding closure zone, and that the closure zone encompasses a first adhesive means, at least one second adhesive means and at least one weakening line, the first adhesive means being able to be separated or separated from the second by means of the at least one weakening line. The first and / or the at least second adhesive means and / or the at least one weakening line preferably run parallel to the edge of the opening side of the front side and / or the back side of the bag, being in particular the at least one weakening line farther from the edge of the opening side of the bag than the first adhesive means and the at least one additional adhesive means farther from the edge of the opening side than the at least one weakening line .

The first, second, third, fourth, fifth, sixth, seventh, eighth, ninth, tenth, eleventh and / or twelfth areas of weakening, in particular perforation lines, are preferably formed at the lower end of the bag. In addition it is preferred that all areas of weakening are formed at the lower end of the bag.

In some configurations it is also possible that the first or second elongated connection zones, in particular the first and second connection strips or lines, are oriented in the same direction, in particular they run essentially parallel or parallel to each other and / or that the first , second, third and fourth areas of weakening, particularly elongated, in particular the first, second, third and fourth perforation lines, run essentially in the same direction, preferably essentially parallel or parallel to each other and especially preferably covering each other and / or that the fifth, sixth, seventh and eighth areas of weakening, particularly elongated, in particular the fifth, sixth, seventh and eighth drilling lines, run essentially in the same direction, preferably essentially parallel or parallel to each other and of especially preferred way covering each other and / or why the tenth area of elongated weakening, in particular the tenth perforation line, and the twelfth area of elongated weakening, in particular the twelfth line of perforations, run essentially oriented in the same direction, preferably essentially parallel or parallel to each other and especially preferred covering each other.

In a suitable configuration the at least one line of weakening is at least for the most part and / or completely rectilinear, corrugated, punctured or zigzag-shaped.

In some particularly suitable embodiments, the transverse extension of the rear wall of the bag and / or the front wall of the bag is, measured from the first side edge to the second opposite side edge of the bag, greater than the longitudinal extension from the front wall of the bag and / or the back wall of the bag, measured from the bottom of the bag to the opening of the bag.

It has been shown as advantageous, in particular during transport, a carrying handle that has, in particular, a basic V-shaped or U-shaped shape, which is preferably formed square, rectangular, circular, semicircular or oval and, in particular , is disposed on the front wall of the bag and / or the back wall of the bag and / or is formed from them. Instead of or in addition to a carrying handle, at least one grip flange or at least one grip hole, which facilitate transport and grip, have also been shown to be suitable. According to the invention it is preferred that the lower end of the shipping bag present, in particular attached to the bottom of the shipping bag, adjacent or adjacent to it, at least one carrying handle.

This has the advantage that there is a carrying handle only where the end of the closed bag sufficiently reinforces the material of the bag.
