Description

[0001] The invention relates to a packaging sheet for a food, in particular for a snack, comprising a preferably rectangular, flexible sheet for wrapping the food.

[0002] The invention further relates to a packaging for a food product.

[0003] It is known from the state of the art to wrap food in packaging sheets for sale.

[0004] In particular, snacks are often wrapped or wrapped in aluminum foil for transport in accordance with the general state of the art.

[0005] For example, in one area of ​​butchery sales, it is known to wrap sausages in so-called wrapping paper.

[0006] Compared to wrapping paper, aluminum foil has the advantage that it is plastically deformable so that the snack can be safely and securely wrapped in the aluminum foil.

[0007] The disadvantage of the solutions known from the state of the art is that the use of aluminum foil is, on the one hand, environmentally harmful and expensive.

[0008] On the other hand, aluminum is suspected of being involved in the formation of harmful substances, particularly because it can react with acidic foods.

[0009] The present invention is based on the object of creating a packaging sheet which avoids the disadvantages of the prior art, in particular enabling stable packaging of foodstuffs.

[0010] According to the invention, this object is achieved by a packaging sheet having the features mentioned in claim 1.

[0011] The invention is further based on the object of creating a packaging for a food which avoids the disadvantages of the prior art, in particular enabling a safe transport of food.

[0012] According to the invention, this object is achieved by a packaging having the features mentioned in claim 14.

[0013] According to the invention, this object is also achieved by a packaging having the features mentioned in claim 15.

[0014] The packaging sheet according to the invention for a food product, in particular for a snack, comprises a preferably rectangular, flexible sheet for wrapping the food product. According to the invention, one or more adhesive areas are arranged on the sheet, which have an adhesive that adheres to the sheet.

[0015] The packaging sheet according to the invention has the advantage that, when the food is wrapped in the sheet, the at least one adhesive area can be brought into contact with the sheet itself to form an adhesive bond. This counteracts the tendency of the packaging sheet to unfold spontaneously, which is inherent in prior art solutions, and enables stable storage of the food.

[0016] Furthermore, in the packaging sheet according to the invention, the adhesive areas are arranged on the packaging sheet itself. This allows for the preparation and packaging of snacks at a high rate, as is often the case in snack bars.

[0017] Providing packaging sheets prepared with adhesive areas makes handling of the packaging sheet easier, as no separate adhesive strip needs to be removed.

[0018] Furthermore, this improves hygiene, as reaching around the snack when packaging can be advantageously avoided.

[0019] Preferably, the blade is rectangular. Alternatively, the blade can also have other shapes, in particular trapezoidal, triangular, circular, or oval.

[0020] In an advantageous development of the packaging sheet according to the invention, it can be provided that the sheet has a liquid-repellent coating on an inner side facing the food and / or the at least one adhesive area is arranged on the inner side.

[0021] If a liquid-repellent and / or liquid-impermeable coating is provided on the inner side facing the food, the packaging sheet is also suitable for wrapping foods that are typically consumed with sauces. These sauces or other food ingredients often contain acids, which can potentially form undesirable chemical bonds with the sheet material, and in the case of aluminum foil, potentially harmful.

[0022] This can be avoided by coating the sheet as described above.

[0023] The sheet may have a liquid-repellent and / or liquid-impermeable coating on the outer side facing away from the food. The sheet may also have a liquid-repellent and / or liquid-impermeable coating on the inner and outer sides.

[0024] It can be provided that the water-repellent coating is formed from or comprises a polymer and / or a wax, in particular a beeswax and / or a paraffin wax.

[0025] In particular, it may be stipulated that all components of the packaging sheet are food-safe.

[0026] It can be provided that the sheet as a whole is made of a liquid-repellent and / or liquid-impermeable material, for example a polymer film.

[0027] Since doner kebabs and durum kebabs are often sold with sauces, the coating described above is advantageous.

[0028] Furthermore, if the at least one adhesive area is arranged on the inside, the adhesive area can be located on an outside of the packaging sheet when the food is wrapped in the packaging sheet.

[0029] An adhesive bond is therefore preferably formed by applying pressure to an outer side of the packaging sheet opposite the adhesive area, wherein the adhesive area is in turn pressed onto a target area of ​​the outer side of the sheet lying beneath it.

[0030] In an advantageous development of the packaging sheet according to the invention, it can be provided that the at least one adhesive area is arranged in an area of ​​a corner of the sheet.

[0031] If the adhesive area is arranged in an area of ​​a corner of the sheet, wrapping can be achieved in a particularly efficient manner, since a maximum area of ​​the sheet can be used to wrap the food.

[0032] Furthermore, in order to increase and improve hygiene, it is particularly advantageous for a seller of the food to touch only one corner of the sheet.

[0033] If the sheet does not have a corner, it is advantageous if the at least one adhesive area is arranged on an edge area of ​​the sheet.

[0034] In an advantageous development of the packaging sheet according to the invention, it can be provided that two adhesive areas are each arranged in corners along a single side edge of the sheet.

[0035] If two adhesive areas are arranged at respective corners on individual side edges of the sheet, the stability and safety of holding the food can be further improved.

[0036] Furthermore, the flexibility of the packing person increases.

[0037] If the sheet has no corners, it is advantageous if the two adhesive areas are arranged at a distance from each other, preferably by at least one third of a diameter of the sheet, on an edge area of ​​the sheet.

[0038] It may be intended that the food is a snack in the form of a kebab.

[0039] In the case of a doner kebab, it is particularly advantageous to first fold an edge that is not provided with an adhesive area diagonally over the doner kebab, after which a corner opposite this corner, which has an adhesive area, is placed over the part of the sheet that has already been folded.

[0040] At this point, the packer can decide whether the first adhesive area needs to be used. If so, the first adhesive area is pressed onto the sheet at this point. In a second step, the remaining corner without the adhesive area is folded over the already folded sheet, and the second adhesive area is also folded over the sheet and glued to the sheet.

[0041] In the case of a snack in the form of a durum, it may be advantageous if the elongated durum is first rolled into the sheet along a diagonal of the sheet and then the first adhesive area is pressed onto the sheet to hold and secure the rolled-up sheet.

[0042] The person packing can then decide whether the roll produced in this way is to be closed at the top by folding in the corner provided with the second adhesive area or whether it is to be handed over to a customer open.

[0043] In an advantageous development of the packaging sheet according to the invention, it can be provided that a removable cover element is provided for covering the at least one adhesive area.

[0044] If the adhesive area is covered with a removable cover element, a large number of packaging sheets can be stored on top of each other in a stack. The risk of sticking is avoided by covering the adhesive areas.

[0045] This allows the packaging sheets to be easily removed individually from a pre-sorted and prepared stack. In particular, it is possible to place the food directly onto the stack and package it there, especially when prepared as a snack.

[0046] In an advantageous development of the packaging sheet according to the invention, it can be provided that the cover element projects beyond the sheet and / or the cover element only slightly covers the adhesive area and / or the cover element can be removed from the adhesive of the adhesive area without leaving any residue.

[0047] If the cover element protrudes beyond the sheet, it can be easily removed.

[0048] It is advantageous if the cover element completely covers the adhesive area, although the cover element should not be significantly larger than the adhesive area. This helps avoid waste.

[0049] It can be provided that the cover element is not significantly wider than the adhesive area in its width. In a longitudinal axis, the cover element is preferably designed to be large enough to protrude beyond the sheet, particularly for easy removal.

[0050] It is particularly advantageous if no adhesive adheres to the cover element after the cover element has been removed from the adhesive area and, in particular, the adhesive area is not damaged by the removal of the cover element or does not have a patchy distribution of the adhesive.

[0051] It can be provided that the cover element is made of wax paper.

[0052] In an advantageous development of the packaging sheet according to the invention, it can be provided that the adhesive is a beeswax and / or the sheet is made of wax paper.

[0053] If the adhesive is made of beeswax, the packaging sheet can be made in a particularly environmentally friendly way.

[0054] It may be provided that the sheet is made of waxed wrapping paper.

[0055] By avoiding aluminum foil, the environment can be protected and the risk of injury to customers from sharp foil edges can be avoided.

[0056] Furthermore, the aluminum foil known from the state of the art is very energy-intensive to produce. This packaging sheet therefore offers an energy-efficient, environmentally friendly, and cost-effective packaging option for food.

[0057] In an advantageous development of the packaging sheet according to the invention, it can be provided that it has an aspect ratio of 0.8 to 1.2, preferably of 1.0 and / or has edge lengths of 30 cm to 40 cm, preferably 35 cm.

[0058] The inventor has recognized that the aforementioned aspect ratios and edge lengths, particularly in combination with one another, are suitable for particularly advantageous packaging of commercially available doner kebabs or dürüm snacks.

[0059] In particular, one and the same cut of packaging sheet can be used to wrap both a doner kebab shop and a durum snack shop, which increases flexibility in the use of the packaging sheet.

[0060] In an advantageous development of the packaging sheet according to the invention, it can be provided that the adhesive is adhesive on an outer side of the sheet facing away from the food.

[0061] It is advantageous if, as described above, the adhesive connects a folded outer side of the sheet to the inner side on which the adhesive area is located.

[0062] For this purpose, it is advantageous if the adhesive also adheres to the outside of the sheet.

[0063] It is particularly advantageous if the adhesive adheres more strongly to the inside of the sheet than to the outside after establishing an adhesive bond when the food is wrapped in the sheet. This enables a reversible bond, or particularly easy and residue-free reopening of a package formed by the packaging sheet.

[0064] In an advantageous development of the packaging sheet according to the invention, it can be provided that - a pocket area is formed from a section of the sheet in such a way that two parallel longitudinal edges of the sheet are arranged lying on themselves and are connected to one another in an at least approximately liquid-tight manner, wherein - an opening area of ​​the pocket area is formed, and wherein - a remaining section of the sheet forms a cover area which can be folded over the opening area.

[0065] If the packaging sheet is designed as described above, the food can be inserted into the pocket area through the opening area of ​​the pocket area in a particularly simple manner.

[0066] Furthermore, the pocket area can be created in a particularly simple and highly efficient way by simply folding and gluing the sheet. This makes the packaging sheet suitable for large quantities, making it cost-effective and suitable for the snack food industry, as well as being environmentally friendly.

[0067] Because the lid area can be folded over the opening area and, like the pocket area, is formed from a single piece of the sheet, the packaging sheet can be closed particularly easily, even during fast-moving work processes such as those found in a snack bar.

[0068] In an advantageous development of the packaging sheet according to the invention, it can be provided that the at least one adhesive area is arranged on the lid area.

[0069] Because the adhesive area is located on the lid area and particularly on the inside of the sheet, the packaging sheet can be stored in stacks in a particularly simple manner before use.

[0070] Advantageously, the adhesive area is located on that part of the sheet which is to be moved in the further course of production of the packaging of the food to be packaged, since it is preferably provided that the lid area is folded over the opening area.

[0071] A target area for the adhesive area is then preferably located on the pocket area of ​​the sheet and there in particular on an outer side of the sheet facing away from the food.

[0072] In the above-described further development, a user of the packaging sheet according to the invention therefore does not have to pay attention to the exact positioning of the lid area on the relatively small adhesive area, since the adhesive area is already arranged on the lid area.

[0073] Alternatively or additionally, it may be provided that the adhesive area is arranged on the outside of the sheet at the pocket area of ​​the packaging sheet.

[0074] Such an arrangement, in turn, has the advantage that the adhesive area, and thus the adhesive, is only applied to the outer side of the sheet, away from the food. Contact between the adhesive and the food is thus eliminated.

[0075] In an advantageous development of the packaging sheet according to the invention, it can be provided that the sheet is rectangular and the adhesive area is arranged in the form of an adhesive strip along a transverse edge of the lid area perpendicular to the longitudinal edges

[0076] If the adhesive area in the form of an adhesive strip preferably extends over 50% to 100%, preferably 70% to 99%, particularly preferably 80% to 96%, of the transverse edge of the lid area, the packaging sheet can advantageously be closed completely by using the adhesive strip.

[0077] For cost-effective production with good holding power, the adhesive strip is preferably 0.5 cm to 2 cm wide, particularly preferably 1 cm wide.

[0078] It can be provided that further adhesive areas, in particular adhesive strips, are arranged along the sections of the longitudinal edges not involved in the formation of the pocket area.

[0079] Preferably, these also extend over at least 90% of the relevant sections of the longitudinal edges. By using all adhesive areas, the packaging sheet can advantageously be sealed at least approximately liquid-tight. This can prevent sauces from escaping from the packaging being formed.

[0080] In an advantageous development of the packaging sheet according to the invention, it can be provided that the sheet is rectangular and - 30% to 65%, preferably 40% to 58%, particularly preferably 48% or 54% of a length of the longitudinal edges contribute to the formation of the pocket area; and / or - an aspect ratio of a length of the longitudinal edge to a length of a transverse edge perpendicular to the longitudinal edge is 2 to 3, preferably 2.6; or 0.9 to 1.5, preferably 1.3; and / or - edge lengths of 15 cm to 40 cm, preferably 20 cm to 37 cm.

[0081] The inventor has recognized that the aforementioned aspect ratios and edge lengths, particularly in combination with one another, are suitable for particularly advantageous packaging of commercially available doner kebabs or dürüm snacks.

[0082] The proportions and dimensions mentioned also enable the food to be easily grasped and consumed, even if it is still within the packaging sheet or pocket area.

[0083] Particularly preferably, the proportions are selected such that 10% to 30%, preferably 20%, of the food's extent protrudes from the pocket area through the opening area. This allows consumption of the food to begin immediately after the lid area has been reopened. This is particularly advantageous in the snack food industry. As the food is consumed, it can be pushed back into the pocket area, for example, completely, and the packaging sheet can be resealed. A suitable adhesive can be provided for this purpose.

[0084] This can be done without the need for a complex folding process simply by folding the cover. Therefore, the adhesive or adhesive area is preferably reusable and adheres to the sheet multiple times.

[0085] Preferably, in the embodiments of the packaging sheet according to the invention, the sheet is made at least partially from a recycled paper material.

[0086] The invention further relates to a packaging of a foodstuff having the features mentioned in claim 14

[0087] The food packaging according to the invention is produced in at least the following steps: - Providing a packaging sheet with a preferably rectangular, flexible sheet which has a liquid-repellent coating on at least one inner side, - removing a cover element from at least one adhesive area arranged at a corner of the inner side, - Wrapping the food in the sheet so that the inside faces the food, - Attaching the adhesive area to an outer side of the sheet to ensure stable storage of the food in the wrapped sheet.

[0118] In a supply block 12, the packaging sheet 1 is provided with the preferably rectangular, flexible sheet 3, which has the liquid-repellent coating 6 at least on the inner side 5.

[0119] In a preparation block 13, the cover element 9 is removed from the at least one adhesive area 4 arranged at the corner 7 of the inner side 5.

[0120] In a wrapping block 14, the food 2 is wrapped into the sheet 3 in such a way that, preferably exclusively, the inner side 5 faces the food 2.

[0121] In a closure block 15, the adhesive area 4 is attached to the outer side 10 of the sheet 3 in such a way that stable storage of the food 2 in the wrapped sheet 3 is achieved.

[0122] Fig. 3 shows a schematic representation of a possible embodiment of the production of the packaging 11 in a front view.

[0123] Fig. 4 shows a schematic representation of a possible embodiment of the production of a packaging 11 according to the invention in a rear view.

[0124] The Fig. 3 and Fig. 4 also serve as a craft sheet by means of which a possible three-dimensional shape of the packaging 11 according to the invention can be determined.

[0125] For this purpose, the Fig. 3 and Fig. Cut out the packaging sheets 1 shown in Figure 4 along the dashed line. This is symbolized by scissors 20.

[0126] Will the Fig. 3 and Fig. 4 is printed congruently on the front and back of a sheet of paper, both the inside 5 and the outside 10 of the packaging sheet 1 can be made with one cutting process.

[0127] Preferably, the following instructions are used to carry out the crafting instructions: Fig. 3 and Fig. 4 printed congruently on the front and back of a sheet of paper made of thin paper and / or weighing 25 to 60 g / m 2 has.

[0128] To carry out the crafting instructions, a semi-solid adhesive can be applied to the circular adhesive area 4.

[0129] There are various ways of producing the packaging 11, or the handcrafted model of the packaging 11, for the food 2.

[0130] In the following, the procedure for producing the packaging 11 for a doner kebab is demonstrated by way of example.

[0131] For this purpose, the food 2 is placed centrally on the packaging sheet 1.

[0132] In a first step, the food item 2 is placed centrally on the packaging sheet 1. The food item 2, shaped like a doner kebab, should have an extension whose side length corresponds approximately to half the side length of the cut-out packaging sheet 1.

[0133] In a second step, a first corner 7a, which does not have an adhesive area 4, is folded over in the direction of the diagonally opposite second corner 7b in such a way that the packaging sheet 1 is folded over at least partially along and / or parallel to the Fig. 3 is folded and / or bent along the dot-dash line. The second corner 7b is then moved toward the original position of the first corner 7a such that the adhesive region 4, which is arranged in the second corner 7b, comes to lie approximately in a target region 21 on the outer side 10. Optionally, the adhesive region 4 can be bonded to the target region 21, in particular by pressing.

[0134] In a third step, the third corner 7c is moved towards a fourth corner 7d such that the packaging sheet 1 is folded or bent along and / or parallel to the double-dotted line.

[0135] Subsequently, the adhesive area 4 assigned to the fourth corner 7d is moved toward the original position of the third corner 7c such that the adhesive area 4 comes to rest on the second target area 22. At this point, to produce the packaging 11, the adhesive area 4 assigned to the fourth corner 7d is glued to the target area 22 on the outer side 10.

[0136] The second procedure for producing the packaging 11 concerns the case where the food 2 has a Dürüm shape.

[0137] The Dürüm snack bar is characterized by its elongated shape.

[0138] In a first step, the Dürüm, which has an axial extension of approximately 50 to 70% of a diagonal of the packaging sheet 1, is arranged parallel to the dotted line on the packaging sheet 1. The first corner 7a is then wrapped around the Dürüm, and the Dürüm is rolled along the double-dotted line such that the adhesive area 4 associated with the second corner 7b lies approximately in a third target area 23 on the outer side 10. The adhesive area 4 is then bonded to the target area 23.

[0139] In a next step, the third corner 7c is inserted into an inner area of ​​the roll formed by the packaging sheet 1. Optionally, the adhesive area 4 associated with the fourth corner 7d can now be folded over and glued to the outer side 10 to close the roll, or the roll can remain open to allow immediate consumption. By folding over the adhesive area 4 associated with the corner 7b, it can be provided that the adhesive area 4 lies in the area of ​​a fourth target area 24 on the outer side 10.

[0140] In the above-described embodiments, the adhesive area 4 does not come into contact with the inner side 5.

[0141] Whether the target areas 21, 22, 23, 24 are hit by the adhesive areas 4 depends in particular on the size of the food 2.

[0142] It can be provided that the target areas 21 to 24 are specially prepared for interaction with the respective adhesive area 4. In particular, a special roughening of the surface of the packaging sheet 1 can be provided in the area of ​​the target areas 21, 22, 23, 24.

[0143] Fig. Figure 5 shows a schematic representation of a possible embodiment of the finished packaging 11. The food product 2 (not shown) is a doner kebab. The fourth corner 7d is glued to the second target area 22.

[0144] The Fig. Figures 1 to 5 show possible embodiments of the invention in which the sheet 3 with the corresponding adhesive areas 4 can be used without further preparation. An aspect of the invention is described below in which the sheet 3 is preformed or prefolded.

[0145] Fig. 6 shows a schematic representation of another possible embodiment of the packaging sheet 1.

[0146] The packaging sheet 1 for the food 2, in particular for a snack, comprises the preferably rectangular, flexible sheet 3 for wrapping the food 2. Furthermore, one or more adhesive areas 4 are arranged on the sheet 3, which have an adhesive that adheres to the sheet 3.

[0155] Fig. 7 shows a schematic representation of another possible embodiment of the packaging sheet 1.

[0156] In the Fig. In the embodiment shown in Figure 7, the food 2 is preferably a Dürüm.

[0157] With regard to the reference symbols, reference should also be made to the Fig. 6.

[0158] Fig. Figure 7a shows a schematic representation of another possible embodiment of the packaging sheet according to the invention based on the embodiment of Fig. 7. With regard to the reference symbols, reference should therefore also be made to Fig. 6, Fig. 6a and Fig. 7. The differences to the embodiment according to the Fig. 7 will be described later.

[0159] The Fig. 6, Fig. 6a, Fig. 7 and Fig. The embodiments shown in Figure 7a preferably have the following special features: A pocket region 25 is formed in sections from a section of the sheet 3 in such a way that two parallel longitudinal edges 26 of the sheet 3 are arranged lying on themselves and are connected to one another in an at least approximately liquid-tight manner.

[0160] In other words, a part of the sheet 3 is folded over on itself and connected at the longitudinal edges 26, so that the pocket area 25 is created.

[0161] Preferably, the parallel longitudinal edges 26 of sheet 3 are bonded together in the pocket area 25 in an at least approximately liquid-tight manner. This allows the packaging sheet according to the invention to be produced particularly cost-effectively.

[0162] In the Fig. In the embodiments of the invention shown in Figures 6 to 9, an opening region 27 of the pocket region 25 is preferably formed.

[0163] In this case, a cover region 28 is preferably formed from a remaining section of the sheet 3, which can be folded over the opening region 27.

[0164] As in the Fig. 6, Fig. 6a, Fig. 7 and Fig. 7a, the at least one adhesive area 4 is preferably arranged on the cover area 28.

[0165] Furthermore, from the embodiments according to the Fig. 6 and Fig. 7 that the sheet 3 is preferably rectangular and the adhesive area 4 is arranged in the form of an adhesive strip 4 along a transverse edge 29 of the cover area 28 perpendicular to the longitudinal edges 26.

[0166] A second transverse edge 29, which is in the Fig. 6 and Fig. 7 is not provided with reference numerals for the sake of simplicity, is involved in the formation of the opening area 27.

[0167] According to the embodiments described in the Fig. 6, Fig. 6a, Fig. 7 and Fig. 7a, the sheet 3 is preferably rectangular and the dimensions are selected such that 30% to 65%, preferably 40% to 58%, particularly preferably 48% or 54% of a length of the longitudinal edges 26 contribute to the formation of the pocket region 25; and / or an aspect ratio of a length of the longitudinal edge 26 to a length of a transverse edge 29 perpendicular to the longitudinal edge 26 is 2 to 3, preferably 2.6; or 0.9 to 1.5, preferably 1.3; and / or the edge lengths of the side edges 26 and the transverse edge 29 are from 15 cm to 40 cm, preferably 20 cm to 37 cm.

[0168] In the embodiments according to the Fig. 6, Fig. 6a, Fig. 7 and Fig. 7a, the packaging sheet 1 preferably has a perforation 31b. The perforation 31b enables easy opening after sealing the packaging sheet 1 by tearing it open along the perforation 31b. This allows the food 2 to be consumed immediately.

[0169] Particularly preferred is, as can be seen from the embodiments of Fig. 6 to 7a, the perforation 31b is arranged or formed parallel to the transverse edge 29 on the pocket area 25.

[0170] It can be provided that the perforation 31b is arranged such that it is covered by the lid region 28 in the closed state or left uncovered. Preferably, the perforation 31b is arranged such that the adhesive region 4 between the perforation 31b and the opening region 27 can be applied or pressed onto the pocket region 25. If the perforation 31b is torn off, the pocket region 25 is thus torn off or shortened along the perforation 31b at its transverse edge 29 forming the opening region 27.

[0171] In an embodiment not shown, it can also be provided that the perforation 31b is formed on the lid region 28. Preferably, the perforation 31b is arranged parallel and adjacent to the adhesive region 4 on the side facing away from the transverse edge 29, so that when the packaging sheet 1 is closed, it lies on the sheet 3 in the region of the pocket region 25. This prevents liquids from escaping through the perforation 31b, while simultaneously enabling the lid region 28 to be removed by tearing off the perforation 31b. The part of the lid region 28 that comprises the adhesive region 4 preferably remains on the pocket region 25 after tearing off.

[0172] In the embodiments according to the Fig. 6a and Fig. 7a, the cover element 9 preferably has a tab 30 which projects beyond at least one of the longitudinal edges 26.

[0173] Preferably, the tab 30 is designed as an extension of the cover element 9.

[0174] Preferably, the tab 30 has an extension such that it projects 1 cm to 3 cm, preferably 1 cm to 2 cm, particularly preferably 1 cm to 1.5 cm, beyond the sheet 3 or the longitudinal edge 26 of the sheet 3.

[0175] In the in the Fig. 6a and Fig. In the embodiments shown in Fig. 7a, the tab 30 preferably has a through opening 31.

[0176] The through-opening 31 preferably has an extension corresponding to 25% to 50% of the extension of the tab 30. This ensures that the tab 30 is sufficiently stable despite the presence of the through-opening 31.

[0177] The tab 30 enables easy and secure gripping of the cover element 9.

[0178] The provision of the through-opening 31 increases a coefficient of friction between the finger of a user and the tab 30, which allows easy removal of the cover element 9.

[0179] Most preferably, a retaining element 31a can be passed through the through-opening 31. The retaining element 31a can, for example, be formed at least partially as a rope, thread, and / or wire. Preferably, the retaining element 31a can be formed at least partially in a loop shape.

[0180] In a particularly preferred embodiment, a plurality, preferably 10 to 50, particularly preferably 20 to 30, of packaging sheets 1 according to the invention can be threaded onto the holding element 31a. This creates a packaging sheet system.

[0181] The aforementioned packaging sheet system can be suspended from the holding element 31a, and each individual packaging sheet 1 can be removed from the packaging sheet system by peeling off the sheet 3 from the cover element 9, which is attached to the holding element 31a. Thus, after peeling off the sheet 3, the sheet 3 is available without the cover element 9, but with the adhesive area 4 exposed. Only the cover element 9 remains on the holding element 31a.

[0182] Therefore, the through-opening 31 is preferably designed in comparison to the tab 30 such that the material of the loop 30 is suitable for absorbing the tensile force required to pull the sheet 3 off the cover element 9 without tearing. For this purpose, the cover element 9 can be reinforced in the area of ​​the tab 30.

[0183] Fig. Figure 8 shows a block diagram of another possible embodiment of the manufacture of a package 11 (see Fig. 9) of the food 2.

[0184] In a preparation step 32, the packaging sheet 1 is prepared with the preferably rectangular, flexible sheet 3, which has a liquid-repellent coating 6 at least on the inner side 5 and which has the pocket area 25 and the lid area 28,

[0185] In a preparatory step 33, the cover element 9 is removed from at least one adhesive strip 4 arranged along the transverse edge 29 of the inner side 5 of the cover region 28.

[0186] In an insertion step 34, the food 2 is inserted into the pocket area 25 of the packaging sheet 1.

[0187] In a closing step 35, the adhesive area 4 is attached to the outer side 10 of the pocket area 25 for stable storage of the food 2 in the folded sheet 3.

[0188] Fig. Figure 9 shows a schematic representation of a possible embodiment of the finished packaging 11. The food 2 (not shown or not visible) is a doner kebab according to Fig. 6. The lid section 28 is folded over the pocket section 25 and glued there. Fig. 9 a sealed packaging sheet 1 in accordance with Fig. 6 or Fig. 6a.
