WRAPPING MATERIAL FOR PACKAGED GOODS AND STACKS, INCLUDING A VARIETY OF THESE WRAPPING MATERIALS, AS WELL AS USE OF THE WRAPPING MATERIAL

Description

[0001] The present invention relates to a wrapping material for packaged goods, preferably for food products, and particularly preferably for fast food products. The invention further relates to a stack comprising a plurality of wrapping materials according to the invention. The invention also relates to the use of the wrapping material according to the invention for packaging food products.

[0002] Wrapping paper for food has long been used in both private and commercial settings, for example, to wrap foods like cheese or sausage. Accordingly, wrapping paper is regularly found in butcher shops, delicatessens, and fishmongers. This wrapping paper is usually grease-resistant. The size and format of the wrapping paper must be appropriate for the food being wrapped.

[0003] In contrast, folded boxes made of paper or cardboard are currently used for packaging ready-to-eat cooked or reheated foods such as burgers or pizzas. The size of these containers is adapted to the food being packaged. Their production is technically complex and often material-intensive. Furthermore, such product packaging sometimes features viewing windows made of plastic film. This makes single-material recycling difficult or even impossible.

[0004] It would be desirable to have access to wrapping papers that are characterized by a very broad range of applications. Therefore, the present invention was based on the objective of making wrapping papers available that are not subject to the disadvantages of the prior art and that, in particular, allow for the uncomplicated wrapping of any ready-to-eat foodstuffs and dishes.

[0005] Accordingly, a wrapping material for packaged goods, preferably for food and especially preferably for fast food, was found, comprehensive (i) a wrapping film comprising or representing a plastic film, or a wrapping paper comprising or consisting of a single- or multi-layered paper, in particular a wrapping paper, with an inner and a facing outer side, a first and an opposite second edge, and opposite first and second side edges extending from the first to the second edge, and (ii) a band present on the outer side of the wrapping film or the wrapping paper, in particular the wrapping paper, having a first end and an opposite second end extending from the first edge to the second edge, beginning with the first end, wherein the wrapping film or the wrapping paper, in particular the wrapping paper, has a fold or crease line extending from the first side edge or spaced apart from the first side edge to the opposite side edge or in the direction of the second side edge,which is closer to the first edge than to the second edge, and which extends from the first edge of the page to the opposite second edge.

[0006] Because the fold line is positioned closer to the first than to the second edge of the wrapping film or paper, this wrapping film or paper is divided into a shorter first section and a longer second section. The first section typically has a smaller area than the second section.

[0007] According to the invention, a fold is present when it has been produced using a tool or machine specifically designed for this purpose. Such machine-produced folds are typically formed in the form of a crease. If such a crease is produced without the aid of a tool, it is considered a fold according to the invention. The fold is applied to, or is located on, the inside of the wrapping film or wrapping paper, particularly the wrapping paper. For the purposes of the invention, "inside" refers to the side facing away from the band.

[0008] By equipping the wrapping film, in particular the wrapping paper, with a band, the wrapping material can have a neutral appearance, while the band can be printed or otherwise designed. Since the wrapping film, in particular the wrapping paper, of the wrapping material according to the invention does not need to be printed or colored, no special format requirements generally need to be observed with regard to the wrapping film or wrapping paper. To give the wrapping material according to the invention a characteristic appearance, it is sufficient to use a colored or printed band. This can be produced separately and attached to the wrapping film or wrapping paper after completion. This approach enables flexible production of a wide variety of bands combined with simple stocking of a manageable selection of wrapping films or wrapping papers.

[0009] Due to printing limitations, a narrow border area at one end of the band often remains unprinted or white, i.e., the color of the band's base material. According to the invention, this incompletely printed side of the band is selected such that it is located in a section at or near the first end of the band. Accordingly, it is preferable for the printed side of the band to be unprinted or white in a section at or near the first end. According to the teaching of the present invention, the second end of the band is designed to coincide with the second edge of the wrapping paper or film, or for the second end of the band and the second edge of the wrapping paper or film to be aligned. In conjunction with the fold or crease line, this ensures that when the product is wrapped or...When packaging goods, especially food, the unprinted or white area is always covered by the wrapping paper or film. This is achieved by providing a fold line, which is located closer to the first edge of the wrapping paper or film than to the second. This ensures that the product, for example, a burger, is placed on the longer or larger second section of the wrapping paper or film adjacent to the fold line. The second section is thus wrapped over the shorter first section underneath. The packaged product therefore always has a flawless, pristine appearance. The perceived value of the packaged product is thus no longer diminished by imperfect packaging.

[0010] In a preferred embodiment, the wrapping film of the wrapping material according to the invention is a plastic film or is predominantly made of one. Preferably, the wrapping paper is selected from the group consisting of glassine paper, parchment substitute paper, greaseproof paper or oil-coated paper, in particular palm oil-coated paper, and paraffin-coated paper. Alternatively, conventional or untreated paper as well as recycled paper can also be used for the wrapping paper.

[0011] The band is made of paper, especially recycled paper, or plastic, with paper being particularly preferred. Suitable basis weights for the wrapping paper range from 20 to 100 g / m². The thickness of the wrapping film is advantageously in the range of 5 to 100 µm. In advantageous embodiments, the band has a basis weight in the range of 20 to 150 g / m². Polyolefin films are preferably used for the wrapping film, with polyethylene films being particularly preferred. So-called co-extruded films can also be used.

[0012] The band is preferably positioned centrally between the first and second edge of the page. The width of the band is advantageously less than the shortest distance between the first and second edge of the page, in particular less than half as wide and most preferably at most one-third as wide as this shortest distance.

[0013] The fold line of the wrapping paper or film preferably runs substantially parallel, in particular parallel, to the first edge or substantially parallel, in particular parallel, to the second edge. It is particularly advantageous for the fold line of the wrapping paper or film to preferably run substantially parallel, in particular parallel, to the first edge and substantially parallel, in particular parallel, to the second edge. In the two embodiments mentioned above, the fold line of the wrapping paper or film preferably runs perpendicular to the first or second edge, and in particular perpendicular to both the first and second edges. For many applications, the basic shape of the wrapping paper and film is preferably a square or a rectangle, with the rectangular shape being preferred for many packaged goods, especially food products.To ensure particularly reliable and complete packaging, it has proven especially advantageous for the fold or crease line to extend from the first side edge to the opposite second side edge.

[0014] Particularly reliable packaging is ensured by the fact that the fold or crease line has a distance from the first edge that is in the range of 1 / 8 to 4 / 9, and in particular up to 2 / 5, of the distance between the first and second edges (16). For many applications, it has proven advantageous for the aforementioned embodiments if the distance from the fold or crease line to the first edge of the wrapping paper or film is in the range of 8 to 16 cm, and in particular in the range of 10 to 12 cm. The width of the wrapping paper and the wrapping film, i.e., the shortest distance between the first and second edges, can be varied over a wide range and adapted to the size of the product being packaged, especially food, so that complete packaging is always achieved. Naturally, the length of the wrapping paper or film can also be varied.The wrapping film can be varied in many ways, especially taking into account the size of the respective packaged goods.

[0015] The band is attached to the outside of the wrapping film or, in particular, the wrapping paper. For many applications, it has proven advantageous to affix the band to the outside of the wrapping film or paper. Surprisingly, this can also be integrated into a fully automated mass production process.

[0016] With the present invention, the band is preferably printed, particularly on the side facing away from the outside of the wrapping paper or film. In this way, the graphic design or printing of the wrapping film or paper can be dispensed with. Instead, it is sufficient to print only the side of the band facing away from the outside of the wrapping paper or film, or to otherwise design or decorate it with color and / or a pattern.

[0017] For many applications, it has proven advantageous to position the band essentially centered, particularly between the first and second edges of the packaging. This regularly results in a visually appealing packaging of the food product. It also provides a particularly stable package. Furthermore, it reliably protects the user's fingers from any liquid that might seep through the wrapping paper when handling the packaged food.

[0018] A particularly visually appealing and user-friendly wrapping material is obtained by extending the banderole from the first edge to the second edge of the wrapping paper.

[0019] The wrapping material according to the invention can be used for both manual and automated packaging of goods such as food. The folding or creasing allows the goods to be aligned along the fold, resulting in particularly high repeatability of the packaging. This generally has a very positive effect on the visual appearance and stability of the packaging. Furthermore, the folding or creasing already present in the wrapping material according to the invention reduces the time regularly required for packaging the goods.

[0020] The problem underlying the invention is further solved by a stack comprising a plurality of wrapping materials according to the invention. In one embodiment, the wrapping materials in this stack are arranged completely spread out one on top of the other, with the fold or crease already formed. Alternatively, the wrapping materials according to the invention may be arranged in the stack already folded along the crease or crease. In one embodiment, the wrapping materials folded along the crease or crease may be arranged one on top of the other in the same orientation. Alternatively, the wrapping materials folded along the crease or crease may be stacked alternately, each rotated by 180°.This 180° rotation can be performed alternately arc by arc of the impact material, or in layers of two or more arcs alternating.

[0021] Further features and advantages of the invention will become apparent from the following description, in which exemplary embodiments of the invention are explained by way of example with reference to schematic drawings, without thereby limiting the invention. The drawings show: Figure 1 shows a first embodiment of an impact material according to the invention in a top view of the outside, Figure 2 shows a second embodiment of an impact material according to the invention in a top view of the outside, Figure 3 shows the second embodiment of the impact material according to the invention in a top view of the inside, Figure 4 shows a schematic perspective view of the second embodiment of the impact material according to the invention, Figure 5 shows a schematic side view of a first embodiment of a stack of impact materials according to the invention, and Figure 6 shows a schematic side view of a second embodiment of a stack of impact materials according to the invention.

[0022] Out of Figure 1A first embodiment of a wrapping material 1 according to the invention is shown. This wrapping material can be used, for example, for packaging ready-to-eat foods such as fast food. The wrapping material 1 according to the invention is described in Figure 1The illustrated embodiment comprises a wrapping paper 2, the outer surface 12 of which faces the observer. This wrapping paper 2 has a first edge 14 and an opposing second edge 16, as well as opposing first and second side edges 18 and 20. In the illustrated embodiment, these extend from the first to the second edge 14 and 16, respectively. The first edge 14 and the second edge 16 represent the narrow sides in the illustrated embodiment of the wrapping material 1 according to the invention. The wrapping material 1 according to the invention also includes a strip of material 22 on the outer surface of the wrapping paper 2 in the form of a band that is printed completely on at least the outer surface. This band has a first end 24 and an opposing second end 26, as well as a first side edge 34 and an opposing side edge 36.The band 22 accordingly extends with its first end 24 from the first edge 14 of the wrapping paper 2 to the second edge 16. The second edge 16 of the wrapping paper 2 is expediently aligned with the second end 26 of the band 22. The wrapping paper also has a fold line 28 extending from the first side edge 18 to the second side edge 20. This fold line 28 divides the wrapping paper 2 into a smaller first section 40 and a larger second section 42. This fold line is shown in the figure below. Figure 1 In the illustrated embodiment, it was applied to the inner surface 10 opposite the outer surface 12. Figure 1Looking at the outer surface 12 of the wrapping material 1, the band 22 is, in the illustrated embodiment, affixed to the outer surface 12 of the wrapping paper 2. It has proven advantageous to position the band 22 centrally between the first and second edges 18, 20. The width of the band 22 is typically less than the shortest distance between the first and second edges 18, 20, and in particular, significantly less than this shortest distance.

[0023] Figure 2 Figure 1 shows a second embodiment of an impact material 1 according to the invention, also in a top view of the outer surface 12 thereof. In contrast to the impact material of the Figure 1 The banderole 22 is unprinted in section 32, which is located at the first end 24, while the remaining outer part of the banderole is printed. The fold line 28 is again applied to the inside. Figure 3 shows a top view of the inside of the impact material 1 according to Figure 2 In this embodiment, the goods to be packaged are regularly placed on this inner side adjacent to the fold line 28 on the larger second section 42 in order to wrap and package them with the wrapping material 1. In the embodiment according to Figure 3 The adhesive strip 38 is also shown, with which the banderole 22 is attached to the outside 12 of the wrapping paper 2.

[0024] Figure 4 The impact material 1 is shown according to the Figure 2 and 3in a configuration where, due to the fold line 28 applied on the inside, it is in a pre-folded form or can be easily folded into this form due to this fold line. Because of the different sizes of the first and second sections 40, 42, the packaged goods will be placed on the inside of the larger section 42 to achieve effective wrapping adjacent to the fold line 28. In this process, the shorter section 40, containing the unprinted section 32 in the band 22, will be wrapped by the longer or larger section 42 and thus remain concealed. This ensures a consistently flawless design.

[0025] Figure 5Figure 1 shows a schematic side view of a first embodiment of a stack of wrapping materials according to the invention, as it may be present, for example, in a cardboard box for transport or for removal at the point of use. The individual wrapping materials are already pre-folded along the fold line 28 in the stack. The outer side of the longer section 42 rests on the outer side of the shorter section 40. The wrapping materials are arranged such that all shorter sections 40 are overlapping. Of course, it is also possible to fold the wrapping materials in the stack in the same way. Figure 5 The stack shown is to be placed in a cardboard box rotated by 180° so that the shorter section 40 always lies below the longer section 42 of the same wrapping material sheet.

[0026] Figure 6shows a further embodiment of a stack of impact materials according to the invention in a schematic side view. In contrast to the stack according to Figure 5 The individual wrapping materials are arranged alternately with respect to the orientation of the folded shorter section 40. This applies both when using the stack according to Figure 5 as well as when using the stack according to Figure 6 When a user removes the item by grasping the shorter first section 40, the larger second section 42 immediately provides a support surface for the packaged goods. This significantly facilitates the flawless packing process.

[0027] The features of the invention disclosed in the foregoing description, in the claims and in the drawings can be essential for the realization of the invention in its various embodiments, both individually and in any combination.
