    Description TECHNICAL AREA
    The present invention relates to a banderole for baked goods, a printed paper tape in roll form, which can be subdivided into bands, a method for the production of banderols for baked goods, and a method for providing a baked good with a band.
    STATE OF THE ART
    In recent years, more and more bakeries have begun to provide bread with bands of paper. The banderoles are usually printed in one color or multi-colored. In the market, breads with banderols are often perceived as having a particularly high quality and freshness. By bandering their breads, a bakery can give the consumer special confidence and a positive image. In addition, banderols can also serve to inform about the content and nutritional value and to provide further information on the bread.
    Traditionally, a banderole is attached to the bread only after the bread has been baked. Commercially available banderoles for bread are e.g. made of paper, which is provided on one side with a continuous coating of polyethylene. To attach the band, it is placed around the bread by a banding machine, and its end portions are welded together by means of a hot stamp of the banding machine. The polyethylene coating melts in the area of the hot stamp and penetrates into the near-surface areas of the adjacent paper layers. The basis weight of the polyethylene coating is typically in the range of 20 g / m 2.
    In recent years, a need has arisen to attach banderoles already on partially baked breads and deliver in this form to the point of sale. The breads are then baked ready at the point of sale and go immediately afterwards in the sale. The baking temperatures are usually in the range between 170 ° C and 200 ° C. Such a procedure is particularly interesting for large bakeries, which deliver their partially baked bakery products to a variety of outlets such as supermarkets, where the baked products are then freshly baked as needed.
    However, conventional bands are not suitable for such a method. Conventional banderoles are not sufficiently heat-resistant for this purpose. In particular, the polyethylene coating melts at such high temperatures and can get on the bread. The polyethylene coating can also outgas at these temperatures and thereby also contaminate the bread. In addition, the banderols commonly used tend to discolour strongly during the baking process ("browning").
    From EP 2 574 565 A1 a baking bag is known, which is made of glassine paper whose front wall is formed of a plastic film. The glassine paper and the plastic film are connected together by means of a polyurethane hotmelt adhesive.
    EP 189 471 A1 discloses a bag for pre-baked baked goods, which is at least partially made of a composite paper, wherein a PUR adhesive is laminated on the composite paper. The PUR adhesive also serves to connect a plastic film with the composite paper.
    PRESENTATION OF THE INVENTION
    Starting from the above-mentioned polyethylene-coated banding tapes, it is an object of the present invention to provide a banding in which contamination of the baked good by a polyethylene coating is avoided when the baked good is ready baked together with the band.
    This object is achieved by a band according to claim 1. Further embodiments are given in the dependent claims.
    There is thus provided a banderole for baked goods, which comprises: an elongate paper strip, wherein the paper strip has a top side, a bottom side and with respect to its longitudinal direction a first and a second end region; a first print made of at least one ink; and a second print formed of an adhesive to bond the first and second end portions together.
    Thus, according to the invention, an adhesive is printed on the paper strip. As a result, the disadvantages of a full-surface, continuous polyethylene coating, as known from the prior art, avoided. In particular, the locations where adhesive is provided, the amount and distribution of the applied adhesive can be adjusted specifically. In particular, it is possible to selectively apply the adhesive only where the band is to be closed, namely in the end regions of the paper strip. It is also possible to print the adhesive in the form of individual structural elements such as pixels or lines. As a result, the amount of the applied adhesive can be greatly reduced compared to a full-surface coating. In this way, it is possible to prevent the adhesive from getting onto the baked good when baking the baked good, even if the printing with the adhesive is not restricted to the end regions of the banderole.
    For the expert is readily ascertained whether the adhesive was applied by way of printing or other means. Thus, each printing process produces a characteristic printed image as well as characteristic marks on the paper which make it possible to determine on the finished banderole which printing process has been used. This is well known to the skilled person.
    Preferably, the second printing with the adhesive is applied only after the first depression. It may overlap with the first print and in that case it will be above the first print. The first print may include, for example, graphic elements, information about the bakery, the composition and nutritional value of the baked goods, etc.
    As a base material for the paper strip, a paper based on finely ground pulp is preferably used, preferably a paper without further additives. The paper is preferably sharpened satin and thus at least partially transparent. Particularly preferred is a glassine paper. Experiments have shown that glassine paper maintains an attractive appearance at the temperatures at which bakery products are usually baked, and in particular only little to no after-browning. In particular, glassine papers are available which are harmless under food law. Glassine papers are also particularly suitable for printing, especially in flexographic printing.
    Preferably, the adhesive is a Fleisssiegellack which is formed for welding the first and the second end portion under the action of heat. This makes it possible to use conventional banding machines for attaching the bands.
    Advantageously, the adhesive is printed in the form of a (in particular aqueous) polymer dispersion on the paper strip, and the paper strip is then dried. In particular, it may be a thermoplastic reactivatable polymer dispersion, i. to a polymer dispersion which forms a thermoplastic polymer layer after drying, which is reactivated by the action of heat. Such a thermoplastic polymer layer is an example of a Fleisssiegellack. The polymer dispersion may in particular be a polyurethane dispersion, an acrylate dispersion or an ethylene vinyl acetate (EVA) dispersion. Polyurethane is preferred for its durability.
    The adhesive on the paper strip in the dry state preferably has a weight per unit area of 1-10 g / m 2, preferably 2-5 g / m 2. When the adhesive is formed from a polymer dispersion, the coating weight of the polymer dispersion in the wet state can be correspondingly about 4-40 g / m 2, preferably 8-20 g / m 2.
    It is advantageous if the first printing, which is formed from ink, and the second Oppression, which is formed from the adhesive, are applied in similar printing processes on the paper strip. Preferably, the adhesive is printed on the paper strip in a Flochdruckverfahren, in particular in the flexographic printing process. Flexographic printing is preferred because this technique is often used to print the inked print on the paper strip as well. Thus, the same printing machines that are used for printing with ink can also be used to apply the adhesive. Alternatively, e.g. Screen printing can be used.
    To be suitable for the job with flexographic printing, the viscosity of the adhesive should be sufficiently low. The viscosity can be determined according to DIN EN ISO 2431: 2011 in particular with the aid of an outlet cup having an opening with a certain diameter. Ideally, the flow time with ISO 5 mm cups should ideally be no more than approx. 90 seconds. But it can also be worked with higher viscosities.
    As already mentioned, it is advantageous if the adhesive forms on the paper strip an arrangement of a plurality of structural elements, in particular an arrangement of a plurality of pixels. Such an arrangement makes it possible to greatly reduce the amount of the adhesive compared to a full-surface application. Such an arrangement can be made meaningful only by printing.
    In order to avoid that the adhesive comes into contact with the baked good, it is possible to print the adhesive exclusively on the top of the paper strip. In this case, the top side of the paper strip is to be understood as that side which points away from the baked product after the banderole has been attached to the baked goods. As a rule, the first print is applied to the upper side, which carries the information about the baked goods.
    In other embodiments, the adhesive is printed on both sides of the paper strip. In this case, it is advantageous if the adhesive is printed on the underside of the paper strip exclusively in the second end region, because in this area, the band is finally closed, in which case the second end portion rests with its underside on top of the first end portion. On the upper side of the paper strip, the adhesive is then preferably printed only in the region of the first end region, so that in each case adhesive is present when closing the band on the two mutually facing sides of the end regions. However, it is also possible to additionally print the adhesive outside of the first end region, even if this does not usually make sense.
    It is also specified a printed paper tape in roll form, which is subdivided into a plurality of bands of the aforementioned type. The paper tape defines a running direction and can be divided into banderoles of the aforementioned type in particular by cuts made transversely to the running direction. Optionally, it may previously be necessary to make cuts along the longitudinal direction to first divide the paper tape into a plurality of parallel sub-bands.
    In order to control the cut of the paper tape in the banding machine, a plurality of control marks may be printed on the paper tape, wherein the control marks indicate cutting positions for the cuts transversely to the running direction.
    Furthermore, a method for producing a band of the aforementioned type is given. The method comprises:
    Providing a paper web in roll form, wherein the paper web is preferably formed from a paper based on ground pulp;
    Printing the paper web with a first print of at least one printing ink; and printing the paper tape with a second printing from an adhesive, wherein the printing of the paper tape with the adhesive takes place such that bands of the aforementioned type are obtainable by a division of the paper tape.
    The above considerations for the actual banderole apply mutatis mutandis to the process for producing such a banderole. The method may include a step of dividing the paper web after application of the first and second printing into a plurality of banderoles according to any one of the preceding claims, in particular by cuts made transverse to the direction of travel.
    Finally, a method for processing a baked good, in particular a bread specified. In this method, a still open banderole of the type described above is placed around the baked good, and then the end portions of the banderole are welded together by means of the printing from the adhesive to close the banderole around the baked goods around.
    As has already been explained, the present invention makes it possible that the band is attached to the baked good, while the baked good is only partially baked, and that the partially baked baked good is baked after attaching the band.
    BRIEF DESCRIPTION OF THE DRAWINGS
    Preferred embodiments of the invention are described below with reference to the drawings, which are merely illustrative and not restrictive interpreted. In the drawings show:
    Figure 1 shows a bread with attached banderole.
    Fig. 2 is a schematic plan view of a printed paper tape which can be divided into bands;
    Fig. 3 is a highly schematic and not true to scale sectional view of the band in the plane A-A of Fig. 2; and
    Fig. 4 is a schematic illustration of a flexographic printing process for printing a paper tape. DESCRIPTION OF PREFERRED EMBODIMENTS
    Fig. 1 illustrates an example of a bread 1 with attached banderole 2. The banderole consists of a paper strip 20 of glassine paper, which was printed with an end user printing 21 in single or multi-color flexographic printing process. On the underside of the bread, the ends of the paper strip are connected together in the manner explained in more detail below.
    In Fig. 2 a printed paper tape 3 is exemplified in plan view. The paper tape 3 can be subdivided with respect to the longitudinal direction L into a plurality of mutually adjacent bands 2, wherein the corresponding cutting lines 26 extend transversely to the longitudinal direction L. Each of the banderoles 2 is provided on the top of the paper strip 20 with the end user print 21. The paper strip 20 has a first end 23 and a second end 24. In the region of the first end 23, a printing 22 made of an adhesive, here a hot-sealing lacquer, is printed on the upper side of the paper strip 20. Since the print 22 consists of a paint, one would have to speak strictly speaking of a paint job; However, the term "printing" is used throughout this document.
    To display the cutting positions, 3 more control marks 25 are printed on the top of the paper tape, which are reproduced here only in a highly schematic form. During the processing of the paper tape 3, the banding machine optically recognizes these control marks and performs the cuts to separate the bands corresponding to the cutting lines 26. Of course, the tax stamps may have a shape other than that shown here and offset to be printed later cut line.
    Fig. 3 shows the printed paper tape 3 in a highly schematic form in a longitudinal section along the cutting plane A-A. This representation is not true to scale. In particular, the thickness of the paper tape is greatly exaggerated. As can be seen from Fig. 3, in the region of the second end 24 on the underside of the paper strip 20, a further print 27 is printed from the Heisssiegellack. As is also indicated in FIG. 3 in a very highly schematic form, each of the imprints 21, 22 and 27 consists of a large number of structural elements 28, here in the form of pixels which are separated from one another by unprinted areas. The structural elements can also be lines or other structures. The structural elements preferably have dimensions of less than 1 mm with respect to at least one dimension in the plane of the paper. When the features are pixels, each pixel preferably has an area of less than 1 mm 2, more preferably less than 0.1 mm 2. But it is also partially or continuously a full-surface printing possible.
    To provide a bread 1 or another baked good with the band 2, the printed paper tape 3 is inserted into a known banding machine. With the help of the banding machine, the paper tape 3 is brought around the bread until the top of the first end 23 overlaps with the underside of the second end 24 of a paper strip 20. Now the banding machine welds the first end 23 and the second end 24 by means of a hot stamp or by ultrasound application. In the process, the hot-sealing lacquer melts in the printings 22 and 27 and connects to the two ends 23 and 24 of the paper strip 20 in order to produce a permanent connection between the two ends 23 and 24.
    Both the end user printing 21 and the printings 22 and 27 with the hot-seal lacquer are preferably printed on the paper tape 3 in the flexographic printing process. The flexographic printing process is a web-fed rotary printing process that employs flexible printing plates, usually made of photopolymer or rubber. It is a high pressure process, i. the raised areas of the printing form are image-bearing.
    The flexographic printing unit comprises an anilox roller, via which the printing form is inked, a printing form cylinder, on which the printing form is fixed, and an impression cylinder, which guides the printing material. In the surface of the anilox roller are tiny, even wells or cells (domes), sometimes also lines (Ha-shur), which are engraved by means of various engraving processes. The non-recessed areas are called webs, the wells usually wells. There are several methods to color the anilox roller. Differences are in this case in particular the diving roller printing unit and the chamber doctor blade printing unit.
    FIG. 4 schematically illustrates a dip roll printing unit 4. The ink (for the end user printing 21) or an aqueous polyurethane-based dispersion (for the prints 22 and 27 with the hot seal coating) is placed in a paint trough 41. A fountain roller 42 immersed in the ink or dispersion and takes these on their surface. From the fountain roller 42, the ink or dispersion is transferred to an anilox roller 43, where excess ink or dispersion is removed with a doctor blade 44. From the anilox roller 43, the printing ink or dispersion reaches the printing form cylinder 45, which carries the actual printing form. The paper tape 3 to be printed is provided on a roll 31. For printing, it is passed between the printing form cylinder 45 and a counter-pressure cylinder 46. Several such printing units can be arranged one behind the other in order to successively apply a multicolored printing and finally the printing with the hot-sealing wax lacquer.
    The printing form consists in flexographic printing of a relatively soft material. As already described, the areas that serve for printing are raised (high-pressure method). To illustrate the printing process, a raised area 37 of the printing form is symbolically indicated, which generates a structural element 28 on the paper tape.
    Instead of a dipping roller printing unit, a chamber doctor blade printing unit can also be used. There are many variations of such printing units, and the invention is in no way limited to a particular type of printing unit.
    As a hot-sealing wax is preferably a paint based on an aqueous polyurethane dispersion used. Such hot seal coatings are available on the market that meet the relevant food contact regulations, e.g. EU Regulations 1935/2004 and 10/2011, the Swiss Commodities Regulation SR 817.023.21 and paragraphs 175.105 and 176.180 of Chapter 21 of the American CFR (Code of Federal Regulations).
    Instead of a lacquer based on an aqueous polyurethane dispersion, e.g. Another paint based on an aqueous polymer dispersion (for example acrylate or EVA) may also be used as long as it complies with the relevant foodstuffs regulations, is suitable for application by a printing process and is suitable for use with conventional banding machines.
    The paper tape is made of a glassine paper. Glassine papers and their preparation are known in the art. Glassine paper is made from finely ground pulp. Preferably, it is free of other additives. It is sharply satined and thus obtains transparent properties. Commercially available glassine papers

    which have been approved in accordance with the relevant regulations for contact with food, for example according to EU Regulation 1935/2004 or the German Food, Commodities and Feed Code. The basis weight of particularly suitable glassine papers is in the range of 40-150 g / m 2, preferably in the range of 60-100 g / m 2, more preferably in the range of 70-90 g / m 2, determined according to ISO 536: 2012. Preferably, a glassine paper is used which has not been surface-treated with other substances, in particular has not been treated with silicone substances or with fluorinated substances. While in the example shown above, the paper tape 3 is divided by means of tax stamps 25 in equal length strips of paper and only the end portions of each paper strip are printed with the Heisssiegellack, it is also possible, the paper tape on its upper side and outside the end regions, in particular consistently, with the Heisssiegellack to print. This is particularly interesting when the end user print is designed as a repetitive, endless print that can be separated at any point. In this case, tax stamps can be dispensed with, and breads of different sizes can be banded with the same paper tape. The banding machine can be designed accordingly simpler, since they need not be able to recognize tax stamps. As paper tapes bands of various widths can be used, in particular in the range of 10 mm to 430 mm. Typical widths are between 25 and 100 mm. Commonly used widths for banding machines are e.g. 28, 29, 30, 40, 47, 48, 50, 54, 60, 65, 72, 75, 97 and 100 mm. The paper tape is delivered as a roll, the roll being a length of e.g. 1000 running meters can have.
