Abstract

Marked food wrapping paper is marked for genuineness by dispersing yttrium (Y), hafnium (Hf), lanthanum (La) and/or lanthanides uniformly in the paper, each in amounts less than 100 parts per million (ppm).

Description

Die Erfindung bezieht sich auf mit Echtheitskennzeichen versehenes Papier zur Umhüllung von Nahrungs- oder Genußmitteln.The invention relates to paper for wrapping provided with authenticity indicators of food or luxury foods.

Echtheitskennzeichen auf Verpackungspapier für Nahrungsmittel oder auf den Mundstücken von Zigaretten bestehen üblicherweise in einem - allenfalls verschlüsselten - Aufdruck. Um Produktimitationen, insbesondere im Zusammenhang mit berühmten Marken, wirkungsvoller entgegentreten zu können, wäre es wünschenswert, ein unsichtbares Echtheitskennzeichen für Papier mit dem erwähnten Anwendungszweck zu haben.Authenticity mark on packaging paper for food or on the mouthpieces of cigarettes usually consist of one - possibly encrypted - Imprint. To imitate products, especially those related to famous Brands to be able to face more effectively, it would be desirable to have one invisible authenticity mark for paper with the mentioned purpose to have.

Unsichtbare Echtheitskennzeichen für Dokumente wurden seit Jahrzehnten mit großem Aufwand entwickelt. Insbesondere wurde vorgeschlagen, durch Zusatz von Spurenelementen während des Papierherstellungsprozesses eine eindeutige und unlöschbare nachträgliche Identifikation des Papieres oder daraus hergestellter Produkte zu ermöglichen. Da der Nachweis der Echtheit von Dokumenten zerstörungsfrei erfolgen muß, ist die Auswahl der zugesetzten Spurenelemente beschränkt. Soweit es sich dabei um seltene Erden handelt, werden diese in einer Form eingebracht, in welcher sie fluoreszieren oder insbesondere im IR-Bereich Licht absorbieren.Invisible authenticity marks for documents have been around for decades developed great effort. In particular, it has been suggested by adding Trace elements during the paper making process a unique and indelible subsequent identification of the paper or products made from it to enable. Because the proof of authenticity of documents is non-destructive the choice of added trace elements is limited. As far as it is If rare earths are involved, they are introduced in a form in which they fluoresce or absorb light especially in the IR range.

Für die Verpackung von Nahrungs- und Genußmitteln wäre der Einbau von seltenen Erden in einem Ausmaß, welches die Erkennung aufgrund der Emission oder Absorption des unzerstörten Papiers erlaubt, schon aus Kostengründen uninteressant und toxikologisch bedenklich. Dazu kommt noch, daß die Gesetzgebung bestimmter Staaten z.B. für Zigarettenmundstücke die Verwendung von fluoreszierenden Fasern ausdrücklich untersagt.For the packaging of food and beverages, the installation would be rare Earth to an extent that is detection based on emission or absorption of the undestroyed paper allowed, uninteresting and for cost reasons alone toxicologically questionable. In addition, the legislation is more specific States e.g. for cigarette mouthpieces the use of fluorescent fibers expressly prohibited.

Die Erfindung geht von der Überlegung aus, daß bei Verpackungspapier im Gegensatz zu Dokumenten eine zerstörungsfreie Identifikation keine Bedingung für ein Echtheitsmerkmal darstellt. Es können daher zur Identifikation eines im Papier gleichmäßig verteilten Markierungsstoffes empfindliche Verfahren angewendet werden, wie optische Verfahren, welche die Emissionsspektren des in ionisierte Atome aufgelösten Papiers analysieren, oder eine massenspektroskopische Analyse der im Papier enthaltenen Elemente. Das erlaubt die Verwendung von Markierungssubstanzen in so geringer Menge, daß deren Zufügung auch für einen Massenartikel keinen erheblichen Kostenfaktor darstellt, wobei gleichzeitig die strengen Vorschriften für Lebensmittel und Zigaretten eingehalten werden können.The invention is based on the consideration that in contrast to packaging paper For documents, non-destructive identification is not a requirement for an authenticity feature represents. It can therefore be used to identify one in the paper evenly Distributed marker sensitive methods are used, such as optical Methods that resolve the emission spectra of ionized atoms Analyze paper, or a mass spectroscopic analysis of the paper contained elements. This allows the use of labeling substances in such a way small amount, that their addition is not significant even for a mass article Represents cost factor, while maintaining the strict regulations for food and Cigarettes can be kept.

Erfindungsgemäß ist somit vorgesehen, daß bei einem Papier zur Umhüllung von Nahrungs- oder Genußmitteln als Echtheitskennzeichen eines oder mehrere der Markierungselemente Yttrium, Hafnium, Lanthan bzw. Lanthanide in Mengen von jeweils unter 100 TpM gleichmäßig im Papier verteilt sind.According to the invention it is thus provided that in the case of paper for wrapping Food or luxury goods as authenticity mark one or more of the Marking elements yttrium, hafnium, lanthanum or lanthanides in quantities of are each evenly distributed in the paper under 100 ppm.

Die untere Grenze für die eingesetzte Menge an Markierungselementen ergibt sich einerseits aus dem jeweiligen Stand der Technik der Analyseverfahren für Schwermetalle. Versuche mit Konzentrationen von 1 TpM waren bereits durchaus zufriedenstellend und auch Zusätze von 0,1 TpM sind analysierbar. Bei Stoffen (z.B. Cer und Hafnium), die üblicherweise in nicht unbeträchtlichen Spuren in Papierbestandteilen, nämlich in Kaolin und Titandioxid, enthalten sind, sind allerdings höhere Konzentrationen zweckmäßig. Gerade solche Stoffe bieten sich als Markierungselemente an, da ihre toxikologische Unbedenklichkeit im Rahmen des Zusatzes von Kaolin oder Titandioxid unbestritten ist. Selbstverständlich muß bei Verwendung üblicherweise in Papier vorkommender Stoffe als Markierungselemente dafür Sorge getragen werden, daß die Markierung sich deutlich vom Hintergrund abhebt. Dies ist zumindest dann der Fall, wenn die zugesetzte Menge wenigstens der natürlichen Konzentration des Stoffes entspricht.The lower limit for the amount of marking elements used results on the one hand from the respective state of the art of analysis methods for heavy metals. Experiments with concentrations of 1 ppm were already quite satisfactory and additions of 0.1 ppm can also be analyzed. For fabrics (e.g. cerium and Hafnium), which are usually found in not insignificant traces in paper components, namely in kaolin and titanium dioxide, are, however, higher concentrations expedient. Such substances are particularly suitable as marking elements because their toxicological harmlessness in the context of the addition of kaolin or titanium dioxide is undisputed. Of course, when used, usually in paper existing substances are used as marking elements to ensure that the Mark stands out clearly from the background. At least this is the case if the amount added is at least the natural concentration of the substance corresponds.

Werden seltene Erden eingesetzt, um die zerstörungsfreie Echtheitsprüfung von Dokumenten zu ermöglichen, werden die Markierungselemente üblicherweise in Ferritgitter oder Granatgitter eingebaut, um das gewünschte Emissions- oder Absorptionsspektrum zu erzielen. Im Rahmen der Erfindung hingegen ist Fluoreszenz sogar unerwünscht, weshalb die Markierungselemente bevorzugt als Oxide in definierten Mengen als wässrige Suspension von Pulvern dem Zellstroffbrei zugesetzt werden.Are rare earths used for the non-destructive authentication of To enable documents, the marking elements are usually in Ferrite grating or grenade grating built in to the desired emission or absorption spectrum to achieve. In the context of the invention, however, fluorescence is even undesirable, which is why the marking elements are preferably defined as oxides in Amounts as an aqueous suspension of powders are added to the pulp pulp.

Die Oxide der erfindungsgemäß verwendeten Elemente weden auch in der Hochleistungskeramik bzw. anderen High-Tech-Bereichen verwendet, sodaß sie in definierten Korngrößen in der Regel im Bereich von 1-10 µm verfügbar sind. Ferner sind diese Oxide stabil und wasserunlöslich, sodaß ihre Permanenz im Papier nicht beeinträchtigt ist.The oxides of the elements used according to the invention are also used in high-performance ceramics or other high-tech areas used, so that they in defined Grain sizes are usually available in the range of 1-10 µm. Furthermore are these oxides are stable and water-insoluble, so that their permanence in the paper is not impaired is.

Überraschenderweise ist die Homogenität der Verteilung der Markierungsstoffe im Papier so gut, daß zur Analyse ein Stück von einem Quadratzentimeter Papier ausreicht. Die Retention in der Papiermaschine ist derart, daß mit Sicherheit ein Großteil des eingesetzten Materials wiedergefunden werden kann. Andererseits ist auch das Verweilen im System nicht übermäßig, sodaß nach einer weiteren Charge kein Zusatz mehr nachweisbar ist.Surprisingly, the homogeneity of the distribution of the marking substances in the Paper so good that a piece of a square centimeter of paper is sufficient for analysis. The retention in the paper machine is such that a large part is certain of the material used can be found. On the other hand, that's also Do not stay in the system excessively, so there is no addition after another batch is more detectable.

Zur Detektion der Markierungselemente bieten sich, wie gesagt, optische und massenspektroskopische Verfahren an. Die optische Analyse mit der als ICP-AES (Atomemissionsspektroskopie mit induktiv gekoppeltem Plasma) bezeichneten Methode wird allerdings dadurch erschwert, daß die im Papier vorhandenen Elemente Titan und Eisen die Markierungselemente überstrahlen. Die an sich weniger gebräuchliche und aufwendigere Detektion durch Massenspektroskopie der in einer Plasmafackel in ionisierte Atome aufgelösten Probe (ICP-MS) ist von diesem Nachteil frei.As already mentioned, optical and mass spectrometric methods are available for the detection of the marking elements Procedure. The optical analysis with that as ICP-AES (Atomic emission spectroscopy with inductively coupled plasma) However, the method is complicated by the fact that the elements present in the paper Titanium and iron outshine the marking elements. The less common in itself and more complex detection by mass spectroscopy in a plasma torch Sample dissolved in ionized atoms (ICP-MS) is free from this disadvantage.

Die Möglichkeit, aus einem Satz von beispielsweise fünf Oxiden jeweils nur einen Teil als Markierungselemente zuzusetzen, erlaubt es, das Papier eines Herstellers nicht nur als solches zu kennzeichnen, sondern beispielsweise auch den Herstellungszeitraum oder die Bestimmung für einen besonderen Kunden eindeutig im Papier festzuhalten.The possibility of only one part from a set of, for example, five oxides Adding as marking elements does not allow a manufacturer's paper only to be marked as such, but also, for example, the manufacturing period or to clearly state the provision for a special customer on paper.

Die Erfindung wird anschließend anhand von zwei Ausführungsbeispielen näher erläutert.The invention is subsequently explained in more detail using two exemplary embodiments.

Beispiel 1:Example 1:

Je 5,59g Yttriumoxid, 5,29g Hafniumoxid und 5,41g Ceroxid wurden in 200ml Wasser ausgeschlämmt und einer Langfaserpulperfüllung zugeführt. Eine Langfaserpulperfüllung führt zu ca. 4400kg Papier. Dementsprechend ist die Sollkonzentration im Papier der Elemente Y, Ce, Hf 1 TpM (unter der theoretischen Annahme von 0% Retentionsverlusten). 5.59 g of yttrium oxide, 5.29 g of hafnium oxide and 5.41 g of cerium oxide were added to 200 ml of water slurried and fed to a long fiber pulp filling. A long fiber pulp filling leads to approximately 4400kg of paper. Accordingly, the target concentration in the Paper of the elements Y, Ce, Hf 1 TpM (under the theoretical assumption of 0% Retention losses).

Aus den beiden Langfaserpulperfüllungen stammendes Papier wurde mit unmarkiertem Papier verglichen, wobei sich keine Veränderung der spezifizierten Parameter des Papiers ergab. Anschließend wurden Nullproben sowie Proben aus den beiden markierten Würfen massenspektrographisch analysiert, ohne daß das Analytiklabor über die Art der Markierungen unterrichtet war. Trotz ungünstiger Analysebedingungen ergab sich keine Überschneidung von Nullproben und markierten Proben, obwohl insbesondere im Fall von Cer der Zusatz an Markierungssubstanz kaum den natürlichen Hintergrund überstieg.

Subsequently, zero samples as well as samples from the two marked litters were analyzed by mass spectrography without the analytical laboratory being informed of the type of the labels. Despite unfavorable analysis conditions, there was no overlap between zero samples and labeled samples, although in the case of cerium in particular the addition of labeling substance hardly exceeded the natural background. element Zero samples Mark samples used kaolin used TiO2 Iron oxide Cerium (Ce 0.70-0.73 0.90-1.82 1.5-2.3 <0.1 <0.1 Hafnium (Hf) 0.02-0.08 0.34-0.80 2.1-3.0 6.2-8.1 <0.1 Yttrium (Y) 0.14-0.24 0.90-0.93 0.5-0.6 0.2-0.3 0.1 La (next move) 0.00-0.39 0.00-0.06 0.6 <0.1 <0.1 AS (next move) 0.70-1.40 0.94-1.82 0.8-1.6 <0.1 3.3-9.7

Das oben wiedergegebene Ergebnis zeigt, daß ohne Verfügbarkeit von Nullproben und in Unkenntnis der Rohstoffe etwaiger Mitbewerber eine Erhöhung der zugesetzten Menge über 1 TpM sinnvoll ist. Ein entsprechendes Beispiel wird anschließend diskutiert.The result shown above shows that without the availability of zero samples and ignorance of the raw materials of any competitors an increase in the added Amount above 1 tpm makes sense. A corresponding example is then discussed.

Beispiel 2:Example 2:

Die gleichen Elemente wie im Beispiel 1 wurden in zehnfacher Menge zugesetzt, sodaß sie theoretisch mit einem Anteil von 10 TpM im fertigen Produkt vorliegen müßten. Dies führte ebenfalls zu keiner Beeinflussung des Papiers. Die Nachweisbarkeit stieg jedoch drastisch an, wie sich aus nachfolgender Tabelle ergibt. Element 0-Pr.1 0-Pr.2 mark.
