Description
Die Erfindung betrifft die Verwendung einer thermoformbaren Kunststoffolie aus Polypropylen (PP) als Ausgangsprodukt für die Herstellung von Sortiereinlagen für die Aufnahme von Schokoladenteilen, insbesondere Pralinen.The invention relates to the use of a thermoformable Plastic film made of polypropylene (PP) as the starting product for the production of sorting inserts for the Inclusion of chocolate parts, especially chocolates.
Aus der DE 37 44 371 A1 ist eine Verpackung für Süßwaren, insbesondere Pralinen, bekannt, die aus einem Isolierbehälter und einem in diesem passend angeordneten Einsatzbehälter aus dichter Folie, insbesondere aus Polypropylen, besteht. Der Einsatzbehälter, auch Sortiereinlage genannt, ist durch Tiefziehen geformt und weist Nester für die Pralinen od. dgl. auf. PP-Folien lassen sich im Gegensatz zu Al-bedampften PVC- oder PET-Folien durch thermische Behandlung ohne die Entstehung umweltschädlicher Rückstände beseitigen; sie haben jedoch im Vergleich zu letzteren einen geringeren Oberflächenglanz-Effekt. Für die Verpackkung von Süßwaren wie z. B. Pralinen ist aber ein hoher Oberflächenglanz erwünscht.DE 37 44 371 A1 describes packaging for confectionery, especially chocolates, known from an insulated container and a suitably arranged insert container made of dense film, especially polypropylene, consists. The insert container, also called sorting insert, is formed by deep drawing and has nests for the Chocolates or the like. PP films can be Contrary to Al-steamed PVC or PET foils due to thermal Treatment without the emergence of environmentally harmful Remove residues; however they have compared to the latter have a lower surface gloss effect. For the packaging of confectionery such as B. Chocolates is a high surface gloss desired.
Aus der OS 23 62 212 sind Mehrschichtfolien bekannt, die aus wenigstens zwei Schichten aufgebaut sind, von denen wenigstens eine Schicht mit einem Pigmentanteil von 10 bis 70 Gewichtsprozent pigmentiert ist. Die Schichten können aus dem gleichen Material bestehen, bevorzugt aus Polyestern, aber auch aus Polyamiden oder Polyolefinen wie Polypropylen, die vor allem als Zeichenfolie oder Kondensatorfolie Verwendung finden. Die Schichten können auch unterschiedliche Stärken, z. B. 150 µm und 50 µm, aufweisen, wobei die dünnere Schicht als Pigment feinkörniges SiO₂, Al₂O₃, BaTiO₃, BaSO₄, TiO₂, Silikate, Glimmer oder Glaspulver enthalten kann. Damit wird bei einer Verwendung als Zeichenfolie bezweckt, Tinte oder Tusche rasch aufzunehmen, die Trocknung zu beschleunigen und die Haftung zu ermöglichen, sowie eine Bleistiftschreibbarkeit bis zu einer Bleistifthärte von mindestens 6 H zu ermöglichen. Bei einer Verwendung als Kondensatorfolie soll durch die Pigmente die Dielektrizitätskonstante erhöht werden. Der Einsatz von Perlglanz-Pigmenten wie z. B. Kombinationen von Titandioxid und Glimmer (s. Zeitschrift Kunststoff-Berater 1, 1974, S. 24-26) ist nicht erwähnt. Insoweit sind diese Mehrschichtfolien kein ausreichender Ersatz für die Eingangs genannten Al-bedampften PVC- oder PET-Folien für die Verwendung als Sortiereinlagen für Süßwaren, insbesondere Pralinen.Multi-layer films are known from OS 23 62 212, which are made up of at least two layers, of which at least one layer with a pigment content of 10 up to 70 percent by weight is pigmented. The layers can consist of the same material, preferably of Polyesters, but also from polyamides or polyolefins like polypropylene, which is mainly used as a drawing film or capacitor film Find use. The layers can too different strengths, e.g. B. 150 microns and 50 microns have the thinner layer as pigment fine-grained SiO₂, Al₂O₃, BaTiO₃, BaSO₄, TiO₂, silicates, mica or May contain glass powder. So that when used Purpose as drawing film, ink or ink quickly record, accelerate drying and adhesion to enable, as well as a pencil writability up to a pencil hardness of at least 6H. When used as a capacitor film the dielectric constant is increased by the pigments become. The use of pearlescent pigments such. B. Combinations of titanium dioxide and mica (see magazine Plastic consultant 1, 1974, pp. 24-26) is not mentioned. In this respect, these multilayer films are not sufficient Replacement for the Al-steamed PVC or PET films for use as sorting pads for confectionery, especially chocolates.
Ausgehend von dem eingangs zitierten Stande der Technik hat die Erfindung die Verwendung einer PP-Folie für die Herstellung von Sortiereinlagen zur Aufnahme von Schokoladenteilen, insbesondere von Pralinen, zum Ziel, bei der der Oberflächenglanz-Effekt erhöht ist und die daher als Ersatz für Al-bedampfte PVC- oder PET-Folien verwendet werden können.Based on the prior art cited at the beginning the invention has the use of a PP film for the Manufacture of sorting inserts to hold chocolate parts, especially from chocolates, to the goal at which the surface gloss effect is increased and therefore as Substitute for Al-vaporized PVC or PET foils used can be.
Erfindungsgemäß wird dies durch die Verwendung einer coextrudierten PP-Verbundfolie aus zwei Schichten erreicht, von denen die eine Schicht um ein mehrfaches dicker ist als die andere, wobei die dünnere Schicht bis zu 10% Volumenanteil Unteransprüche beinhalten vorteilhafte Weiterbildungen und Ausgestaltungen für diesen Verwendungszweck.According to the invention, this is achieved through the use of a coextruded PP composite film achieved from two layers, one of which is several times thicker than the other, with the thinner layer up to 10% by volume Subclaims contain advantageous developments and configurations for this purpose.
Die in dieser Weise modifizierte PP-Folie und die hieraus hergestellten Sortiereinlagen haben einen perlmuttartigen Oberflächenglanz ohne Trübung. The PP film modified in this way and the one from it Sorting inserts produced have a mother-of-pearl Surface gloss without cloudiness.
Durch die zusätzliche Einfärbung der dickeren Schicht mit normalen Farbpigmenten kann eine Farbwertigkeit der Verbund folie von hellgold bis zum dunkelgold verändert werden. Je nach Einfärbung der dickeren 200-250 µm dicken Schicht wird mit weiß die Farbe hellgold, mit rauchgrau bis braun die Farbe dunkelgold und mit bordeauxrot die Farbe rotgold erzielt. Die relativ teuren Perlglanz-Pigmente befinden sich nur in der dünneren, bis zu 50 µm dicken Schicht. Diese Pigmente können in dieser dünneren Schicht eine hohe Konzen tration von bis zu 10% Volumenanteil haben, so daß keine Trübung mehr auftritt, die Gesamtkosten aber trotzdem nicht wesentlich ansteigen, da die Ausgangsstoffe für PP-Folien billiger sind als für PVC- der PET-Folien.Through the additional coloring of the thicker layer with normal color pigments can give the composite a color value foil can be changed from light gold to dark gold. Each after coloring the thicker 200-250 µm thick layer with white the color is light gold, with smoky gray to brown the color dark gold and with burgundy the color rose gold achieved. The relatively expensive pearlescent pigments are located only in the thinner, up to 50 µm thick layer. This Pigments can have a high concentration in this thinner layer tration of up to 10% by volume, so that none Turbidity occurs more, but the total cost does not increase significantly since the raw materials for PP films are cheaper than for PVC or PET films.
Die Herstellung der Verbundfolie erfolgt nach bekannten Methoden, wie sie z. B. im Saechtling-Kunststoff-Taschenbuch, 22. Ausgabe, Seiten 157 und 158, dargestellt und beschrie ben sind. Für das Coextrudieren werden wenigstens zwei Ex truder verwendet, einer für die dünne, ca. 50 µm dicke, mit Perlglanz-Pigmenten eingefärbte PP-Folie, und einer für die dicke, ca. 200-250 µm dicke PP-Folie, die mit zusätzlichen, normalen Farbpigmenten versetzt sein kann. Beide Schmelzströme werden in einem gemeinsamen Breit schlitz-Düsensystem zusammengeführt und sodann z. B. nach dem Chill-Roll-Verfahren weiterverarbeitet. Die so herge stellte Verbundfolie kann sodann mittels Thermoformmaschi nen zu Sortiereinlagen für die Aufnahme von Schokoladeteilen, insbesondere von Pralinen, tiefgezogen werden.The composite film is produced according to known ones Methods such as B. in the Saechtling plastic paperback, 22nd edition, pages 157 and 158, shown and described ben are. At least two Ex truder used, one for the thin, approx. 50 µm thick, PP film colored with pearlescent pigments, and one for the thick, approx. 200-250 µm thick PP film that with additional, normal color pigments can be offset. Both melt streams are in a common breadth slot nozzle system merged and then z. B. after processed the chill roll process. The herge The composite film can then be placed using a thermoforming machine sorting inserts for the admission of chocolate parts, especially of chocolates.
