Die Erfindung betrifft mehrschichtige Wursthüllen aus thermoplastischen Kunststoffen, vorzugsweise Polyamiden, insbesondere eine zweischichtige Hülle, deren Innenschicht aus Nylon 12 oder Nylon 11 und deren Außenschicht aus Nylon 6 besteht.The invention relates to multilayered thermoplastic sausage casings Plastics, preferably polyamides, in particular a two-layer cover, the inner layer of which is made of nylon 12 or nylon 11 and its outer layer consists of nylon 6.
Es ist bekannt, einschichtige Schlauchfolien aus thermoplastischen Kunststoffen, wie Polyäthylen oder Polyamiden, wegen ihrer Wasserdampf- und Luftundurchlässigkeit für Verpackungszwecke, unter anderem auch als Wursthüllen zu verwenden. So wird als Wursthülle eine Schlauchfolie aus Nylon 12 eingesetzt.It is known, single-layer tubular films made of thermoplastic Plastics such as polyethylene or polyamides can be used for packaging purposes, including as sausage casings, because of their impermeability to water vapor and air. So a tubular film made of nylon 12 is used as the sausage casing.
Es ist auch bekannt, Mehrschichtfolien als Wursthüllen zu verwenden, z.B. einen mit einem wasserdampfundurchlässigen Polymeren beschichteten Zellglasschlauch. Solche Mehrschichthüllen werden in der Regel durch Imprägnieren oder Beschichten Giner Einschichtschlauchfolie hergestellt.It is also known to use multilayer films as sausage casings, e.g. a cellular glass tube coated with a polymer impermeable to water vapor. Such multilayer casings are usually made by impregnating or coating giner single-layer tubular film.
Es ist weiter bekannt, Mehrschichtverbundfolien aus verschiedenen thermoplastischen Materialien durch Verbundstrangpressen herzustellen. Diese Herstellung ist aber auf relativ engIt is also known to extrude multilayer composite films made of various thermoplastic materials by composite extrusion to manufacture. This production is relatively tight
mit einander verwandten Materialien beschränkt, da sonst keine ausreichende Haftung zwischen den einzelnen Schichten aus verschiedenen Materialien erzielt wird. Man muß hier häufig einen Primer verwenden, um ein festes Verkleben der Verbundschichten zu erzielen.limited with related materials, otherwise there will be insufficient adhesion between the individual layers different materials is achieved. A primer must often be used here in order to ensure that the composite layers are firmly bonded to achieve.
Die bisher bekannten Wursthüllen aus Polyamid bestehen aus dem verhältnismäßig teueren Nylon 12 oder Nylon 11, da nur diese sehr reinen Polyamide lebensmittelrechtlich unbedenklich sind und keine oder nur sehr wenige schädliche Bestandteile, wie Monomeren usw. enthalten, die aus der Hülle heraus in das Lebensmittelgut gelangen können.The previously known sausage casings made of polyamide consist of the relatively expensive nylon 12 or nylon 11, as only these very pure polyamides are harmless in terms of food law and have no or only very few harmful components, such as monomers, etc., which can get out of the casing into the food.
Es wäre nun erwünscht, wenigstens einen Teil des teuren Nylon 12 durch ein billigeres Material zu ersetzen.It would now be desirable to replace at least some of the expensive nylon 12 with a cheaper material.
Dies gelingt erfindungsgemäß mittels einer Mehrschicht-Verbundfolie, vorzugsweise einer Zweischichtfolle aus thermoplastischen Kunststoffen, deren Schichten aus einander ähnlichen Thermoplasten bestehen, wobei eine Schicht aus einem vergleichsweise billigen Thermoplasten besteht. Als Thermoplasten werden Polyamide bevorzugt. Eine besonders bevorzugte Ausführungsform besteht aus einer Zweischichtfolie, deren Schichten aus zwei verschiedenen Polyamiden bestehen, wobei die innere, dem Wurstgut zugewandte Schicht aus Nylon 12 oder Nylon 11 und die Außenschicht vorzugsweise aus dem vergleichsweise billigen Nylon 6 besteht.This is achieved according to the invention by means of a multilayer composite film, preferably a two-layer film made of thermoplastics, the layers of which are similar to one another Thermoplastics consist, with one layer consisting of a comparatively cheap thermoplastic. As thermoplastics polyamides are preferred. A particularly preferred embodiment consists of a two-layer film whose Layers consist of two different polyamides, the inner layer facing the sausage being made of nylon 12 or Nylon 11 and the outer layer is preferably made of the comparatively cheap nylon 6.
Die Dickenverhältnisse einer solchen Verbundfolie können je nach Kaliber der zu verpackenden Wurst schwanken; als Beispiel sei eine Stärke der Innenschicht aus Nylon 12 oder Nylon 11 von ca. 20 JU und eine Stärke der Außenschioht von Nylon 6 η oder anderen geeigneten Thermoplasten von ca. 25 bis 50 M ge-The thickness ratios of such a composite film can vary depending on the caliber of the sausage to be packaged; As an example, a thickness of the inner layer made of nylon 12 or nylon 11 of approx. 20 JU and a thickness of the outer layer of nylon 6 η or other suitable thermoplastics of approx. 25 to 50 M

Die erfindungsgemäße Wursthülle hat weiter den Vorteil der besseren Verarbeltbarkeit. Da Nylon 6 in Wasser quillt, erhält die Wursthülle einen weicheren Griff. Nylon 6 und Nylon 12 ergänzen sich vorteilhaft weiter dadurch, daß aufgrund der geringerem Quellung von Nylon 12 die Innenschicht die Formstabilität der Hülle gewährleistet.The sausage casing according to the invention also has the advantage that it can be processed better. Since nylon 6 swells in water, the sausage casing has a softer feel. Nylon 6 and nylon 12 advantageously complement each other in that, due to the lower swelling of nylon 12, the inner layer ensures the dimensional stability of the shell.
Als weiterer überraschender Vorteil zeigt sich, daß die erfindungsgemäße Wursthülle eine geringere Durchlässigkeit für Sauerstoff als eine Nylon 12 -Einschichthülle hat.Another surprising advantage is that the sausage casing according to the invention has a lower permeability for Oxygen as a nylon 12 monolayer shell.
Die Herstellung der erfindungsgemäßen Wursthülle erfolgt auf an sich bekannt Welse. Die erfindmgsgemäß besonders bevorzugte ZweischichthülIe aus Nylon 12/N;/lon 6 wird bei ca. 2200C nach dem Blasextrudierverfahren mit geeigneten konzentrischen Extruderköpfen hergestellt.The sausage casing according to the invention is produced using catfish known per se. The erfindmgsgemäß particularly preferred ZweischichthülIe of nylon 12 / N; / lon 6 is prepared at about 220 0 C after Blasextrudierverfahren with appropriate concentric extruder heads.
Der erfindungsgemäßen Wursthülle kann überraschenderweise mittels geeigneter Maßnahmen eine gewisse Elastizität verliehen werden, die bewirkt, daß sich die Hülle auch nach dem Schrumpfen des Wurstguts beim Kochen bzw. Brühen fest an dieses anlegt, so daß die Wurst immer ein pralles und damit ansehnliches Aussehen hat.The sausage casing according to the invention can surprisingly be given a certain elasticity by means of suitable measures be, which causes the shell after the Shrinkage of the sausage product during cooking or scalding is firmly attached to this, so that the sausage always has a plump and therefore attractive appearance.
In der anliegenden Figur ist eine aufgeschnittene zweisohichti-. ge Wursthülle dargestellt. Folie I ist die dem Wurstgut zugewandte innere, Folie II die äußere Schicht.In the attached figure is a cut open two-layered. ge sausage casing shown. Foil I is the inner layer facing the sausage product, foil II the outer layer.
