Abstract

Fibre-reinforced wrapping film comprises a self-crosslinking synthetic resin dispersion applied to a fibre carrier. The film may also contain barrier substances to control permeability to vapour and fumes. The resin dispersion is pref. a copolymerisate of vinyl acetate with ethylene or an acrylate or of butadiene with acrylonitrile or a formaldehyde-free copolymerisate of an acrylate with styrene and/or acrylonitrile. A copolymerisate of butyl acrylate with styrene and acrylonitrile is esp. preferred. Pref. a fleece or a woven or webbed natural fibre (e.g. cotton, linen, silk, cellulose or collagen) is pref. used, although a synthetic fibre (e.g. a polyamide, polyester or polypropylene) is also suitable. Pref. a pulverous pigment in an amt. of 0.5-15 wt.% can be used for this purpose. Suitable pigments include metals (e.g. aluminium and bronze) and water-insol. metal oxides and metal salts (e.g. CaCO3, BaSO4 and TiO2. USE/ADVANTAGE - The film is pref. used to wrap foodstuffs, esp. sausage (wurst) and cheese. The film has good tensile strength and stretches well, is stable to hot water and solvents and, in wurst prodn., is not affected by fats, emulsifiers and salts. Further, when disposed of in refuse, the film degrades without harming the environment.

Description

Die Erfindung betrifft faserverstärkte Folien nach dem Ober­ begriff des Anspruchs 1.The invention relates to fiber-reinforced films according to the upper Concept of claim 1.

Es ist bekannt, beschichtete Träger als Hüllen für Lebens­ mittel und ähnliches zu verwenden. Als Beschichtungsmittel werden die unterschiedlichsten Kunstharzemulsionen oder -dispersionen verwandt. Bei der Auswahl der Kunstharze steht dabei eine gewünschte Wasserdampf und Rauchdurchläs­ sigkeit der durch die Beschichtung einer Verstärkung aus Fa­ serstoffen erhaltenen Folie im Vordergrund.It is known to use coated carriers as casings for life to use medium and the like. As a coating agent are the most diverse synthetic resin emulsions or -dispersions related. When choosing synthetic resins there is a desired water vapor and smoke passage liquid by coating a reinforcement from in the foreground.

Der immer größere Anfall von Abfallstoffen und die anlau­ fende Abfallbeseitigung durch Kompostierung machen es wei­ ter notwendig, für die Umhüllungen in der Lebensmittelindu­ strie möglichst verrottbare Faserstoffe und Kunstharze für die Beschichtung einzusetzen, die die Umwelt nicht bela­ sten.The increasing amount of waste and the anlau Effective waste disposal through composting make it white ter necessary for the wrappings in the food indu strayed rotten fibers and synthetic resins for to use the coating that does not pollute the environment most.

Der Erfindung liegt die Aufgabe zugrunde, Kunstharze für die Beschichtung von Trägern zur Herstellung von Folien zu finden, die die Umwelt nicht belasten eine Steuerung der Wasserdampf und Rauchgasdurchlässigkeit durch Zusätze erlauben aber dabei die anderen gewünschten Eigenschaften der bisher für den Beschichtungsvorgang eingesetzten Kunst­ harze ebenfalls aufweisen.The invention has for its object synthetic resins for the coating of supports for the production of films find those that do not pollute a control of the environment Water vapor and smoke permeability through additives but allow the other desired properties the art previously used for the coating process also have resins.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die Kunstharze für die Beschichtungen selbstvernetzende Kunst­ harzdispersionen sind, die Zusätze mit einer Barrierewirkung gegenüber Wasserdampf und Rauchgase enthalten können.According to the invention the object is achieved in that the Synthetic resins for the coatings self-crosslinking art Resin dispersions are the additives with a barrier effect against water vapor and flue gases.

Als selbstvernetzende Kunstharzdispersionen werden Copolye­ risate des Vinylacetats mit Ethylen oder Acrylsäureestern, formaldehydfreie Copolymerisate von Acrylsäureestern mit anderen polymerisierbaren Verbindungen, wie Styrol und/oder Acrylnitril aber auch Copolyinerisate aus Butadien und Acryl­ nitril eingesetzt.Copolyes are used as self-crosslinking synthetic resin dispersions risks of vinyl acetate with ethylene or acrylic acid esters, formaldehyde-free copolymers of acrylic acid esters with other polymerizable compounds, such as styrene and / or Acrylonitrile but also copolyinerisate from butadiene and acrylic nitrile used.

Sehr gut läßt sich z. B. ein Copolymerisat aus Acrylsäurebu­ tylester, Styrol und Acrylnitril verwenden.Z. B. a copolymer of acrylic acid Use tylester, styrene and acrylonitrile.

Als eine Barrierewirkung gegenüber Wasserdampf und Rauchga­ se aufweisende Materialien werden erfindungsgemäß wasserun­ lösliche lebensmittelrechtlich unbedenkliche feinkörnige Pigmente eingesetzt. Die Pigmente werden in Mengen von 0,5 bis 15 Gew% der Kunstharzdispersion vor dem Auftragen auf den Beschichtungsträger zugesetzt.As a barrier to water vapor and smoke gas According to the invention, materials containing water are water-resistant soluble fine-grained food-safe Pigments used. The pigments are used in amounts of 0.5 up to 15% by weight of the synthetic resin dispersion before application added to the coating medium.

Als Pigmente kommen Metalle, z. B. Aluminium, Bronzen aber auch Metalloxide oder wasserunlösliche Metallsalze, wie feindisperse Kieselsäuren, Calciumcarbonat, Bariumsulfat, Titandioxid in Frage. Je nach zugesetzter Menge kann die Durchlässigkeit gegenüber Wasserdampf und Rauchgasen gesteu­ ert werden.As pigments come metals, e.g. B. aluminum, but bronzes also metal oxides or water-insoluble metal salts, such as finely dispersed silicas, calcium carbonate, barium sulfate,  Titanium dioxide in question. Depending on the amount added, the Permeability to water vapor and smoke gases controlled be recognized.

Die für die Beschichtung eingesetzten Dispersionen der Copo­ lymerisate weisen einen Festkörpergehalt von vierzig bis fünfundfünfzig Gew.% bei einer Teilchengröße von 0,1 bis 0,3 µm auf. Der pH-Wert der Dispersionen kann zwi­ schen 1,5 bis 8,5 schwanken, der für eine gute Vernetzung der Dispersionen sorgt. Sollte dieser pH-Wert für die Ver­ netzung nicht ausreichend sein, so kann die Vernetzung durch Zugabe einer geringen Menge an Katalysatoren, wie Mal­ einsäure, Oxalsäure, Phosphorsäure bzw. deren Ammoniumsalze oder Ammoniumnitrat zur Dispersion verbessert werden.The Copo dispersions used for the coating Lymerisate have a solids content of forty to fifty-five weight percent with a particle size of 0.1 to 0.3 µm. The pH of the dispersions can be between fluctuate between 1.5 and 8.5, for good networking of the dispersions. Should this pH value for ver networking may not be sufficient, networking can by adding a small amount of catalysts such as Mal Acid, oxalic acid, phosphoric acid or their ammonium salts or ammonium nitrate can be improved for dispersion.

Als Beschichtungsträger wird ein flächenhafter, aus natür­ lichen oder regenerierten Fasern aber auch aus Kunstharzfa­ sern bestehendes Gebilde eingesetzt. Bei den Kunstharzfa­ sern ist beispielsweise an solche aus Polyamid, Polyester, Polypropylen u.ä. gedacht. Das flächenhafte Gebilde besteht aus einem Vlies, Gewirke oder Gewebe. Für die gewebten oder ungewebten Flächengebilde werden vorzugsweise Naturfasern, modifizierte Naturfasern, wie Baumwolle, Leinen, Seide, Zellulose oder Kollagen verwandt.As a coating carrier, a flat, natural Lichen or regenerated fibers but also made of synthetic resin existing structure used. With the synthetic resin fa sern is, for example, those made of polyamide, polyester, Polypropylene and the like thought. The flat structure exists from a fleece, knitted or woven fabric. For the woven or non-woven fabrics are preferably natural fibers, modified natural fibers such as cotton, linen, silk, Cellulose or collagen related.

Die Beschichtung der Beschichtungsträger mit den Dipersi­ onen kann im Direktstreichverfahren oder Umkehrverfahren vorgenommen werden.The coating of the coating carrier with the Dipersi onen can be by direct or reverse process be made.

Beim Direktstreichverfahren wird die Kunstharzdispersion als Paste oder Schaum auf den Träger aufgebracht und ge­ trocknet. Dabei kann der Träger vorher in einen Spannrahmen eingespannt werden, oder er wird lose auf ein Tragbandtrock­ ner, auf einen Schwebtrockner oder einen Trockner mit Unter­ stützungswalzen aufgebracht. In the direct coating process, the synthetic resin dispersion applied to the carrier as a paste or foam and ge dries. The carrier can be placed in a stenter beforehand can be clamped, or it will be loosely on a carrier belt ner, on a float dryer or a dryer with sub support rollers applied.  

Der auf dem Beschichtungsträger entstehende Film oder ge­ trocknete Schaum wird zur Vernetzung auf über 130°C erhitzt und dabei zur Vergleichmäßigung der Filmstärke kalandriert.The film on the coating carrier or ge Dried foam is heated to over 130 ° C for crosslinking and calendered to even out the film thickness.

Beim Umkehrverfahren wird die Kunstharzdispersion auf ein Endlosträgerband aus Metall, Teflon oder Silikonkautschuk aufgebracht. In die Dispersion wird dann der Beschichtungs­ träger eingedrückt und das so erhaltene Gebilde getrocknet. Der mit der Kunstharzdispersion versehene Träger kann jetzt sofort im In-line-Verfahren vernetzt werden.In the reverse process, the synthetic resin dispersion is reduced to one Endless carrier tape made of metal, Teflon or silicone rubber upset. The coating is then added to the dispersion pressed in carrier and dried the structure thus obtained. The carrier provided with the synthetic resin dispersion can now can be networked immediately using the in-line process.

Bei einer anderen Variante wird die Vernetzung in einem se­ paraten Arbeitsgang vorgenommen.In another variant, the networking is in a se separate operation.

Das Umkehrverfahren ist besonders für solche Beschichtungs­ träger von Vorteil, die im Direktstreich- oder Schaumauf­ tragverfahren nicht beschichtet werden können.The reverse process is especially for such coating Advantageous carriers in direct spread or foam application can not be coated.

Bei allen Verfahren kann die Dispersion ein- oder mehrmalig aufgetragen werden.In all processes, the dispersion can be applied one or more times be applied.

Der erhaltene beschichtete Träger, also die Folie, ist stabil gegenüber heißem Wasser und Lösungsmitteln.The coated support obtained, ie the film, is stable against hot water and solvents.

Werden die Folien als Umhüllungen bei der Wurstherstellung eingesetzt, so zeigen sie sich stabil gegenüber den bei der Wurstherstellung eingesetzten Agenzien, wie Fette, Emul­ gatoren oder Salze Zusätzlich können die Dispersionen pigmentiert werden, so daß Folien mit beliebiger Einfärbung erzielbar sind. Die Pigmentierung kann natürlich mit der Barrierewirkung gegen­ über Wasserdampf und Rauchgas gekoppelt werden. Bei der Verwendung der Folie für Nahrungsmittelhüllen ist auch der Zusatz von natürlichen Gewürzen oder Gewürzstoffen möglich, um dem zu verpackenden Nahrungsmittel zusätzliche Geschmacksrichtungen zu verleihen. Die Haltbarkeit der Ver­ packungsfolien wird dabei nicht von den zugesetzten Gewür­ zen beeinträchtigt.The films are used as wrappings in sausage production used, they show themselves to be stable against the agents used in sausage production, such as fats, emul gators or salts In addition, the dispersions can be pigmented that films with any coloration can be achieved. The Pigmentation can of course counteract with the barrier effect be coupled via water vapor and flue gas. In the Use of the film for food casings is also the  Addition of natural spices or spice substances possible, to add additional to the food to be packaged To give flavors. The durability of ver Packing foils are not affected by the added spices zen impaired.

Die Folien zeigen eine gute Reißfestigkeit und Reißdehnung.The films show good tensile strength and elongation at break.

Eine Eigenschaft dieser erhaltenen faserverstärkten Folien ist , daß der Beschichtungsträger weitgehend verrottet und teilweise auch der Kunstharzfilm von Bakterien angegriffen wird.A property of these fiber-reinforced films obtained is that the coating carrier largely rots and some also attack the synthetic resin film from bacteria becomes.
