Description
Gegenstand der vorliegenden Erfindung ist ein Verpackungsmaterial für den Einsatz in Versandverpackungen, insbesondere als Schutz gegen Korrosion.The subject of the present invention is a packaging material for use in shipping packaging, in particular as protection against corrosion.
Im Stand der Technik werden für den Korrosionsschutz und die Exportverpackung insbesondere Aluminiumverbundfolien in verschiedenen Kombinationen eingesetzt.In the current state of the art, aluminum composite films in particular are used in various combinations for corrosion protection and export packaging.
Als Außenlage dienen üblicherweise Polyalkylenterephthalat-, Polyalkylen- oder Polyamid-Folie, -Gewebe oder -Vlies, Naturfaser-Gewebe oder -Vlies sowie Papier.Polyalkylene terephthalate, polyalkylene or polyamide film, fabric or fleece, natural fiber fabric or fleece and paper are usually used as the outer layer.
Die Verbundfolien werden als sogenannte Sperrschicht in Form von Beuteln oder Kisteneinsätzen gegen die Diffusion von Luftfeuchtigkeit benutzt.The composite films are used as a so-called barrier layer in the form of bags or box inserts to prevent the diffusion of air humidity.
Die so verpackten Güter müssen zusätzlich gegen Korrosion beispielsweise im Innern der Verpackung mittels Trockenmittel oder sonstigen Korrosionsschutz-Additiven enthaltenden Materialien (häufig als VCI Wirkstoffe bezeichnet, wobei VCI für „volatile corrosion inhibitor" steht) geschützt werden. Die Wirkstoffe können in verschiedenen Trägerbahnen, beispielsweise Papier, Schaumstoffe oder Kunststoff-Folien eingearbeitet werden.The goods packaged in this way must also be protected against corrosion, for example inside the packaging using desiccants or other materials containing corrosion protection additives (often referred to as VCI active ingredients, where VCI stands for "volatile corrosion inhibitor"). The active ingredients can be incorporated into various carrier materials, for example paper, foam or plastic films.

Es ist bekannt Papier oder andere Trägerbahnen mit den VCI-Wirkstoffen zu imprägnieren. Die Chemikalien werden aus einer wäßrigen Lösung oder organischen Lösungsmitteln wie beispielsweise Alkohol in die Papierbahn eingebracht. Das Wasser oder Lösungsmittel muß verdampft werden, so daß die Chemikalien in der Papierbahn oder der Trägerbahn zurückbleiben.It is known to impregnate paper or other carrier webs with the VCI active ingredients. The chemicals are introduced into the paper web from an aqueous solution or organic solvents such as alcohol. The water or solvent must be evaporated so that the chemicals remain in the paper web or the carrier web.
Da die Wirkstoffe teilweise wasserlöslich sind und bei einer starken Schwitzwasserbildung innerhalb einer Verpackung die Papierbahn oder andere Trägerbahnen sich mit Wasser vollsaugt, wird viel Wirkstoff gebunden. Die feuchte Papierbahn kann unter Umständen Korrosion erzeugen.Since the active ingredients are partially water-soluble and if there is a lot of condensation inside a package, the paper web or other carrier webs will absorb water, a lot of the active ingredient will be bound. The damp paper web can cause corrosion under certain circumstances.
Um diesen Nachteil teilweise zu verhindern, hat man im Stand der Technik die Papierbahn rückseitig mit einer Kunststoff-Folie wie beispielsweise PE, PP, oder mit Paraffinwachs beschichtet.In order to partially prevent this disadvantage, the state of the art has been to coat the back of the paper web with a plastic film such as PE, PP, or with paraffin wax.
Aufgabe der Erfindung ist die Bereitstellung einer preiswerten VCI-Wirkstoffe aufweisenden, wasserdichten Papier- oder Trägerbahn.The object of the invention is to provide an inexpensive, waterproof paper or carrier web containing VCI active ingredients.
Die vorgenannte Aufgabe wird in einer ersten Ausführungsform gelöst durch ein Verpackungsmaterial für den Einsatz in Versandverpackungen, insbesondere als Schutz gegen Wasserdurchgang mit einer Trägerbahn und wenigstens einer darauf aufgebrachten Schicht aus Paraffin oder Wachs, wobei die aufgebrachte Schicht Korrosionsschutz-Additive für Eisenmetalle und/oder Nichteisenmetalle enthält. Das Material ist hydrophob.The above-mentioned object is achieved in a first embodiment by a packaging material for use in shipping packaging, in particular as protection against water penetration with a carrier web and at least one layer of paraffin or wax applied thereto, wherein the applied layer contains corrosion protection additives for ferrous metals and/or non-ferrous metals. The material is hydrophobic.
Es wurde gefunden, daß sich die bekannten VCI-Wirkstoffe in Paraffin oder Wachs hervorragend gut einarbeiten lassen, wodurch eine homogene Masse erhalten wird. Der Anteil der VCI-Wirkstoffe kann dabei variabel auf den gewünschten Einsatzzweck abgestimmt werden. Die Herstellung der neuartigen Verpackungsmaterialien ist äußerst einfach und umweltfreundlich. So können beispielsweise die gewünschten Wirkstoffe in die Schmelze eingebracht werden. Nach dem Erstarren erhält man ein wirksames Korrosionsschutzmittel zurIt has been found that the known VCI active ingredients can be incorporated into paraffin or wax very well, resulting in a homogeneous mass. The proportion of VCI active ingredients can be varied to suit the desired application. The production of the new packaging materials is extremely simple and environmentally friendly. For example, the desired active ingredients can be introduced into the melt. After solidification, an effective corrosion inhibitor is obtained for
Imprägnierung oder Beschichtung von Trägerbahnen.Impregnation or coating of carrier webs.
Nicht nur die Herstellung, sondern auch die Anwendung dieser Korrosionsschutzmittel enthaltenden Massen aus Paraffin oder Wachs ebenso wie auch deren Anwendung zur Beschichtung von Trägerbahnen bringt erhebliche Vorteile in Bezug auf die Energieeinsparung, den Umweltschutz und die Fertigung von im Stand der Technik bekannten VCI-Papieren und sonstigen VCI-Produkten. Besonders bevorzugt im Sinne der vorliegenden Erfindung wird Papier als Trägerbahn eingesetzt.Not only the production, but also the use of these masses containing corrosion inhibitors made of paraffin or wax, as well as their use for coating carrier webs, brings considerable advantages in terms of energy savings, environmental protection and the production of VCI papers and other VCI products known in the prior art. Paper is particularly preferably used as the carrier web in the sense of the present invention.
Das Verfahren zur Herstellung der Verpackungsmaterialien kann dadurch realisiert werden, daß man die Korrosionsschutz-Additive in Wachs oder Paraffin einbringt und eine Schmelze auf die Trägerbahn einseitig oder beidseitig gleichzeitig oder nacheinander aufbringt. Die Dosierung kann mittels Walzen, Rakeln, Tränken oder Besprühen erfolgen. Im Anschluß an den Auftrag auf die Oberfläche der Trägerbahn folgt eine Abkühlung beispielsweise durch Kühlwalzen oder durch einen Luftstrom, wobei das Medium auf eine Temperatur unterhalb des Erstarrungspunktes gebracht wird.The process for producing the packaging materials can be implemented by adding the anti-corrosive additives to wax or paraffin and applying a melt to one or both sides of the carrier web simultaneously or one after the other. Dosing can be done by rolling, doctoring, soaking or spraying. After application to the surface of the carrier web, cooling follows, for example, using cooling rollers or an air stream, whereby the medium is brought to a temperature below the solidification point.
Zu Gewährleistung einer ausreichenden Wasserdichtigkeit sollte auch die Beschichtung eine Mindestdicke aufweisen, so daß es im Sinne der vorliegenden Erfindung bevorzugt ist, die Dicke der Beschichtung der Trägerbahn mit einem Flächengewicht von wenigstens 5 g/m2, insbesondere 20 g/m2 oder stärker, auszubilden.To ensure sufficient watertightness, the coating should also have a minimum thickness, so that in the sense of the present invention it is preferred to form the thickness of the coating of the carrier web with a basis weight of at least 5 g/m 2 , in particular 20 g/m 2 or more.
Besonders bevorzugt im Sinne der vorliegenden Erfindung sind die Korrosionsschutz-Additive ausgewählt aus Aminen, Aminoimidazolinen, Amino- und Nitrophenolen, Aminotriazolen, Morpholin, Phenylharnstoffderivaten, Aldehyden, Benzotriazol, Dibenzylsulfoxid, Dithiophosphonsäuren, Guanidinderivaten, Harnstoffen, Phosphoniumsalzen, Sulfoniumsalzen, Sulfonsäuren, Thioethern, Thioharnstoffen, Thiocarbamoyldisulfiden, Nitrite und Nitrate. Derartige Materialien sind im Stand der Technik als solche bekannt, werden hier jedoch erstmals in Form einer Beschichtung auf eine Trägerbahn für den Einsatz inParticularly preferred in the context of the present invention are the anti-corrosive additives selected from amines, aminoimidazolines, amino- and nitrophenols, aminotriazoles, morpholine, phenylurea derivatives, aldehydes, benzotriazole, dibenzyl sulfoxide, dithiophosphonic acids, guanidine derivatives, ureas, phosphonium salts, sulfonium salts, sulfonic acids, thioethers, thioureas, thiocarbamoyl disulfides, nitrites and nitrates. Such materials are known in the prior art as such, but are here for the first time in the form of a coating on a carrier web for use in
Versandverpackungen, insbesondere als Schutz gegen Wasserdurchgang eingesetzt.Shipping packaging, especially as protection against water penetration.
Da das erfindungsgemäße Verpackungsmaterial wasserdicht ist, kann sich die Trägerbahn, insbesondere die Papierbahn oder ein anderer Trägerstoff nicht mit Wasser vollsaugen, so daß Schwitzwasser abperlt. Die konstante Wirkstoffabgabe bleibt auch bei übermäßigem Schwitzwassereinbruch gewährleistet. Eine zusätzliche rückseitige wasserabweisende Kaschierung mit Beschichtungen wie Polyethylen, Polypropylen, Wachs oder ähnlichem ist nicht erforderlich. Fehler bei der Verwendung sind insbesondere dann ausgeschlossen, wenn beide Seiten der Trägerbahn beschichtet sind, da in diesem Fall beide Seiten wasserdicht sind. Erfindungsgemäß ergeben sich keine Probleme mit der Technischen Anleitung (TA-Luft) oder den maximalen Arbeitsplatzkonzentrationen (MAK-Werten), da vorzugsweise lösungsmittelfrei gearbeitet wird.Since the packaging material according to the invention is waterproof, the backing web, in particular the paper web or another carrier material, cannot soak up water, so that condensation water beads off. The constant release of active ingredients is guaranteed even if excessive condensation water enters. An additional water-repellent lamination on the back with coatings such as polyethylene, polypropylene, wax or similar is not necessary. Errors during use are particularly excluded if both sides of the backing web are coated, since in this case both sides are waterproof. According to the invention, there are no problems with the technical instructions (TA-Luft) or the maximum workplace concentrations (MAK values), since it is preferable to work without solvents.
Mit Hilfe der vorliegenden Erfindung ist somit eine problemlose Beschichtung oder Kaschierung in einem Arbeitsgang möglich, wobei die Trägerbahn beispielsweise aus gekreppten oder glatten Papierbahnen, aus Schaumstoff, beispielsweise aus Polyethylen oder Polyurethan, aus einem Zellulose- oder Kunststoffvlies, aus mit Gewebe kaschierten Papier oder Kunststoffbahnen oder aus sonstigen Kunststoff-Folien, wie Polyethylen, Polypropylen, Polyethylenterephthalat oder Aluminium bestehen kann.With the help of the present invention, a problem-free coating or lamination is thus possible in one operation, whereby the carrier web can consist, for example, of creped or smooth paper webs, of foam, for example of polyethylene or polyurethane, of a cellulose or plastic fleece, of paper or plastic webs laminated with fabric or of other plastic films, such as polyethylene, polypropylene, polyethylene terephthalate or aluminum.
Besonders bevorzugt werden die erfindungsgemäßen Verpackungsmaterialien zur Verpackung von Korrosions-gefährdeten Konsumgütern auf der Basis von Eisenmetallen und/oder Nichteisenmetallen eingesetzt.The packaging materials according to the invention are particularly preferably used for packaging consumer goods that are at risk of corrosion and are based on ferrous metals and/or non-ferrous metals.
Allgemein ist festzuhalten, daß die Menge an Korrosionsschutz-Additiv für Eisenmetalle und/oder Nichteisenmetalle der Beschichtung im Bereich von 5 bis 10 Gew.-%, insbesondere von 15 bis 20 Gew.-%, variiert werden kann.In general, it should be noted that the amount of corrosion protection additive for ferrous metals and/or non-ferrous metals in the coating can be varied in the range of 5 to 10 wt.%, in particular 15 to 20 wt.%.
Eine zu geringe Menge an Korrosionsschutemittel ergibt keine ausreichende Wirkung, während eine zu große Menge zum einen unwirtschaftlich ist und darüberToo little of a corrosion inhibitor does not produce sufficient effect, while too much is uneconomical and
hinaus die Qualitätseigenschaften des Verbundstoffes negativ beeinflußt.Furthermore, the quality properties of the composite are negatively affected.
