Abstract
Description
Die vorliegende Erfindung betrifft eine Kunststoff-Folie zur Verpackung von Lebensmitteln, zur Herstellung von Beuteln, insbesondere von Gefrierbeuteln, oder dergleichen.The The present invention relates to a plastic film for packaging of food, for the manufacture of bags, in particular of Freezer bags, or the like.
Kunststoff-Folien der vorerwähnten Art werden überwiegend im Haushalt verwendet und deshalb marktüblich auch als Haushaltsfolien bezeichnet.Plastic films the aforesaid Style become prevalent used in the household and therefore commercially available as household films designated.
Dabei werden derartige Kunststoff-Folien als Einwickelmaterial für Lebensmittel verwendet oder zu Beuteln oder Gefrierbeuteln oder dergleichen verarbeitet, um Lebensmittel darin zu verpacken. Sofern Kunststoff-Folien zum Einwickeln von Lebensmitteln benutzt werden, sind diese handelsüblich zu Rollen aufgewickelt, von denen je nach Bedarf entsprechende Längen abgetrennt werden.there Such plastic films are used as wrapping material for food used or processed into bags or freezer bags or the like, to pack food in it. If plastic foils for Wrapping food are used, these are commercially available too Rolls wound, of which corresponding lengths separated as needed become.
In allen Fällen sind Kunststoff-Folien für die genannten Anwendungszwecke bislang mit dem Nachteil behaftet, dass deren Oberflächen sehr starke Adhäsionskräfte aufweisen, so dass die Handhabung sowohl einer zu einer Rolle aufgewickelten Kunststoff-Folie wie auch eines aus Kunststoff-Folie hergestellten Beutels oder dergleichen in der Praxis problematisch ist, da sowohl aufeinander liegende Flächen einer Kunststoff-Folie wie auch an einem zu verpackenden Gut anliegende Oberflächen einer Kunststoff-Folie oder eines daraus hergestellten Beutels sehr stark an dem verpackten Gut anhaften.In all cases are plastic films for the applications mentioned so far have the disadvantage that that their surfaces have very strong adhesion forces, so that the handling of both wound into a roll plastic film as well as a bag made of plastic film or the like is problematic in practice, since both superposed surfaces of a Plastic film as well as fitting to a good to be packaged surfaces a plastic film or bag made from it very much strongly attached to the packaged goods.
Bei aus Kunststoff-Folien hergestellten Beuteln oder Gefrierbeuteln kann dies dazu führen, dass der Beutel bei der Entnahme des verpackten Gutes an Stellen sehr hoher Haftung zwischen Beutelwand und verpackten Gut zerstört wird und diese Bereiche am verpackten Gut haften bleiben. Gleiches gilt in ähnlicher Form bei der Verwendung von Kunststoff-Folien zum Einwickeln von Lebensmitteln.at Bags made of plastic films or freezer bags can this cause that the bag when removing the packaged goods in places very high adhesion between bag wall and packaged goods is destroyed and these areas stick to the packaged goods. same for in a similar way Mold when using plastic films for wrapping Food.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Kunststoff-Folie der gattungsgemäßen Art zu schaffen, die die geschilderten Nachteile nicht mehr aufweist, das heißt, eine Kunststoff-Folie zu schaffen, die aufgrund erheblich geringerer Oberflächenhaftfähigkeit deutlich besser handhabbar ist.Of the present invention is based on the object, a plastic film of the generic type to create, which no longer has the described disadvantages, this means, to create a plastic film due to significantly lesser Surface adhesion much easier to handle.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass zumindest eine Oberfläche der Kunststoff-Folie mit einer Antihaftbeschichtung versehen ist.These Task is inventively characterized solved, that at least one surface the plastic film is provided with a non-stick coating.
Durch diese Maßnahme wird die unerwünschte Eigenschaft des Anhaftens von auf einander liegenden Bereichen einer Kunststoff-Folie ebenso deutlich herabgesetzt wie das unerwünschte Anhaften an einem mittels einer derartigen Kunststoff-Folie zu verpackenden Gut.By This measure becomes the unwanted Property of adhering to one another areas of a Plastic film as significantly reduced as the unwanted adhesion to be packed by means of such a plastic film Well.
Vorraussetzung hierfür ist selbstverständlich, dass das zu verpackende Gut bei einer nur einseitig mit einer Antihaftbeschichtung versehenen Kunststoff-Folie mit dieser entsprechenden Oberfläche in Kontakt gebracht wird. Bei einer Kunststoff-Folie zum Einwickeln eines zu verpackenden Lebensmittels sollte in diesem Falle die antihaftbeschichtete Oberfläche optisch kenntlich gemacht werden und bei der Verwendung einer derartigen Kunststoff-Folie als Beutel oder Gefrierbeutel sollte diese antihaftbeschichtete Oberfläche die Innenseiten des Beutels bilden.requirement therefor is obvious that the product to be packaged with only one side with a non-stick coating provided plastic film with this corresponding surface in contact is brought. In a plastic film for wrapping a to be packaged Food should in this case the non-stick surface visually be identified and in the use of such Plastic film as a bag or freezer bag should be non-stick coated surface form the insides of the bag.
Sofern beide Oberflächen mit einer Antihaftbeschichtung versehen sind, wären die vorstehend genannten Kriterien nicht mehr zu beachten.Provided both surfaces provided with a non-stick coating, would be the above No longer observe the criteria.
Die Antihaftbeschichtung kann aus Teflon, aus Silikon oder aus einem Gemisch aus Teflon und Silikon bestehen.The Non-stick coating can be made of Teflon, silicone or one Mixture of Teflon and silicone exist.
Die Antihaftbeschichtung kann auf die Kunststoff-Folie aufgesprüht sein, es besteht darüber hinaus die Möglichkeit, eine Antihaftbeschichtung auf die Kunststoff-Folie aufzudrucken oder im Coextrusionsverfahren auf eine Kunststoff-Folie aufzubringen. Hierdurch ist sowohl eine einseitige wie auch beidseitige Beschichtung einer Kunststoff-Folie mit einer Antihaftbeschichtung möglich.The Non-stick coating can be sprayed on the plastic film, it exists about it addition the possibility to print a non-stick coating on the plastic foil or applied by coextrusion on a plastic film. hereby is both a one-sided as well as two-sided coating one Plastic film with a non-stick coating possible.
Die Antihaftbeschichtung kann alternativ auch im Tauchverfahren auf eine Kunststoff-Folie aufgebracht werden, wobei hier dann in jedem Falle beide Oberflächen der Kunststoff-Folie mit einer Antihaftbeschichtung versehen werden.The Non-stick coating can also be used in the dipping process a plastic film are applied, in which case then in each Trap both surfaces the plastic film to be provided with a non-stick coating.
Ein Ausführungsbeispiel der Erfindung ist in der beigefügten Zeichnung dargestellt und wird im folgenden näher beschrieben.One embodiment the invention is in the attached Drawing shown and will be described in more detail below.
Die einzige Figur zeigt einen stark vergrößerten Teilquerschnitt durch eine Kunststoff-Folie gemäß vorliegender Erfindung.The single figure shows a greatly enlarged partial cross section a plastic film according to the present Invention.

Diese Antihaftbeschichtung kann aus Teflon, aus Silikon oder einem Gemisch aus Teflon und Silikon bestehen.This non-stick coating can be made of teflon, Made of silicone or a mixture of Teflon and silicone.
Selbstverständlich sind auch weitere, geeignete Materialien zur Reduzierung der Adhäsionskräfte denkbar.Of course they are Also, other suitable materials for reducing the adhesion forces conceivable.
Eine bevorzugte Ausführungsform der Erfindung besteht darin, dass die Antihaftbeschichtung aus einem Pfropfpolymer und einem Pfropfcopolymer besteht. Eine derart beschichtete Kunststoff-Folie lässt sich ohne weiteres thermisch behandeln, insbesondere kann eine derart beschichtete Kunststoff-Folie problemlos verschweißt werden.A preferred embodiment The invention consists in that the non-stick coating of a Graft polymer and a graft copolymer. Such a coated Plastic foil leaves can easily be treated thermally, in particular, such a coated plastic film can be welded easily.
