Description
Aluminium-Mehrfachfolie.
Ihrerseits sind Lacküberzüge mechanisch so wenig widerstandsfähig, dass sie nicht standhalten, wenn die Aluminiumfolie reißt.For their part, lacquer coatings are mechanically so poorly resistant, that they won't withstand if the aluminum foil tears.
Ferner ist eine Doppelfolie bekannt, die aus zwei Metallfolien besteht, welche mit Hilfe einer zähen, schmiegsamen und wasserfesten Zwischenschicht aus Guttapercha, Kautschuk oder dergleichen vereinigt sind. Diese Doppelfolie ist vollkommen luft-, wasserdampf-und wasserdicht, zudem zäh und schmiegsam. Aus ihr kann man mit Leichtigkeit Packungen herstellen, welche beispielsweise dem Füllgut das Aroma und die Feuchtigkeit erhalten. Ein Nachteil besteht jedoch darin, dass bei starker mechanischer Beanspruchung des Verpackungsmaterials sowohl die Vetallfolien als auch die Zwischenschicht aus Guttapercha unddergleichen reis sen, worauf der Schutz des Füllgutes nicht mehr gewährleistet ist. Furthermore, a double foil is known, which consists of two metal foils, which are made with the help of a tough, pliable and waterproof intermediate layer Gutta-percha, rubber or the like are combined. This double foil is perfect air, water vapor and waterproof, also tough and pliable. You can come out of it Easily produce packs which, for example, add the aroma and flavor to the contents maintain the moisture. A disadvantage, however, is that with strong mechanical Stress on the packaging material, both the metal foils and the intermediate layer from gutta-percha and the like, whereupon the protection of the contents no longer occurs is guaranteed.
Die Neuerung bezieht sich nun auf eine Mehrfachfolie, die aus mindestens zwei Aluminiumfolien besteht, welche mit Hilfe einer Mischung von Polyaethylen und Polyisobutylen verbunden sind, zwecmäsigerweise in einem Mischungsverhältnis Polyaethylen zu Polyisobutylen von mindestens 50:50 und höchstens 70130. The innovation now relates to a multiple film that consists of at least consists of two aluminum foils, which are made with the help of a mixture of polyethylene and Polyisobutylene are connected, zwecmäsigerweise in a mixing ratio of polyethylene to polyisobutylene of at least 50:50 and at most 70130.
Auf der Aluminium-Mehrfachfolie gemäss der Neuerung kann ausserdem
auf der einen Seite oder auf beiden Seiten eine heirssiegelfähige Kunststoffschicht
aus Polyaethylen und Polyisobutylen
aufgerbracht sein, .
Die Lösung wird vorzugsweise im Anschwemmverfahren aufgebracht, die zweite Folie am besten aufgewalzt.The solution is preferably applied using the precoating method second film is best rolled on.
Das Aufbringen der Kunststofflösung und einer Aluminiumfolie kann selbstverständlich wiederholt werden, sodas eine Verbundfolie mit drei oder mehr Aluminiumfolien entsteht. Man kann selbstverständlich auch eine Aluminiumfolie auf beiden Seiten gleichzeitig mit einer Kunststofflösung versehen und nach Trocknung ein-oder beidseitig Aluminiumfolien aufwalzen. Es sind auch andere Kombinationen denkbar. Wesentlich iat das Vorhandensein von zwei mit Hilfe einer KunststoffmischungdergenanntenZusammensetzungzusammengelkebten Aluminiumfolien. Applying the plastic solution and an aluminum foil can of course, are repeated so that a composite sheet with three or more Aluminum foils are created. You can of course also use an aluminum foil Apply a plastic solution to both sides at the same time and after drying Roll aluminum foils on one or both sides. There are other combinations as well conceivable. What is essential is the presence of two glued together with the aid of a plastic mixture of the composition mentioned Aluminum foils.
Durch Aenderung des Mischungsverhältnissen zwischen polyaethylen
und Po3 butylen hat mm es in der Hand, die Eigenschaften der Kunststoffzwischenschicht
weitgehend zu ändern. wobei die hohe Reißfestigkeit stete erhalten bleibt. Will
Schutzanaprüohe 1. Aluminium-Mehrfachfolie, dadurch gekennzeichnet, dass die aus mindestens zwei Aluminiumfolien besteht, die mit Hilfe einer Mischung von Polyaethylen und POlyisobutylen verbunden sind.Schutzanaprüohe 1st aluminum multiple film, characterized in that that the consists of at least two aluminum foils, which with the help of a mixture of polyethylene and polyisobutylene are connected.
