In der Technik sind zum korrosionsgeschützten Verpacken metall- i haltiger Gegenstände flexible Verpackungen in Form von Korro- f

VCI-Papiere (Volatile Corrosion Inhibitor). Diese glatten oder I

imprägniert. Die aufgebrachten Korrosionsschutzstoffe verdunsten und bilden auf den zu schützenden Metallen einen dünnen ?

These are the so-called VCI papers (Volatile Corrosion Inhibitor). These smooth or creped papers are coated or impregnated with active substances. The applied anti-corrosive substances evaporate and form a thin film on the metals to be protected. At the same time, the active substance is also released into the surrounding air, so that an additional vapor barrier may be required to reduce the concentration of the VCI active substance.
to preserve the goods to be protected. This additional vapour barrier can be made with heat-sealable polyolefin films or
preferably with aluminum composite foil, depending on the desired storage period. ;

Es ist auch bekannt/ VCI-Papier einseitig mit einer Dampfsperre zu käsötiieren. Derartige Kombinat ionen können jedoch nur als Einwickler Anwendung finden, daIt is also known to coat VCI paper with a vapor barrier on one side. However, such combinations can only be used as wrappers, since

Papier nur direkt zum Metall die Schutzwirkung entfalten kann.Paper can only exert a protective effect directly on the metal.
Der Neuerung liegt die Aufgabe zugrunde, flexible Verpackungen bereitzustellen, mit denen korrosionsgefährdete, Metall aufweisende Gegenstände nicht nur eingewickelt werden können, sondern vielmehr auch die korrosionsfordernde, wasserdampfhaltige Luft und andere korrodierende Gase weitgehend von der Einwirkung auf den Metall aufweisenden Gegenstand abgehalten werden und sich die flexible Verpackung möglichst eng an den zu umhüllenden Metallgegenstand anschmiegt.The innovation is based on the task of providing flexible packaging with which metal objects that are at risk of corrosion can not only be wrapped, but also the corrosion-promoting air containing water vapor and other corrosive gases are largely prevented from affecting the metal object and the flexible packaging fits as closely as possible to the metal object to be wrapped.
Neuerungsgemäß wird die Aufgabe durch die kennzeichnenden Merkmale des Schutzanspruchs 1 gelöst*According to the innovation, the problem is solved by the characterizing features of claim 1*
Mit Hilfe dieser Neuerung ist es möglich, die für die Einwicklung verwendeten Verschlüsse und die zum Verpacken üblichen nutzlosen Einschlagungen einzusparen und gleichzeitig den Metall aufweisenden GegenstandThis innovation makes it possible to eliminate the fasteners used for wrapping and the useless wrappings that are usually used for packaging, while at the same time protecting the metal object
noch besser vor den ihn umgebenden korrosionsfördernden Gasen zu schützen, indem man die flexible Verpackung selbsthaftend am Metallgegenstand befestigt.to provide even better protection against the corrosive gases surrounding it by attaching the flexible packaging self-adhesively to the metal object.

Andererseits kann die Trägerschicht auch aus Polyolefinen oder sonstigen Kunststoffolien bestehen, die ein- oder beidseitig klebend mit dem Korrosionsschutzstoff, der sich in der Klebstoffschicht befindet, beschichtet werden.«coated or impregnated on one or both sides»* The anti-corrosive substance is integrated into the adhesive material. On the other hand, the carrier layer can also consist of polyolefins or other plastic films that are coated on one or both sides with the anti-corrosive substance that is in the adhesive layer.
Sollen die Metall aufweisenden Gegenstände neben dem Korrosionsschütz auch noch abgepolstert werden, so können anstelle der Kunststoffolien Schaumstoffe aus polymerisierten Kunststoffen, Gummischaum oder Luftpolsterfolien, Vliese usw., die jeweils gegebenenfalls mit Gewebe oder Fadengelege verstärkt sind, mit dem Korrosionsschutzstoff im Klebstoffmaterial ein- oder zweiseitig beschichtet werden.If the metal objects are to be padded in addition to the corrosion protection, foams made of polymerized plastics, rubber foam or bubble wrap, fleece, etc., which may be reinforced with fabric or thread, can be coated on one or both sides with the corrosion protection substance in the adhesive material instead of the plastic films.
Verwendet man siegelfähige Polyolefine, z.B. PoIyethylenfolien, so können diese nach der Behandlung zusätzlich heiß verschweißt werden, um so eine wasserdampf dichte Verpackung zu erhalten. In gleicher Weise können auch Zwei- oder Mehrfachverbundfolxen wie PETP-PE, PA-PE oder Alu-Verbundfolien oder Kombinationen hieraus verwendet werden.If sealable polyolefins are used, e.g. polyethylene films, these can be additionally heat-sealed after treatment in order to obtain a water vapor-tight packaging. In the same way, two or multiple composite films such as PETP-PE, PA-PE or aluminum composite films or combinations thereof can be used.
Weiterhin ist es auch möglich, flexible Verpackungen, wie sie aus dem Stand der Technik bekannt sind, nachträglich mit einer Mischung aus dem Korrosionsschutzstoff und dem Klebstoff material zu beschichten bzw. zu imprägnieren.Furthermore, it is also possible to subsequently coat or impregnate flexible packaging, as is known from the state of the art, with a mixture of the corrosion protection substance and the adhesive material.

Als selbstklebende Substanzen können Latex, Acrylate, Mikrowachse sowie alle dauernd plastisch bleibenden Haftkleber verwendet werden.Latex, acrylates, micro waxes and all adhesives that remain permanently plastic can be used as self-adhesive substances.
Der chemische Korrosionsschutzstoff muß entsprechend modifiziert werden, damit die Einbringung in den Kleber in Wasser oder fettlöslicher Form öder mittels Lösungsmittel erfolgen kann.The chemical corrosion inhibitor must be modified accordingly so that it can be incorporated into the adhesive in water or fat-soluble form or by means of a solvent.
Als besonders geeignet haben sich die Korrosionsschutzstoffe erwiesen, die für die Rostschutzbekämpfung bei Eisen oder nichtrostfreien Eisenlegierungen verwendet werden können.The corrosion protection substances that can be used to combat rust on iron or non-rust-proof iron alloys have proven to be particularly suitable.

Here it does not matter which of the two sides faces the metal-containing object 12. The layer of adhesive material 14 on the opposite side of the carrier layer 10, which contains the corrosion protection substance 11, also acts as a vapor barrier, so that even in the case of small cracks in the carrier material, the corrosion protection substance 11 is not damaged.
