Abstract

A laminated foil for use as packaging material consists of one or more central plastic layers of PVC or other plastic materials which is lined on both sides with aluminium foil. The plastic foil has a thickness of 50-200 mu and the aluminium foil of 20-60 microns. At least one of the aluminium foils is coated with another biaxially stretched plastic foil of 10-40 mu thickness, such as oriented polypropylene, to improve the elongation. The outer layer can carry a lining of good hot sealing capacity. The foil is easy to sterilise and is more rigid for the same wall thickness. It is compatible with food and forms a good seal.

Description

Mehrschichtfolie i Multilayer film i

Die Erfindung betrifft eine Mehrschichtfolie mit Leicht metallschicht, insbesondere Aluminium, bekannt sind zur Herstellung von Formpackungen Folien mit einem Aufbau aus Leichtmetall, insbesondere Aluminium und Kunststoff. Diese haben jedoch den Nachteil, daß -- soweit die Kunststofffolie innen ist -- Unverträglichkeiten mit dem Füllgut auftreten können und daß diese Folie nicht sterilisierbeständig ist. Sofern sie auf der Außenseite aufgetragen ist ergeben sich Schwierigkeiten bei der Heißversiegelung.The invention relates to a multilayer film with a light metal layer, in particular aluminum, are known for the production of molded packs with foils a structure made of light metal, in particular aluminum and plastic. Have this however, the disadvantage that - as far as the plastic film is inside - incompatibilities can occur with the contents and that this film is not resistant to sterilization is. If it is applied on the outside, difficulties arise in the case of heat sealing.

Der Erfinder hat sich so zur Aufgabe gestellt, einen Folienaufbau zu entwickeln, der die Nachteile mangelnder Sterilisierbarkeit, beschränkter Heißsiegelfähigkeit, Diffusion ins Füllgut sowie unbefriedigende Steifigkeit beseitigt.The inventor has set himself the task of creating a film structure to develop the disadvantages of inadequate sterilizability, limited heat sealability, Diffusion into the product and unsatisfactory rigidity eliminated.

Die erfindungsgemäße Lösung der Aufgabe findet sich in Anspruch 1, sie besteht in der Verwendung einer beidseits beplankten PVC-Folie oder einer beidseitig beplankten Folie mit sonstigem Kunststoffkern, die zusätzlich noch mit StQtzfolien zur Dehnungsverbesserung ausgestattet werden kann. Hierzu nimmt man biaxial verstreckte Kunststoff-Folien, zum Beispiel orientiertes Polypropylen (GPp oder etnsprechend OPA).The inventive solution to the problem can be found in claim 1, it consists in the use of a PVC film planked on both sides or one on both sides Planked film with other plastic core, which is additionally still with StQtzfolien can be equipped to improve elongation. For this purpose, biaxially drawn ones are used Plastic films, for example oriented polypropylene (GPp or equivalent GRANDPA).

Die Erfindung bietet folgende Vorteile: Verwendbarkeit für jede Art von Füllgütern, größere Steifigkeit bei gleicher Materialdicke, Sterilisierbarkeit sowie unbeschränkte Heißsiegelfähigkeit.The invention offers the following advantages: Can be used for any species of filling goods, greater rigidity with the same material thickness, sterilizability as well as unlimited heat sealability.
