  • Heat-sealable composite materials for the production of packs, in particular beverage packs, are known in a wide variety of designs. Paper or cardboard is usually used as the carrier material; A lamination of different layers ensures the tightness required for the respective application and thus the durability of the filled product.
  • the outer sealing layers consist of a suitable thermoplastic polymer.
  • a composite of cardboard coated with polyethylene is preferably used, a layer of aluminum foil as a gas and aroma barrier on the inside (based on the later pack) being laminated to the cardboard carrier material with the sealing layer.
  • Packaging of this type has become established in practice for containing perishable goods, such as UHT milk and fruit juices in particular. The packaged product has already been sterilized by suitable steps before the aseptic filling.
  • the composite structure existing according to the prior art has only a barrier layer of water and water vapor impermeable material which protects the cardboard.
  • This layer is usually arranged on the product side and protects the carrier material against moisture from the product.
  • the polymer layer on the outside of the carrier material is only used for sealability, printability and as protection against "normal" environmental influences.
  • the object of the invention is to provide a composite material of the type mentioned at the outset and described in more detail above, in which the backing material layer is protected in such a way that a pack made therefrom with the product contained therein can be sterilized in an autoclave or the like , It is also desirable that the composite material can be produced simply and inexpensively. This object is achieved in that a further barrier layer is provided on the other side of the carrier material layer.
  • a package made from the composite material according to the invention can therefore be sterilized without problems in an autoclave even at higher sterilization temperatures.
  • the metal barrier layers applied to both sides of the carton are 'absolute' barrier layers and have the additional advantage that the holes or imperfections occasionally occurring during processing, especially when folding and folding, and during transport etc. a barrier layer, because of the intact second layer in front of or behind it, cannot have a negative impact on the shelf life of the packaged product.
  • the double metal layer thus leads to increased safety of the product quality with respect to e.g. B. Shelf life.
  • at least one connecting layer is arranged between the carrier material layer and the barrier layer.
  • Such a layer also called an adhesion promoter layer, ensures better contact between the carrier material and the barrier layers.
  • a further embodiment of the invention provides that at least one further connection layer is arranged between the barrier layer and the outer sealing layer. This measure also improves the adhesion between the barrier layer and the respective outer sealing layer.
  • the oxygen barrier layer consists of Al foil.

Abstract

L'invention concerne un matériau composite contenant du papier ou du carton en tant que matériau support (1), et présentant un revêtement plastique, notamment destiné à des emballages thermoscellables étanches à la lumière, aux gaz et aux liquides. Ledit revêtement plastique présente respectivement des couches de scellage extérieures (3), une couche barrière (2) en métal étant présente entre la couche de matériau support (1) et une des couches de scellage (3). L'invention concerne également un procédé de fabrication dudit matériau composite. L'invention vise à protéger la couche de matériau support (1) du matériau composite de manière qu'un emballage réalisé à partir dudit matériau composite, contenant un produit, puisse être stérilisé dans un autoclave ou similaire, ledit matériau composite pouvant être fabriqué de façon simple et économique. A cet effet, une couche barrière ultérieure (2) est disposée sur l'autre côté de la couche de matériau support (1).
