From a general point of view, the present invention relates to a material which has a high degree of impermeability to gases, especially to atmospheric oxygen, and which is particularly suitable for the manufacture of containers for easily oxidizable foods or beverages such as, for example, beer, milk, "soft drinks", and fruit juices. In particular, the present invention relates to a method for the preparation of polymeric material with a high degree of impermeability to gases, the method comprising the step of subjecting the polymeric material to a high-pressure treatment. |
