Abstract

L'invention concerne une feuille composite 27 pour le revetement de récipients à liquides. La feuille est constituée de plusieurs couches 1, 2, 3. La couche supérieure de la feuille 1 et la couche inférieure de la feuille 3 sont électriquement neutres et la couche intermédiaire de la feuille 2 est conductrice et subdivisée en zones électriquement isolées 7, 8. Cette disposition permet de provoquer un signal d'alarme ainsi qu'une détermination précise de l'emplacement d'une fuite, en cas d'apparition d'une fuite.The invention relates to a composite sheet 27 for coating liquid containers. The sheet consists of several layers 1, 2, 3. The upper layer of the sheet 1 and the lower layer of the sheet 3 are electrically neutral and the intermediate layer of the sheet 2 is conductive and subdivided into electrically isolated zones 7, 8 This arrangement makes it possible to trigger an alarm signal as well as a precise determination of the location of a leak, in the event of the appearance of a leak.
