Abstract: front page image
(DE)Die Erfindung betrifft eine Verbundfolie (1) mit Barriereeigenschaften. Die Aufgabe, eine Verbundfolie, welche bei guter Verarbeitbarkeit eine hohe Barriereeigenschaft bezüglich Wasserdampf und gasförmigen Stoffen aufweist und unproblematisch entsorgt werden kann, zur Verfügung zu stellen, wird dadurch gelöst, dass die Verbundfolie (1) mindestens eine Ethylen−Vinylalkohol (EVOH)−Folienschicht (2) und mindestens eine Cyclo−Olefin−Copolymer (COC)−Folienschicht (3) umfasst.
(EN)The invention relates to a composite film (1) with barrier properties. The aim of the invention is to provide a composite film which can be easily worked, has good barrier properties to steam and gaseous materials and can be easily disposed of. Said aim is achieved, whereby the composite film (1) comprises at least one film layer (2) of ethylene vinyl alcohol (EVOH) (2) and at least one film layer (3) of a cyclo-olefin copolymer (COC).
(FR)L'invention concerne un film composite (1) ayant des propriétés de barrière. L'invention vise à fournir un film composite qui ait non seulement une bonne aptitude au façonnage mais aussi de bonnes propriétés de barrière vis-à-vis de la vapeur d'eau et de matières gazeuses et dont l'élimination ne pose aucun problème. A cet effet, le film composite (1) contient au moins une couche d'éthylène-alcool vinylique (EVOH) (2) et au moins couche de copolymère cyclo-oléfine (COC) (3).
