Zusammenfassung:	A structured fluoropolymer film including a plurality of structures having a height at least two times a thickness of a corresponding unstructured fluoropolymer film and at least a 20% increase in displacement induction period when compared to the corresponding unstructured fluoropolymer film when measured in a biaxial tensile curve at a temperature of about 125 °C. In addition, the structured fluoropolymer film has a methane permeability of less than 500 µgµm/cm2/min. The structured fluoropolymer film exhibits a higher resistance to strain and retain barrier properties during manufacture and/or use. La présente invention concerne un film fluoropolymère structuré comprenant une pluralité de structures ayant une hauteur égale à au moins deux fois une épaisseur d'un film fluoropolymère non structuré correspondant et au moins une augmentation de 20 % de la période d'induction de déplacement par rapport au film fluoropolymère non structuré correspondant lorsqu'elle est mesurée dans une courbe de traction biaxiale à une température d'environ 125 °C. De plus, le film fluoropolymère structuré a une perméabilité au méthane inférieure à 500 µg µm/cm2/min. Le film fluoropolymère structuré présente une résistance à la contrainte plus élevée et conserve des propriétés de barrière pendant la fabrication et/ou l'utilisation.
