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 μg*μm/cm2/min. The structured fluoropolymer film exhibits a higher resistance to strain and retain barrier properties during manufacture and/or use.
