    Abstract: The present invention refers to a structure comprising a biaxially oriented polypropylene (BOPP) film having at least one layer comprising a homopolymer of propylene which layer is in contact with an oil phase, the homopolymer of propylene has a) a content of isotactic pentads in the range from 95% to 98%, and b) a content of ash of not more than 30 ppm, based on the total weight of the homopolymer of propylene, characterized in that the oil phase has an absorbance value of ≤0.1, relative to the pure oil, as determined spectrophotometrically at a wavelength of 860 nm by the reduction of transmitted light intensity. The present invention further refers to the use of a biaxially oriented polypropylene (BOPP) film for making capacitors comprising said structure, wherein the oil phase has an absorbance value of ≤0.1, relative to the pure oil, as determined spectrophotometrically at a wavelength of 860 nm by the reduction of transmitted light intensity as well as the use of the homopolymer of propylene for increasing the life time of a capacitor.

    Abstract: Composite film (1) for closing a container (10) by sealing the composite film (1) against a circumferential sealing surface (11) of the container (10) or of a cap ring (12) to be connected to the container (10). The composite film (1) comprises an outer support layer (30) made of a metal film and an inner multilayer membrane (20) laminated to the outer support layer (30) using a bonding layer (28). The membrane (20) has a consecutive layer structure from the outside to the inside consisting of a backbone layer (21) made of polypropylene, an intermediate layer (23) made of a partially crystalline polyamide and a cohesively breakable peeling layer (25) made of polypropylene, polyethylene and talc, wherein between the intermediate layer (23) and the backbone layer (21) as well as between the intermediate layer (23) and the peeling layer (25) there is arranged a tie layer (22, 24) made of a maleic acid anhydride grafted polypropylene. The membrane has further an innermost sealing layer (26) made of a random copolymer comprising monomers of propylene, ethylene and butylene, wherein the random copolymer is grafted with maleic acid anhydride. The softening point of the sealing layer (26) lies at least between 15 and 25° C. lower than that of the tie layers (22, 24). A use and a method of producing said composite film (1) are also disclosed.
