Abstract
The present invention relates to a fluorinated composition and a fluorinated film having properties that make it suitable for use outside, especially in the agricultural sector. The film according to the invention is a single-layer polymer film comprising a polyvinylidene fluoride (PVDF) matrix and at least one impact modifier having a polyorganosiloxane core and at least one thermoplastic shell, in which the weight content of impact modifier varies between 2.5% and less than 40%. According to one embodiment variant, the invention relates to multilayer films comprising at least one layer of said fluorinated film and at least one layer of unmodified PVDF.
