description: The object of research is aluminum metalized film of polypropylene with thickness of 4 microns. The aim is to establish the peculiarities of formation of electric breakdown channel in thin polypropylene film. The formation of a breakdown channel in a 4 Î¼m-thick polypropylene film with a one-sided aluminum coating with a thickness of 20 nm under the effect of a constant electric field on the film has been studied. The energy consumed by the breakdown of the samples was determined by the capacitance of an additional capacitor connected in parallel with the sample. The breakdown channel diameter in polymer film was found to be independent of the discharge energy and was 16Â±3 Î¼m, and the energy for its formation was estimated to be 6 Î¼J. The area of demetallized region of the film surrounding the breakdown channel and resulting from aluminum evaporation during film breakdown increases in direct proportion to the discharge energy. The research of conditions under which the conductive and breakdown channels are formed and the opportunity to minimize the breakdown channel effect on the electric characteristics of electronic devices is an urgent task of not only scientific but also great practical importance. When writing the literature review the methods of information search and analysis from the following sources and databases were applied: Google Academy, scientific electronic library eLibrary, Scopus database.
