Results of experiments on the deposition of multilayer low-emission coatings with “oxide-metaloxide” structure on polyethylene terephthalate film by magnetron sputtering are presented. The purpose of this work was to find the composition of coatings which would have high moisture resistance and the possibility to operate outside sealed glass units. For this purpose, coatings with TiO

structures were proposed and their optical and electrical characteristics were investigated. The optimum thickness of coating layers which provides a good ratio of coating transparency in the visible range with reflection in infrared spectral region was obtained. It was shown that low-emission coatings based on a Ag layer have a higher transparency (82%) and reflection in the infrared region (93%) than coatings based on a Cu layer, for which these characteristics are 60% and 84%, respectively.
