Experimental results of research on the structure and chemical constitution of the polymer film’s surface modi- fied by processing with gaseous fluorine are presented. The influence of different modes of fluorination of PE, PVC, PI and PET films on change of their surface properties has been researched by using methods of scanning electron microscopy, MBFIR (Multirepeadly Broken Full Internal Reflection) IR-spectroscopy and evaluation of friction factors. It has been shown that surface modi- fication of polymer films takes place on nano-level and leads to increasing barrier properties of materials relative to moisture and oxygen. Nowadays in printing industry a considerable growth of volumes of printed products with use of polymer films as substrates can be observed. Po[...]
