The research presents the results of experimental studies on the features of printing on composite biodegradable films made from a mixture of polyethylene and thermoplastic starches. Thermoplastic starches were produced based on native starches of different kinds by processing them in laboratory extruders of Brabender and MashPlast (Russia). Biodegradable hybrid compositions (BHCs) in the form of strands, pellets, and films were produced by mixing thermoplastic starches with polyethylene in extruders. The edge wetting angle of the BHC films was determined using a laboratory unit equipped with Image software (Russia), and the surface tension of the BHC films was determined using test ink (Germany). Modification of the surface of the BHC films was carried out in a laboratory unit using the method of film treatment with a "corona" discharge. The adhesion interaction of the paint coating on the BHC films was evaluated by the lattice incision method and the adhesive tape method. Changes in the chemical structure after "corona discharge" modification were determined by Fourier infrared spectroscopy. It was found that the surface properties of biodegradable hybrid compositions change when treated with "corona discharge" and the composite polymer films become suitable for the printing process, but during the treatment in the "corona discharge" plasma the BHCs do not change into the electret state.
