The paper considers the prospects of creating barrier polymer film materials with nanocomposite coatings based on layered aluminosilicates. The use of nanocomposite coatings has prospects for obtaining multilayer packaging materials characterized by high barrier properties, recyclability, and also reduces the cost of packaging by incorporating economically available polymeric materials and fillers. The application of gas-discharge treatment of polymer films prior to coating leads to increased adhesion of the films to the functional nanocomposite coatings, which can be used to create multilayer film materials with improved performance characteristics.
