FIELD: chemistry.
SUBSTANCE: invention relates to production of packaging materials for food products and beverages, particularly barrier films, laminated packaging materials and packaging containers. The barrier film has a base polymer film and a barrier layer containing an inorganic oxide deposited on the base film via gas-phase deposition. The layer of inorganic oxide is additionally coated with a healing layer of cross-linked organopolysiloxane which is covalently bonded with the inorganic layer. The laminated packaging material has a barrier film. The packaging container is made from said barrier film.
EFFECT: packaging material has good barrier properties with respect to oxygen and water vapour, improved strength and softness.
