Innovative composite packaging films were obtained from poly (lactic acid) (PLA) and polyacrylate. Mechanical properties, permeability to water vapor and carbon dioxide through the composite films, as well as their resistance to ultraviolet radiation used in the sterilization process were studied. The influence of refrigeration -18°C on the properties was tested. An improvement in barrier and mechanical properties of the composites with respect to the pure PLA was found, as well as their good photochemical stability and resistance to low temperatures, which makes it possible to use these composites in the food packaging production.
