Method for producing a temporarily water-resistant, biodegradable polymer packaging film, in which polyvinyl alcohol, cornstarch, citric acid are dissolved and mixed in an aqueous medium at a temperature of 85–90 °C, and after cooling to 50–60 °C, forming a film in a horizontal plane-parallel mold and crosslinking it by heat treatment at a temperature of 140–160 °C for 0.3 hours. An aqueous solution of polyvinyl alcohol, cornstarch, and citric acid is additionally mixed with the plasticizer triethyl citrate and nanocrystalline cellulose as a reinforcing agent.
