A process for producing a packaged bandage, comprising the successive steps of:- preparation at a temperature comprised between 70 and 95°C of an aqueous solution of agar, polyvinylpyrrolidone (PVP) and sodium alginate；- casting of said solution in a mold cavity and cooling at room temperature, so as to convert said solution into a thermolabile gel；- addition of divalent metal ions to said gel with the formation of a body that contains a hydrogel of said divalent metal alginate and agar, and that separates from the walls of the mold；- extraction of said body from the mold；- insertion of said body within a casing；- sealing of said casing； and- irradiation of said sealed casing with a gamma and/or beta radiation, so as to cause the cross-linking of PVP and exert sterilization action.
