Obtenu00c7u00e7o films poliolefinicos additives with antimicrobials based silver to increase shelf life and / or manutenu00c7u00e7o color in meats and products carneos.Invention patent for a process of obtaining polymeric films containing antimicrobial agents based on silver, with activity of colour maintenance and preservation of the food with respect to gram negative and positive bacteria for use in meat, particularly CA Bovine rnes vacuum packed.Pellets of polyolefins, mixed the predetermined concentration of silver based antimicrobial agent, were obtained in the form of pasta after the extrusion. Different amounts of masterbatch were mixed in mixer helix, to the resin and extruded by blowing to obtain D And films with different degrees of antimicrobial activity.The process of adding antimicrobial agent did not alter the mechanical properties of the film, which showed to be effective for conservation of microbial quality in respect of pathogenic microorganisms and spoilage of vacuum packaged meat, developing color desirable to co Nsumo.
