摘要： A process for obtaining a film that comprises the incorporation of natural antimicrobial agents in a polymeric structure for the development of packages designed to increase the shelf life of chilled or refrigerated meat, preferably fresh chilled salmon; said process comprises the following steps: a) mixing a first extrusion of the antimicrobial active agent with low density polyethylene powder to obtain a pellet; b) a second extrusion to obtain a film incorporating the pellet obtained in step (a) in a proportion of 10% polyethylene pellets; c) conduct a three-layer coextrusion to develop the film into which the antimicrobial agent is incorporated, wherein the antimicrobial active agent is incorporated into the film layer which is in direct contact with salmon, where the binder, the middle and the outer structure of the film, provide the requirements for the film structure, without the incorporation of the active agent.
