Food packaging protects food products, ensures food safety and hygiene, and reduces food waste by extending shelf life. The environmental concern for the growing rate of waste together with legislation aimed at restricting single-use materials directs the focus of the food industry towards the development of more sustainable materials, among which is the use of polylactic acid (PLA). The objective of this work was to evaluate the behavior of a new compostable film, based on PLA with wrapping in KRAFT paper and an exclusive PLA window for product visualization, in washed ready-to-eat salads, compared to bioriented polypropylene (BOPP). . The products were prepared and packaged in the Primaflor fresh-cut salad industry, produced under standard production conditions. The experiments were carried out with three different product references (mézclum, trocadero and gourmet) in five manufacturing batches with both films. The samples were evaluated from the first day of packaging until the end of their shelf life, stored for 4 days at 1-4ºC and 7-9 more days at 6-8ºC. The evolution of the gas content of the internal atmosphere of the container was determined, a descriptive sensory analysis was carried out by a panel of experts using a 5-point hedonic scale, and their expiration date was determined. The composition of the internal atmosphere was similar between the two packages (PLA+KRAFT and BOPP). At the sensory level, no significant differences were observed between the two types of packaging, since the shelf life of the products was the same in the three references under study. The microbiological results for the samples packaged in PLA+KRAFT were satisfactory up to 12 days of testing, as in the references packaged in BOPP. Therefore, it could be determined that the PLA+KRAFT container maintains the same safety date of the fresh-cut salads tested as the BOPP film and, furthermore, is a more sustainable alternative
