In this article, we present polymer materials consisting of polylactide (PLA) and nisaplin (N), as well as PLA and natamax (X). These materials were obtained using the solvent method and tested by various test methods, i.e., functional properties—water vapor permeability, light transmission, gloss, and bactericidal activity against strains E. coli (ATCC 8739P), S. aureus (ATCC 65388), and P. aeruginosa (ATCC 8739). Furthermore, analyses were conducted to evaluate their efficacy against pathogenic fungi, including A. niger, A. flavus, A. glaucus, and A. versicolor. Mutagenicity analyses were performed using the standard Ames Test with Salmonella typhimurium. The main test methods used were ISO 22196, ISO 846. The results obtained confirm the potential suitability of the films of PLA with nisaplin and natamax for applications in the food packaging industry.
