The weight of packaging materials will be increased with advanced innovations, such as multilayer plastic. The consequence of the advanced innovations is challenges in the following reuse activities. This study aimed to investigate the properties of multilayer plastic materials after recycling processes and will increase the awareness of plastic packaging material for reuse options. In this research, the materials were produced from food packages by crushing them and treating them with injection molding equipment. The implementation of materials in the processing was tested, and the structural and mechanical characteristics of the produced plastic materials was evaluated and discussed. Based on the completed tests, plastic materials used in food packages have the clearest differences in the material features, for instance, the melt flow rate and elongation rate in the tensile test that varied between 2.96–48.4 g/10min and 2–289%, respectively. The variation in the characterizations ranged widely between the material structures. The results indicate that solid plastic packaging materials have better mechanical features compared to foil materials. The structural analysis of materials showed that multilayer plastic includes a wide spectrum of different elements within materials, creating a challenge for future recycling.

Bacteriocins are proteinaceous toxin produced by bacteria to inhibit the growth of similar or closely related bacteria. Among lactic acid bacteria (LAB), bacteriocins are produced by <em>Streptococcus</em>, <em>Pediococcus</em>, <em>Lactobacillus</em>, etc. In recent years, bacteriocin-producing LAB have attracted significant attention because of their generally recognized as safe status and potential use as safe additives for food preservation. Incorporation of bacteriocins into packaging films to control food spoilage and pathogenic organisms has been an area of active research for last decade. Antimicrobial packaging film prevents microbial growth on food surface by direct contact of the package with the surface of food. The objectives of this study were to isolate bacteriocin-producing LAB from Yakult®, develop antimicrobial packaging system and evaluate their antimicrobial effects on selected spoilage and pathogenic microorganisms. For this reason, the antimicrobial packaging film was made by using the bacteriocin by <em>Lactobacillus casei</em> and coating it or adsorbing it onto the surface of different packaging materials. The antimicrobial activity of the coated films was tested by agar diffusion assay against the test organisms <em>Escherichia coli</em> and <em>Staphylococcus aureus</em>. The results obtained proved that bacteriocins can be used to inhibit both the test organisms. Thus antimicrobial packaging systems can be developed using bacteriocins thereby reducing the risk of pathogen development, as well as extending the shelf life of foods.
