Bioactive polypropylene (PP) films with active agents) presence for food packaging application have been prepared and characterized. The novel modified PP films were obtained via PP/additives systems regranulation and cast extrusion. The influence of two types of plasticizers (natural agents as well as commercial synthetic product) and bioactive additives on final features, e.g., mechanical properties, was evaluated. Moreover, the biocidal activity of the films was determined. Due to their functional properties, they are developed as additives to packaging plastic materials such as polyolefins. The study results presented in our work may indirectly contribute to environmental protection by reducing food waste. The aim of the work was to obtain innovative, functional packaging materials with an ability to prolong the shelf life of food products. The best antimicrobial properties were observed for the sample based on 5 wt.% oregano oil (OO) and 5 wt.% cedar oil (OC) in PP matrix. A microbial test revealed that the system causes total reduction in the following microorganisms: , , , , , ,
已制备并表征了用于食品包装应用的含活性剂的生物活性聚丙烯（PP）薄膜。通过PP/添加剂体系的再造粒和流延挤出获得了新型改性PP薄膜。评估了两种类型的增塑剂（天然剂以及商业合成产品）和生物活性添加剂对最终性能（如机械性能）的影响。此外，还测定了薄膜的杀菌活性。由于其功能特性，它们被开发为聚烯烃等包装塑料材料的添加剂。我们工作中呈现的研究结果可能通过减少食物浪费间接有助于环境保护。这项工作的目的是获得具有延长食品保质期能力的创新型功能性包装材料。在PP基体中基于5 wt.%牛至油（OO）和5 wt.%雪松油（OC）的样品观察到了最佳抗菌性能。微生物测试表明，该体系能使以下微生物总数减少： ， ， ， ， ， ，
