Abstract: This article analyses the results of a study into the physical and mechanical properties of conventional LDPE (low-density polyethylene) plastic film and two types of biodegradable films. Compostable packaging offers considerable potential as an alternative to traditional plastics, contributing to the development of environmentally friendly materials. The study into this area provides valuable knowledge that responds to both current environmental protection needs and to associated legal requirements. Bioplastics have a wide range of applications in the packaging industry; however, there is a lack of research on their usability in contact with all types of food. A significant part of this article focuses on the analysis of the results of the environmental resistance of bioplastics and on their preliminary compostability assessment.
