Abstract
Nowadays, the packaging market is the industrial sector that uses the most plastic and, consequently, generates the most waste. The high level of contamination derived from this waste has driven the demand for biodegradable packaging products as a potential solution, especially for single-use packaging that often ends up in nature. In this sense, the most environmentally friendly polymeric materials are those capable of being degraded under ambient conditions. A detailed example, subject of this study, is poly(butylene succinate-co-butylene adipate) (PBSA). In addition to biodegradability and compostability, these materials are attributed with good mechanical properties, such as tensile strength and elongation at break. However, these materials have not yet been implemented in the packaging sector due to their fragility and low barrier properties. This work bets on the modification of PBSA by incorporating reinforcements in order to improve the physical and mechanical properties making easier its incorporation in the general industry, and particularly in the packaging sector. For this reason, in this work we have obtained bionanocomposites and studied their subsequent transformation for injection and obtaining films by cannulation, being the two most used processes in this sector.
