Abstract
The increasing environmental impact of plastic waste has accelerated the search for sustainable alternatives to conventional packaging. This study focuses on developing fully biodegradable food packaging films based on natural polymers, such as chitosan. Derived from renewable resources, these materials, offer excellent biodegradability and reduced environmental harm, making them promising candidates for eco-friendly packaging solutions. However, their practical application is often hindered by limited mechanical strength and high moisture sensitivity.
To overcome these limitations, this research explores a new film by incorporating nanolignin particles. Additionally, chestnut extract was included for its antibacterial properties, effectively extending the shelf life of packaged food. In this research the hydrophilic properties of the films were measured, including contact angle, moisture content, degree of swelling, and water solubility. Next, mechanical properties, such as tensile strength and elongation at break, were analyzed. The films with chosen number of additives demonstrated the most favorable results, highlighting the potential of nanolignin integration. To gain deeper insights, advanced analytical techniques including SEM, FT-IR and UV-VIS were employed. The films water vapor permeability was also assessed, underscoring their suitability for food packaging applications. These biodegradable films exhibit satisfactory mechanical, hydrophilic, and barrier properties, positioning them as a viable alternative to conventional plastics.
