Special Issue Information

Dear Colleagues,

This Special Issue, "Novel Functional Coatings for Food Packaging: Recent Advances and Future Challenges", will focus on recent innovations and future directions in the field of functional coatings for food packaging. Our aim is to showcase advanced materials and technologies that will improve the performance of packaging systems in terms of food preservation, safety, functionality, and environmental compatibility.

We invite contributions that explore new formulations and applications of functional coatings, with our particular interest being materials that respond to current demands for sustainability and smart packaging. Topics of interest include, but are not limited to, the following:

  • Coatings derived from renewable, bio-based, or biodegradable resources;
  • Systems with antimicrobial, antifungal, or antioxidant activity;
  • Smart or responsive coatings with sensing or monitoring capabilities;
  • Enhancements in barrier performance against gases, moisture, or light;
  • Nanostructured or hybrid coating materials for multifunctional applications;
  • Innovations supporting recyclability, compostability, or regulatory compliance.

By bringing together a wide range of research and perspectives from both academia and industry, this Special Issue aims to provide a platform for interdisciplinary dialogue. It also seeks to outline the key scientific challenges and opportunities around translating laboratory advances into scalable, real-world packaging solutions.

We aim to highlight both fundamental research and practical applications, as well as identify existing gaps and future challenges in the field. Contributions from academia and industry are equally encouraged to foster interdisciplinary collaboration and innovation in sustainable food packaging technologies.

Polysaccharide-based edible coatings are increasingly explored as sustainable strategies for maintaining quality of fresh produce, acting as barriers to gas exchange while improving mechanical and optical properties. However, their effectiveness depends not only on the intrinsic features but also on the structural and physiological diversity of fruits and vegetables, which vary in peel composition, hydrophobicity, and texture. This study investigated plant-derived polysaccharide films (cassava starch, potato starch, corn starch, carboxymethylcellulose, hydroxypropylmethylcellulose, and pectin) characterized for moisture resistance, solubility, permeability, thermal stability, hydrophilicity, opacity, gloss, and mechanical strength. Concurrently, different fruits and vegetables (fruit, root, and tubers) were analyzed for their surface hydrophilicity to establish correlations between film properties and peel characteristics. The findings emphasize that no single polymer can be universally applied. In addition, the choice of matrix must be guided by both film functionality and produce surface traits. Starch-based films presented high hydrophilicity, suggesting better wettability, while pectin and cellulose derivatives presented distinct advantages for less hydrophilic peels. This work highlights the importance of tailoring edible coatings according to the physicochemical compatibility between films and fresh produce surfaces, providing insights for improving post-harvest preservation strategies and guiding the development of effective, sustainable coatings for diverse horticultural commodities.
