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.

Functional coatings for food packaging offer innovative approaches to extend shelf life, preserve quality and introduce active properties such as antimicrobial or antioxidant effects. These coatings include natural bio-based films (e.g., polysaccharide or protein-based) and synthetic polymers enhanced with additives or nanomaterials. Despite their advantages (e.g., improved barrier properties, spoilage inhibition, or intelligent sensing) they also pose safety concerns. Migration of chemical constituents and additives into food can lead to toxicological risks, such as cytotoxicity or endocrine disruption. Non-intentionally added substances (NIASs) and nano-sized components further complicate safety assessments. This review outlines the main types of functional coatings, their active mechanisms, and associated safety issues. Particular focus is placed on migration phenomena, chemical interactions and health risks from common migrants including plasticizers, monomers, nanoparticles and essential oils. The EU Packaging and Packaging Waste Regulation (Regulation (EU) 2025/40), adopted in December 2024 and published in the Official Journal in January 2025, introduces comprehensive sustainability and substance-restriction requirements, including strict criteria for food packaging materials that will apply from 12 August 2026. Emerging challenges include the assessment of bio-based and recycled coatings and the toxicology of nanomaterials. Balancing functionality with safety remains crucial for next-generation, sustainable and health-compliant food packaging. Full article
