Special Issue Information

Dear Colleagues,

The rapid evolution of packaging technologies has intensified the demand for advanced polymeric materials that combine functionality, sustainability, and cost-effectiveness. This Special Issue, Trends and Innovations in Polymer Packaging Materials, aims to present recent innovations in polymer science that address emerging challenges in food safety, product protection, waste reduction, and circular economy strategies. Contributions should focus on the development, characterization, and application of novel polymers, polymer blends, composites, and bio-based alternatives engineered to improve key material properties, including mechanical strength, barrier performance, thermal stability, biodegradability, and recyclability.

In addition, for this Special Issue, studies on stimuli-responsive materials, smart and active packaging systems that improve shelf-life and product quality are welcome. Research addressing the environmental impact of polymeric packaging—such as recycling technologies, life-cycle assessment, and upcycling of industrial or agricultural waste into high-value polymer materials—is also highly encouraged.

By bringing together interdisciplinary research and industrial practice, this Special Issue aims to showcase cutting-edge polymer innovations that will shape the future of packaging. I hope this Special Issue will encourage researchers to contribute to the advancement of fundamental and applied knowledge on innovative polymer materials and technologies that are shaping the future of packaging applications.

The food packaging industry requires sustainable solutions to reduce plastic waste and replace synthetic additives. This study addresses the need for scalable methods to transform conventional polyethylene terephthalate (PET) packaging into active food preservation systems using natural biocides. Commercial PET packaging was surface-activated using industrial-scale corona treatment, followed by coating with natural biocides—carvacrol (CV) and trans-cinnamaldehyde (tCN). The resulting active packaging materials (PET-CV and PET-tCN) were characterized using XRD, FTIR, SEM, AFM, and desorption kinetics. Packaging properties including mechanical strength, oxygen barrier, antioxidant (DPPH), and antibacterial activity (against S. aureus and E. coli) were evaluated. Real-food preservation tests were conducted using fresh minced pork (4 °C, 6 days) and table olives (23 °C, 21 days), monitoring microbiological (TVC), colorimetric (CIE L*a*b*), and pH changes. Corona treatment successfully anchored both biocides through physical adsorption, with tCN exhibiting stronger surface interaction (desorption energy: 128.0 kJ/mol). Both coatings significantly improved oxygen barrier properties (61% reduction for PET-CV, 80% for PET-tCN). PET-tCN demonstrated superior antibacterial activity (inhibition zones: 15.0 mm against E. coli). In pork preservation, PET-tCN achieved a 2-log reduction in TVC, maintained meat redness (a*: 12.80 vs. 5.10 for control), and stabilized pH. For olives, PET-tCN reduced TVC by 2.35 log cycles and preserved green color. This corona-assisted coating approach, demonstrated here at laboratory scale, successfully transforms inert PET into multi-functional active packaging with potent antimicrobial, antioxidant, and barrier properties, significantly extending food shelf-life and offering a sustainable solution for reducing food waste.
