Development of natural organic acid cross-linked PVA/starch films with enhanced physicochemical and antioxidant properties for extending the shelf life of Malus domestica

N,S-Co-Doped Carbon Dot-Reinforced Biopolymer Films with Enhanced Barrier, Antioxidant, and Antimicrobial Performance for Active Food Packaging

The development of sustainable active food packaging materials with multifunctional protective capabilities is highly desirable for improving food safety and extending shelf life. In this study, sulfur- and nitrogen-rich carbon dots (GLCDs) were synthesized from glycine and lipoic acid through a facile hydrothermal app...

Barium Crosslinking in Bio‐Based Sodium Alginate Films: Improved Barrier and Thermal Performance Toward Biodegradable Packaging Applications

Growing environmental concerns associated with petroleum‐based plastics have intensified the demand for sustainable, biodegradable materials for packaging applications. Sodium alginate is a natural polysaccharide with excellent biodegradability, biocompatibility, and film‐forming ability; however, its high moisture...

Smart and active packaging based on thermoplastic starch and gelatin blends with curcumin, micro/nanocellulose, and tea tree oil.

Biodegradable materials with active and intelligent functionalities have attracted increasing interest as sustainable alternatives to conventional food packaging. This study developed and characterized thermoplastic starch (TPS)/gelatin films containing curcumin (Cur) as a pH-sensitive indicator, tea tree essential oil...

Smart Multifunctional Biocomposite Films from Tamarind Seed Starch/Cotton Waste Fibre, and Butterfly Pea (Clitoria ternatea) for Sustainable Food Packaging

A green, chemical crosslinker-ternary macromolecular film from soy protein, Camellia waste, and carrageenan via Maillard reaction for food preservation.

Bio-based packaging films are promising alternatives to petroleum-based plastics, but their application is limited by chemical crosslinkers, high feedstock costs, and performance-sustainability trade-offs. Here, a crosslinker-free ternary film (SCC) was fabricated from soy protein isolate, Camellia oleifera cake extrac...

Design and Functional Characterisation of Bio-Based Multilayer Polylactic Acid Films Incorporating Chitosan and Propolis for Antimicrobial Food Packaging Applications

: The development of renewable and bio-based materials with functional performance comparable to conventional plastics remains a key challenge in sustainable packaging. In this study, bio-based multilayer films were fabricated using polylactic acid (PLA) as a renewable polyester substrate, combined with chitosan (CS) a...
