Recent Advances in PBAT (Nano) Composite Materials for Food Packaging: A Comprehensive Review
AI summary Read the abstract
This review surveys advances in PBAT-based biodegradable nanocomposites for food packaging, covering fabrication methods and nanofillers that improve the mechanical strength, barrier properties, and antimicrobial performance of this promising sustainable alternative to conventional plastic packaging.
ABSTRACT Advancements in food packaging aim to meet consumers' evolving preferences for healthier and eco‐friendly products. Traditional plastics used in packaging are unsustainable and harm the environment, prompting interest in eco‐friendly alternatives. However, bio‐plastic materials often have low barrier and mechanical properties that can be improved with reinforcement. Bio‐degradable polymers, such as PBAT, have unique properties that make them suitable for food packaging applications. PBAT‐based composites with nanofillers have attracted attention due to their ability to enhance the mechanical and thermal stability, barrier, contact angle, and antimicrobial activity of the material. The present review comprehensively discusses the progress in PBAT‐based food packaging materials. Furthermore, a brief insight is given into the fabrication methods used to create these composites, the various techniques employed to characterize their properties, and the potential applications of these innovative materials in the food packaging industry.

This paper reviews advances in nanocomposite and biopolymer-based food packaging materials, noting that microplastic pollution has been detected globally and is a recognized threat to ecosystem and human health. It briefly contextualises microplastics as a motivation for developing biodegradable packaging alternatives, though the primary focus is materials science rather than microplastics research per se.
Biodegradable nanocomposite films containing combined ZnO and TiO₂ nanoparticles in PBAT: A strategy to mitigate microplastic persistence from food packaging
AI summary Read the abstract
This study created new biodegradable food packaging films by combining a plant-based polyester (PBAT) with zinc oxide and titanium dioxide nanoparticles, finding that the combination accelerated the material's degradation while also improving its mechanical and safety properties. The goal was to develop packaging that breaks down faster in the environment, producing fewer persistent microplastics compared to conventional plastics. Results suggest certain nanoparticle concentrations produce materials that are both commercially viable for packaging and meaningfully less likely to accumulate in ecosystems.
