A Review of Nonbiodegradable and Biodegradable Composites for Food Packaging Application
AI summary Read the abstract
This review compares nonbiodegradable and biodegradable composite materials for food packaging, examining mechanical properties, barrier performance, and end-of-life degradation behavior. The authors identify biodegradable composites as technically feasible alternatives to conventional plastic packaging but highlight cost and processing challenges that currently limit their widespread commercial adoption.
The dependency on nonbiodegradable-based food packaging, increase in population growth, and persistent environmental problems are some of the driving forces in considering the development of biodegradable food packaging. This effort of green packaging has the potential to solve issues on plastic wastes through the combination of biodegradable composite-based food packaging with plant extracts, nanomaterials, or other types of polymer. Modified biodegradable materials have provided numerous alternatives for producing green packaging with mechanical strength, thermal stability, and barrier performance that are comparable to the conventional food packaging. To the best of our knowledge, the performance of nonbiodegradable and biodegradable composites as food packaging in terms of the above properties has not yet been reviewed. In this context, the capability of biodegradable polymers to substitute the nonbiodegradable polymers was emphasized to enhance the packaging biodegradation while retaining the mechanical strength, thermal stability, barrier properties, and antioxidant and antimicrobial or antibacterial activity. These are the ultimate goal in the food industry. This review will impart useful information on the properties of food packaging developed from different polymers and future outlook toward the development of green food packaging.

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.
A Comprehensive Review of Biodegradable Polymer-Based Films and Coatings and Their Food Packaging Applications
AI summary Read the abstract
This review covers the development of biodegradable polymer-based films and coatings as alternatives to conventional plastic food packaging. While these bio-based materials reduce long-term environmental pollution, the review notes that they can still break down into microplastic particles under certain conditions. The shift to biodegradable packaging may reduce but not eliminate the food packaging contribution to microplastic pollution and human exposure.

A Review on Biopolymer-Based Biodegradable Film for Food Packaging: Trends over the Last Decade and Future Research
AI summary Read the abstract
This systematic review explores biodegradable packaging made from natural materials like starch and proteins as alternatives to conventional plastics. Reducing plastic packaging is important because traditional plastics break down into microplastics that contaminate food and the environment.
Comparative Analysis of the Environmental Impact of Biopolymer-Based and Conventional Plastic Packaging in Food Engineering Applications
AI summary Read the abstract
This review compares plant-based biodegradable packaging materials with traditional plastics like PET and HDPE used in food packaging. While bioplastics produce fewer carbon emissions and break down more easily, they still face cost and performance challenges. The study matters because conventional plastic packaging is a major source of microplastic pollution in the environment.
