ClearA review of biodegradable thermoplastic starches, their blends and composites: recent developments and opportunities for single-use plastic packaging alternatives
This review analyzed how different plasticizers, compatibilizers, and essential oils affect biodegradable thermoplastic starch blends and composites. The study suggests these materials offer promising alternatives to single-use plastic packaging, highlighting recent developments in improving their mechanical and barrier properties.
A Review on Biopolymer-Based Biodegradable Film for Food Packaging: Trends over the Last Decade and Future Research
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.
Introduction to Starch-Based Bioplastics
This review introduces starch-based bioplastics as a sustainable alternative to conventional fossil fuel-derived plastics, examining the composition and properties of starch polymers. The study discusses how starch-based materials could help address microplastic pollution concerns associated with traditional plastics, though challenges remain in improving their mechanical strength and moisture resistance.

Researchers developed a seaweed-based bioplastic film using Gracilaria edulis algae combined with starch, glycerol, and chitosan. The resulting material showed mechanical properties comparable to starch-based commercial plastics, good biodegradability, and compostability, and showed potential for use in low-moisture food packaging. This work contributes to the effort to replace petroleum-based plastics with renewable alternatives that break down in the environment rather than persisting as microplastic pollution.
Advancements in the biopolymer films for food packaging applications: a short review
This review covers advances in biodegradable biopolymer films being developed to replace conventional plastic food packaging, which breaks down into microplastics that contaminate soil and water. While these plant-based alternatives show promise for reducing microplastic pollution, they still need improvements in strength and durability before they can compete with conventional plastics at commercial scale.
