Reshaping food packaging through biodegradable materials, biopolymer films and sustainable innovations
AI summary Read the abstract
This review paper rounds up new research on food packaging made from plants, algae, mushrooms, and other renewable materials that break down naturally instead of sticking around like traditional plastic. This matters because regular plastic packaging sheds tiny microplastic particles linked to health risks, and these biodegradable alternatives—some even edible—could keep food fresh while cutting down on plastic pollution and waste.
As countries continue to develop and grow, concerns associated with conventional plastic packaging have accelerated the search for sustainable packaging alternatives. Awareness is rising about the harmful effects of microplastics, which can pose serious health risks to humans, animals, aquatic life, and the broader environment. To support a greener future, researcher and industries from various fields including food industry has embraced biodegradable packaging derived from renewable sources such as plants, animals, and microorganisms, offering an eco-friendly solution. These materials help preserve quality, safety and extend the shelf life of food products. Technological advancements, including nanotechnology, biopolymer engineering, and the incorporation of active agents, have enhanced the mechanical strength, barrier performance, and functionality of biodegradable packaging. Biodegradable packaging can be break down easily when disposed off in soil or water, reducing environmental impact by minimizing pollution, microplastic formation, and landfill accumulation. This article will provide an introduction to microplastics, describe common manufacturing processes for biodegradable packaging, Innovations such as nanocellulose, algae-based plastics, microbial bioplastics, edible films, and mushroom-based materials highlight the versatility and discuss the decomposition rates of biodegradable plastics. Such innovations contribute to achieving zero waste, with some materials offering the potential for recycling and utilization of agro waste.
