Abstract: The aim of this research was to solve the problems of accidental ingestion of microplastics such as in case of tea bag filter, in addition to the solid wastes management of food packaging plastics after use. PLA was not only aerobic compostable but also anerobic digested to biogas by methane fermentation at 50°C after a month, similar to that in composting at 60°C. Also, PLA was hydrolytic degraded in physiological saline solution at 37°C, that is the simulated condition of human body. Due to the relative slow degradation rate of PLA, its medical applications have been mainly to bone-fixation, taking about three months. The degradation of PLA in the human body by hydrolytic scission of ester linkage yielded lactic acid which was a naturally occurring acid without ill effects. It was suggested that PLA would remain temporarily in the body and disappear upon biodegradation followed by bioabsorption.

Abstract: Bio-based and sustainable food packaging technology has emerged as a crucial solution to address the environmental impact of conventional plastic packaging. Bio-based food packaging represents a vital advancement toward environmentally sustainable solutions in the food industry. These materials, derived from renewable biological sources such as polysaccharides, proteins, and biopolymers, offer significant benefits including reduced dependency on fossil fuels, biodegradability, and potential for compost ability, all contributing to lowered plastic pollution and carbon footprint. Their capacity to protect and preserve food while minimizing environmental impact aligns closely with global sustainability goals and growing consumer demand for eco-friendly products. Nevertheless, challenges remain in performance optimization, cost competitiveness, scalability, and regulatory acceptance that must be overcome for broader implementation. Addressing these obstacles requires continued research into enhancing mechanical and barrier properties, innovation in active and intelligent packaging technologies, and robust policy support to foster market adoption. Collaboration across industry, academia, and policymakers will be crucial to accelerating these developments. Looking ahead, the integration of emerging materials such as nanocomposites, advances in circular economy models, and stronger regulatory frameworks offer promising pathways to sustainable growth. Future research focusing on lifecycle impact reduction, multifunctional materials, and consumer education will ultimately drive the transition to a more sustainable packaging future. By embracing these innovations and commitments, bio-based food packaging stands to play a pivotal role in reducing environmental burdens while supporting food quality and safety. The review also discusses major challenges including material performance limitations, scalability, cost, and regulatory aspects. Finally, it highlights future prospects involving advanced bio-composites, active and intelligent packaging innovations, and circular economy integration, emphasizing the importance of multidisciplinary strategies for transitioning towards sustainable food packaging systems.
