摘要

The escalating interest in mitigating environmental degradation and food safety has induced a paradigm shift in the packaging segment towards sustainable and eco-benign materials. In recent decades, biopolymeric bionanocomposites and polymeric nanocomposites (PNC) have emanated as panacea for next-generation food packaging, attributable to their unique features, including enhanced barrier inhibition, mechanical strength, and antimicrobial affinity. The escalated quest for sustainable and elevated- food packaging performance has resulted in green nanomaterials (NMs) exploration as feasible replacement for synthetic materials. Biopolymeric bionanocomposites offer several benefits over traditional materials, including improved biodegradability, renewability, and eco-friendliness making them suitable alternatives to synthetic plastics, which contribute to environmental pollution and health hazards, thus enhancing their application in biomedical, water treatment, and food industries. Generally, conventional packaging materials compete in order to provide appropriate protection against UV light, oxygen, moisture, and so on, which escalates food deterioration thereby minimizing shelf life. A comparison between synthetic and green NMs depicts the urgency for eco-benign replacments, which emphasizes their biodegradability, sustainability and minimization of their environmental foot-print. The food packaging industry faces significant challenges, primarily centered on sustainability, safety, and transparency. Other concerns include the environmental impact of packaging waste, the need for sustainable alternatives to traditional plastics, and ensuring food safety through effective contamination prevention measures. Thus, this paper critically elucidates these challenges charting a pathway for mitigation. Herein, notable mechanisms affecting barrier performances, including gas and moisture transmission control, the tortuosity effect, as well as nanoparticle structural effects undergo indepth evaluation. Additionally, NMs effect on the films crystallization disposition is analyzed to expose their function towards enhancing structural integrity and general performances. Therefore, this paper provides in-depth elucidation of sustainable polymeric nanocomposites for food packaging, with focus on their development, features, applications, and future perspectives.
