This review examines the potential of nanomaterials in revolutionizing food packaging, focusing on their role enhancing barrier properties and extending shelf life packaged foods. Traditional packaging materials often fall short effectively protecting against oxygen, moisture, UV light, resulting diminished quality shorter life. Nanomaterials, including nanoclays, metal oxide nanoparticles (e.g., ZnO, TiO₂), carbon-based graphene, carbon nanotubes), biodegradable options like cellulose nanocrystals, have emerged as promising solutions. These offer exceptional gas moisture properties, antimicrobial effects, protection capabilities. The provides an in-depth exploration various nanomaterials, highlighting distinctive mechanisms; such tortuosity which enhance performance by limiting permeability. It also discusses recent advancements integrating into both flexible rigid systems, well active intelligent that employs nanosensors for real-time monitoring freshness spoilage. Despite potential, challenges toxicity concerns, environmental impacts, economic constraints to large-scale adoption are addressed. emphasizes need future research dual-function can simultaneously improve enable sensing. innovations could transform technologies, promoting enhanced safety sustainability.

Abstract The environment and public health are seriously at risk from the increasing levels of heavy metal (HM) pollution in water bodies, hence efficient remediation techniques must be developed. Unique physicochemical properties graphene (Gn) such as its enormous surface area, chemical stability, extraordinary adsorption capabilities have made it a promising candidate for application various processes. Recent studies indicate removal Gn‐based materials Gn oxide (GO) reduced GO (rGO) reach 99% efficiency rates lead (Pb 2+ ), cadmium (Cd mercury (Hg ) through strong electrostatic bonds coordination along with π‐π stacking interactions. In addition, selective nature adsorbents grows better functionalization because incorporates thiol, amine, sulfonic acid groups. integration metal–organic frameworks (MOFs) combined magnetic nanoparticles bio‐based polymers enhances increases stability while offering recyclability features. conclusion this study discusses current obstacles cost, scalability, environmental impact, selectivity potential future developments widespread use treatment, highlighting significance continued research to improve these substances useful applications. Practitioner Points Graphene‐based exhibit high capacity adsorbing metals, enhancing purification. Functionalization improves ability selectively target remove specific metals like lead. Graphene derivatives can achieve within minutes, making them treatment. Despite synthesis costs, graphene's superior performance may lower long‐term operational costs wastewater
