The widespread use of single-use plastic packaging for pasteurized milk has become a pressing environmental and public health concern. Despite offering convenience and cost-efficiency, these plastic pouches contribute significantly to plastic pollution, pose recycling challenges, and may release microplastics or chemical contaminants, thereby endangering ecosystems and potentially human health., Pasteurized milk in many countries, especially in developing nations like India, is predominantly packaged in low-density polyethylene (LDPE) plastic pouches. These single-use plastics are lightweight and economical but are difficult to recycle due to contamination from milk residues and a lack of proper segregation. A majority of these pouches end up in landfills or open environments, where they degrade slowly, leaching harmful chemicals and breaking down into microplastics that enter soil, waterways, and food chains. Additionally, studies have indicated the possibility of chemical migration from plastic to milk under certain conditions of storage, especially in hot climates. The increasing awareness of such risks has led to growing public demand for sustainable packaging solutions, yet the industry continues to rely on plastics due to logistical and financial reasons
