Abstract: Title: EcoPack: Innovative Packaging Solutions from Arecanut Leaf Sheaths (ALS) The present invention relates to an eco-friendly and sustainable packaging solution using arecanut leaf sheaths (ALS) to create versatile products such as bottles, sachets, and corrugated boxes. The invention involves processing ALS through cleaning, enzymatic treatment with cellulases and pectinases, and mechanical pressing to enhance flexibility, strength, and moldability. The treated ALS sheets are converted into continuous rolls and molded into complex forms using heat and pressure, with natural plant-based coatings and adhesives applied to improve water resistance, leak resistance, and structural integrity. An automated system is developed for filling and sealing ALS-based sachets and bottles, ensuring compatibility with existing industrial packaging systems and enabling large-scale production. The polysaccharide composition of ALS, including cellulose (65.25%), hemicellulose (32.20%), lignin (24.50%), and pectin (4.15%), contributes to the mechanical strength, flexibility, and biodegradability of the final product. Ash content of 5.40% improves heat resistance and rigidity, while glycoproteins (1.02%) and galactose (3.75%) enhance durability and surface finish. Successful prototypes of water bottles, milk sachets, and corrugated boxes demonstrate the product’s strength, shape retention, and environmental benefits. ALS-based packaging products are fully biodegradable within 60 to 90 days, leaving no toxic residues or microplastics, thereby reducing plastic waste, supporting sustainable agricultural practices, and offering a commercially viable alternative to plastic packaging.
