Abstract: ABSTRACT J Title: ECO-FRIENDLY BIOPOLYMER FILM FROM MULBERRY BARK CELLULOSE I 10 This invention relates to an eco-friendly biopolymer film from mulberry bark cellulose. It typically includes a Raw Material (1), an Alkaline Solution (2), a Bleaching Agent (3), an Acid Solution (4), a Distilled Water (5), a Solvent (6), a Plasticizer (7), a Homogenizing Equipment (8), a Casting Surface (9), and a Drying Apparatus (10). This invention provides a sustainable, cost- effective, and fully biodegradable alternative to synthetic plastics by converting underutilized sericulture waste into a high-performance, non-toxic biopolymer film. This versatile biopolymer film serves as an eco-friendly material for sustainable food packaging, biodegradable agricultural mulch, biomedical wound dressings, and controlled-release drug delivery systems. 15 Figure 1. Shows the process flow diagram for creating a biopolymer film from mulberry bark involves several chemical and mechanical steps to extract and refine cellulose.
