MUMBAI, India, July 11 -- Intellectual Property India has published a patent application (202521047902 A) filed by Pimpri Chinchwad College Of Engineering; Mr. Sanjiwan K Bhoite; Dr. Falguni Bhavsar; Dr. Pranjal Jog; Shivraj Karle; and Hrushikesh Jog, Pune, India, on May 18, for 'biodegradable water packaging using a polylactic acid (pla)-polyhydroxybutyrate-valerate (phbv) blend.'
Inventor(s) include Mr. Sanjiwan K Bhoite; Dr. Falguni Bhavsar; Dr. Pranjal Jog; Shivraj Karle; and Hrushikesh Jog.
The application for the patent was published on July 11, under issue no. 28/2025.
According to the abstract released by the Intellectual Property India: "The present invention relates to a biodegradable water bottle composed of a polymer blend consisting of 70-85 wt% polylactic acid (PLA), 10-25 wt% poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), and 1-5 wt% maleic anhydride-grafted PLA (PLA-g-MAH). The blend is processed via injection stretch blow molding (ISBM) with optimized temperature and crystallinity to enhance mechanical strength and barrier performance. A dual-layer coating of carnauba and beeswax is applied to both interior and exterior surfaces, significantly reducing oxygen and moisture permeability. Experimental results demonstrate superior tensile strength, impact resistance, and barrier properties compared to conventional PLA and PET alternatives. The bottle is certified as both industrially and home compostable, fully degrading within 180 days. The invention offers a commercially viable, sustainable packaging solution compatible with existing PET production lines, effectively addressing key limitations of conventional bio-based plastics and reducing environmental impact. This integrated material and processing strategy presents a technically advanced and non-obvious improvement in biodegradable water packaging."
