Overview

Develops bioplastic films using potato peel starch and PVA reinforced with black tea for packaging, indicating sustainable options for reducing plastic waste.

Key Points

  • This research aims to create eco-friendly bioplastic films by utilizing potato peel starch and PVA, reinforced with black tea waste extract.
  • Developed bioplastic films through solution casting of starch and PVA.
  • Used black tea waste extract at varying concentrations as reinforcement.
  • Evaluated films for mechanical, barrier, and structural properties using ASTM/ISO standards.
  • Characterized black tea waste extract using GC-MS to identify bioactive compounds.
  • Tensile strength improved from 8.35 MPa to 13.42 MPa with 2.0% BTWE.
  • Burst strength peaked at 3.95 kg/cm² with 1.0% BTWE, meeting commercial standards.
  • Water absorption minimized to 118.07% at 1.5% BTWE compared to 155.92% control.
  • Migration levels remained below 1.79 mg/dm², compliant with EU regulations.
