Enhancing the flexibility of polyvinyl alcohol/Uncaria gambir extract/boric acid biopolymer films via prolonged water immersion post-treatment
Polyvinyl alcohol (PVA) films mixed with boric acid (BA) and Uncaria gambir (UG) offer excellent UV shielding and moisture resistance but suffer from brittleness. This study introduces a water immersion technique to improve flexibility. The untreated film showed high tensile strength (57.7 MPa) and...
