ABSTRACT = {The current work explores the potential use of commercial Chinese bayberry tannin (BT) to develop antioxidant
PVA-based films using solvent casting process for packaging applications. The effect of BT concentration on opacity, water resistance and antioxidant capacity of resulting films was investigated. Properties like tensile strength,
thermal behavior, and morphological aspects were also characterized. The experimental results showed that
PVA/BT films formed with uniformly brown color and generally good transparency, offering good antioxidant
ability. The PVA film containing BT presented slightly higher water resistance according to the results of moisture
content and water vapor permeability, especially at low BT content (<10 wt%). The PVA can be compounded with
up to 10 wt% BT without any obvious deterioration in the tensile strength. The PVA/BT films exhibited better
thermal degradation behavior compared with PVA alone because of the chemical bonds of PVA-BT and the formation of char at high temperature. Based on the results, PVA incorporated with Chinese bayberry tannin may
provide broader formulation options for packaging materials with antioxidant action.},
