The results show that gooseberry peel can be used as a good film-forming precursor, and tea polyphenols and teak peel have great potential to prepare edible or biodegradable packaging films. Generally speaking, the PPF/TP composite membrane containing 10% TP has good oxidation resistance, antibacterial properties, mechanical properties and water resistance, which is relatively good in combination, because it provides stronger intermolecular bonds and more compact microstructure, showing the application potential as an alternative bio-active packaging material.
