Several fully green composites are prepared by taking the tea polyphenols (TP) with various percentages to blend with poly(vinyl alcohol) (PVA). The as‐prepared PVA/TP composite with only 5% TP shows superb anti‐UV properties even after water washing, the presented UV protection factor (UPF) value is still greater than that of the standard values reported by Australia and New Zealand (AS/NZS 4399‐1996). Moreover, the UPF value of those PVA/TP composites is found capable of furthermore enhancement by increasing the TP percent. This PVA/TP composite also shows good antibacterial and biodegradability while it is kept with certain mechanical properties to fit required application cases.
