Abstract: PVA/ST/IBE antibacterial composite films were synthesized from blending of polyvinyl alcohol
(PVA), starch (ST) and Impatiens balsamina extract (IBE), characterized by FTIR, XRD, SEM and TG for
analyses on morphology and structure, and further evaluated for mechanical, optical, barrier and
antibacterial properties. The characterization results showed that IBE was well combined with PVA/ST base
film. The PVA/ST/IBE composite films obtained exibited good antibacterial activity against Escherichia
coli, Staphylococcus albus and Bacillus subtilis, with the antibacterial performance improved with the
increase of IBE content. Meanwhile, the composite films displayed good mechanical strength and light
resistance. The tensile strength of the composite film with IBE additive amount of 12.50 mL [based on the
mass of PVA/ST base film (5 g), the same below] reached (22.97±0.68) MPa, the elongation at break
increased by 79.22% and transparency decreased by 11.90% compared with those of the PVA/ST base film.
PVA/ST/IBE antibacterial composite film showed good oxygen barrier performance, with a oxygen
