Aimed at decreasing the environmental pollution caused by petroleum-derived packing materials, many efforts have been directed towards fabricating biodegradable substitutes, especially of cellulose-based film with functional properties. In this paper, a totally plant-derived antibacterial film was successfully prepared. Regenerated cellulose films were used as substrate and poacic acid, a decarboxylated product from 8–5-diferulic acid, as fungicides. The physical properties and thermal stability of the prepared plant-derived antibacterial films were characterized, and the antibacterial activity was also assessed as the function poacic acid contents. The morphology showed that the cellulose/poacic acid films exhibited a homogeneous and smooth surface and poacic acid was successfully incorporated into cellulose films as revealed by Fourier-transform infrared (FT-IR) spectroscopy and fluorescent microscopy. It was noted that both the tensile strength and thermal stability of the antibacterial films decreased due to the incorporation of the poacic acid. Remarkably, the prepared cellulose/poacic acid films exhibited superior antibacterial activity against Staphylococcus aureus. The notable properties of the cellulose/poacic acid films are promising for applications in food and medical packaging to enhance their safety.
