摘要： We prepared tea tree essential oil microcapsules, and the microcapsules and pullulan were coated on kraft paper to prepare an antibacterial paper. The antibacterial activity, structural characterization, and thermal stability of the prepared microcapsules and packaging paper were then tested. We found that the retention rate of microcapsules reached 87.1% after a 70 min of high-temperature treatment. The minimum inhibitory concentrations of microcapsules to S. aureus and E. coli were 112 mg/mL and 224 mg/mL, and the bacteriostatic zones of the packaging paper to E. coli and S. aureus were 17.49 mm and 22.75 mm, respectively. The prepared microcapsules were irregular. The paper coating was formed via hydrogen bonding, which filled the pores of paper fibers. When compared with the base paper, the roughness of the paper was reduced to 7.16 nm (Rq) and 5.61 nm (Ra), and no thermal decomposition occurred at <288 degrees C, which together implies a good application prospect.
