Abstract

Antibacterial paper for packaging was sprayed by nanochitosan as antibacterial ingredients. The bacteriostatic circle method was adopted to evaluate its antibacterial effect on E.coli and Staphylococcus aureus. We investigated the effects of different concentrations of nanochitosan on antibacterial paper thickness, tensile strength, bursting strength, folding strength and antibacterial properties.The results showed that: tensile strength, bursting strength and folding strength of the antibacterial paper is better than the control paper and the thickness has no obvious change. The antibacterial paper enhanced the antibacterial effect following the increasing concentration of nanochitosan. The same concentration of nanochitosan antibacterial paper, its inhibitory effect on E.coli was greater than that of Staphylococcus aureus.
