| 摘要: |
| 以季铵盐壳聚糖为抗菌剂处理普通成纸,制备了包装用抗菌纸。采用抑菌圈法评价了该抗菌纸对大肠杆菌和金黄色葡萄球菌的抑制效果,研究了季铵盐壳聚糖的浓度对抗菌纸厚度、抗张强度、耐破度和抑菌性能的影响。结果表明,抗菌纸的抗张强度及耐破度均较原纸有所增加,厚度没有明显变化,能满足包装需求,且具有良好的抗菌性能,其抗菌效果随季铵盐壳聚糖浓度的增加而增强,并且相同季铵盐壳聚糖浓度下的抗菌纸对金黄色葡萄球菌的抑菌效果要好于大肠杆菌。 |

| Abstract: |
| Antibacterial paper for packaging was prepared with quaternary ammonium salt of chitosan as antibacterial ingredients, and inhibition zone method was applied to evaluate its antibacterial effect on escherichiacoli and staphylococcus aureus. The effects of different concentration of quaternary ammonium salt of chitosan on thickness, tensile strength, bursting strength, and antibacterial property of the antibacterial paper were studied. The results showed that the strength tensile and bursting strength increase, but the thickness doesn't change significantly; the antibacterial paper can meet the requirement of packaging; the antibacterial effect of the antibacterial paper enhances with the increasing contents of quaternary ammonium salt of chitosan; the antibacterial performance of antibacterial paper is better on escherichiacoli than staphylococcus. |
