Abstract

The present study explored chitosan, a biodegradable nontoxic biopolymer, at different dosages for surface treatment of recycled paper to improve various properties relevant to packaging. Chitosan, at all applied concentrations, improved important paper properties like surface, strength and barrier due to which the low strength paper can also be used as a packaging paper. The effects of surface treatment of chitosan solutions of different concentrations on paper were analyzed by measuring breaking length, burst index, tear index, double fold, stiffness, air permeance, water vapor transmission rate (WVTR), wax pick, tensile energy absorption (TEA), and stretch. After surface treatment by 1% solution of chitosan, the breaking length, double fold, TEA, and stretch in machine direction were increased by 53.8%, 243%, 93%, and 75%, respectively, whereas burst index was increased by 38.4% in comparison with the base paper. The WVTR was reduced from 706 to 496 g/m²/24 h, and air passage time was increased from 18 to 65 Gurley s after surface treatment by 1% chitosan solution on the base paper. The chitosan solution at all the concentrations showed antibacterial activity in plate assay therefore reducing the susceptibility of paper to microbial attack.

不同浓度壳聚糖在再生纸表面的应用及其对包装性能的影响

壳聚糖是一种可生物降解的无毒生物聚合物，研究了壳聚糖在不同剂量下对再生纸进行表面处理，以改善与包装有关的各种性能。壳聚糖在任何浓度下都能改善纸张的重要性能，如表面、强度和阻隔性，因此这种低强度纸张也可以用作包装纸。通过测定不同浓度壳聚糖溶液的断裂长度、破裂指数、撕裂指数、折射率、硬度、透气性、水蒸气透过率(WVTR)、截蜡率、拉伸能吸收(TEA)和拉伸率，分析了不同浓度壳聚糖溶液对纸张表面处理的影响。经1%壳聚糖溶液表面处理后，与原纸相比，断裂长度、双折、TEA和机器方向拉伸分别提高了53.8%、243%、93%和75%，破裂指数提高了38.4%。经1%壳聚糖溶液对原纸进行表面处理后，WVTR由706 g/m2/24 h降至496 g/m2/24 h，空气通过时间由18 Gurley s增加到65 Gurley s。在平板实验中，壳聚糖溶液在所有浓度下均表现出抗菌活性，从而降低了纸张对微生物的敏感性。图形抽象
