| 摘要: |
| 目的 探索涂层技术在白牛皮纸上的应用，提高白牛皮纸的阻湿和抑菌杀菌性能，拓宽其包装应用范围。方法 先筛选涂布液的原料，再调剂它们的相容性。采用刮刀对纸张进行涂布，接着在涂层面覆膜，加热吹风并辊压后揭膜，在白牛皮纸表面形成厚度均匀的涂层。干燥后测试其抑菌杀菌性、阻湿性、力学强度及光泽度等指标，并分析其市场应用及商业价值。结果 涂布后白牛皮纸的阻湿性提高了4~5倍;抑菌杀菌性能随着壳聚糖含量的提高而提高，最高可达15倍;光泽度随着明胶含量的提高而提高。结论 天然可降解涂层有效提升了白牛皮纸的抑菌杀菌性、阻湿性等，提升了纸面的光泽度和美观度等商业价值。 |

| Abstract: |
| The work aims to explore the application of coating technology on the white kraft paper, improve its moisture resistance, antibacterial and bactericidal properties, and expand its application in packaging. Firstly, raw materials for the coating solution were selected, then their compatibility adjusted. And a scraper was used to coat the paper to obtain a uniformly thick coating. After drying, its antibacterial and bactericidal properties, moisture resistance, mechanical strength, and glossiness were tested, and its application and commercial value data were analyzed. The moisture resistance of the coated white kraft paper increased by 4-5 times, and the antibacterial and bactericidal properties increased with the increase of chitosan content, reaching a maximum of 15 times. The glossiness also increased with the increase of gelatin content. The natural biodegradable coating effectively enhances the antibacterial and bactericidal properties and moisture resistance of white kraft paper, and improves the commercial value of paper surface gloss and aesthetics. |
