Abstract The applicability of making a gift-wrapping paper fragrant by screen-printing with a varnish that contained microencapsulated fragrance were assessed. Experiments were conducted on a commercially available, general use, Lavender (Lavandula Angustifolia) essential oil. The encapsulation was made by a complex coacervating technique, with gelatin and gum-arabic as the wall materials. Factors in the encapsulating process were studied with the attempts to control the strength, the release and the morphologies of microcapsule. The statistical tools including the analysis of variance, the main effect plot, and the rolled throughput yield were used in identifying the controlling factors and the best performing conditions for encapsulation. Fragrant varnishes made by mixing the microcapsule into a commercially available UV-curable varnish were evaluated and optimized for the essential oil loading capacity, the release by rubbing with fingers, the protection against untimely release, and the load withstanding in handling, storage and transportation. All the practices specifically required to produce a fragrant gift-wrapping paper were done without the need to modify or to interfere with the actual screen-printing process. The overall results signified its potential in applications like special ordered or customized, small volume gift-wrapping papers, and the likes.

包封薰衣草精油在明胶/树胶-阿拉伯复合凝聚层和清漆丝网印刷中在制作香型礼品包装纸中的应用

摘要 评价了用含微胶囊香料的清漆丝网印刷制作香味礼品包装纸的适用性。对市售的通用薰衣草 (Lavandula Angustifolia) 精油进行了实验。胶囊是通过复杂的凝聚技术制成的，以明胶和阿拉伯树胶为壁材。研究了封装过程中的因素，试图控制微胶囊的强度、释放和形态。统计工具包括方差分析、主效应图和轧制吞吐量，用于确定控制因素和最佳封装条件。通过将微胶囊混合到市售的紫外线固化清漆中制成的芳香清漆在精油负载能力、手指摩擦释放、防止过早释放以及处理、储存和运输中的负载承受能力方面进行了评估和优化。生产芬芳的礼品包装纸所需的所有操作均已完成，无需修改或干扰实际的丝网印刷过程。总体结果表明其在特殊订购或定制、小体积礼品包装纸等应用中的潜力。生产芬芳的礼品包装纸所需的所有操作均无需修改或干扰实际的丝网印刷过程。总体结果表明其在特殊订购或定制、小体积礼品包装纸等应用中的潜力。生产芬芳的礼品包装纸所需的所有操作均已完成，无需修改或干扰实际的丝网印刷过程。总体结果表明其在特殊订购或定制、小体积礼品包装纸等应用中的潜力。
