卷烟纸的制备按实施例一的生产过程。
常温下， 在涂布液调制桶中加入一定质量的碳酸钙作为填料， 配制成质量百分浓度为 50%的悬浊液， 搅拌均匀； 向其中加入质量百分浓度分别为 3%碱金属藻酸盐和 1%聚乙烯醇 作为粘度调节剂， 搅拌均匀后； 再向其中加入质量百分浓度分别为的 5%淀粉、 12%环糊精 和 18%麦芽糊精， 作为成膜剂， 搅拌均匀。 丝网印刷涂布带宽度为 6mm。
考察采用不同实施方案对卷烟纸主要物理指标的影响， 以未印刷涂布卷烟纸作为卷烟 原纸， 结果如表 1所示。
从表中结果可以看出，卷烟原纸经丝网印刷涂布后， 按不同实施例相比于卷烟原纸定 都增加 4克 /米 2， 而卷烟纸透气度根据不同实施例由原纸 80柯瑞斯塔 （单位： CU) 降 5〜20柯瑞斯塔； 各实施例对卷烟纸其他物理指标影响不大。

采用国内某出口牌号卷烟烟丝在相同条件下进行样品卷制， 以普通卷烟纸卷制样品作 为对照样， 按照低引燃卷烟 FASE 测试方法 （大气环境下烟支水平放置空烧） 和 ASTM E2187-04测试方法 （测试箱内特定滤纸基质上测试）， 测定对照样和实施例样品的引燃性 情况， 测试结果如表 2所示。

从测试结果可以看出， 各实施例添加涂布带后， 按 FASE测试方法， 熄火率非常低或不 熄火； 按 ASTM E2187-04测试方法， 熄火率都在 90%以上， 达到大于 75%熄火率的标准要 求， 具有低引燃倾向性效果。
对不同实施例低引燃型卷烟与对照卷烟样品在吸烟机上进行烟气分析测试， 测试结果 如表 3所示。

从表中烟气指标测试结果也可以看出， 通过卷烟原纸透气度调整不同实施例的低引燃 样品与对照样烟气指标变化幅度不大， 都符合卷烟盒标设计要求。
对低引燃型卷烟进行感官质量评吸，结果显示不同实施例样品相比于对照样都稍有剌 激性， 但对卷烟整体抽吸品质无明显负面影响， 由于低引燃型卷烟的特殊性， 因此我们只 要求在满足低引燃性设计前提下， 尽量保持对卷烟原有抽吸风味。
综上所述，本发明通过丝网印刷方式在卷烟纸上添加包含有成膜剂、粘度调节剂以及 填料的涂布带， 卷烟样品在满足大气环境下空烧不熄火， 而在可燃物基质上满足熄火要求 下， 对卷烟烟气指标影响较小， 而又不影响卷烟整体抽吸品质。
