再造烟叶片基加香涂布技术在卷烟包装中的应用

Application of flavoring coating technology of reconstituted tobacco base-sheet to cigarette packaging

为了解不同定量对造纸法再造烟叶片基性能的影响,通过在抄造过程中改变片基定量的方式,研究了再造烟叶片基定量对其物理性能、渗透性能和微观结构的影响,对优选出的定量为180g/m^2的片基进行涂布加香、激光雕刻后应用到卷烟包装中。结果表明:①片基的定量从60g/m^2增加到240g/m^2,片基的抗张指数、抗张强度、挺度逐渐增加,片基的表面性能得到明显改善,片基的内部会形成更多的孔隙,利于片基对液体的吸收与渗透。②优选出定量为180g/m^2的片基较适宜的加香涂布量为40g/m^2,涂布加香后的片基经激光雕刻后应用到罐装卷烟的盖板中,卷烟的包装档次和开包香韵得到明显提升。

In order to investigate the relationships between grammage and physical properties of base-sheet of papermaking process reconstituted tobacco, the physical properties, permeability and microstructure of the base-sheet were tested via changing the grammage of base-sheet in the paper-making process. The 180 g/m^2 base-sheet was selected and applied to cigarette packaging after the processes of flavoring coating and laser engraving. The test results indicated that: 1)When the grammage increased from 60 to 240 g/m^2, the tensile index, tensile strength and stiffness of base-sheet increased gradually, the surface quality of base-sheet improved obviously, meantime, more pores formed inside the base-sheet, it was beneficial to its absorption to liquid. 2)The optimal flavoring coating rate for the selected 180 g/m^2 base-sheet was 40 g/m^2, the flavoring coated base-sheet was engraved by laser, then used as a cover liner of cigarette tin to promote the luxurious tastes of the contents and offer an additional open aroma.
