METHOD FOR APPLYING REGISTER MARKS TO WRAPPING PAPER FOR SMOKING ARTICLES

The invention relates to a method for marking a wrapping paper for smoking articles， comprising the following steps: (A) providing a wrapping paper for smoking articles， the wrapping paper comprising pulp fibers， and (B) producing markings on the wrapping paper by means of at least one of the following steps: (B.1) removing material from the wrapping paper， (B.2) mechanically changing the wrapping paper， (B.3) treating the surface of the wrapping paper with laser radiation having an energy density y in J-m-2， to which the following applies: y = k - x. x is the enthalpy of combustion per volume of the wrapping paper in J-m-2μm-1， and k is at least -8 μm， preferably at least -7 μm and especially preferably at least -6. μm， and at most -1 μm， preferably at most -2 μm and especially preferably at most -2.5 μm. Either repeating structures are produced on the wrapping paper in a step (C) such that each structure is at a fixed distance in the machine direction relative to at least one marking， or in step (A) a wrapping paper is provided which has repeating structures in the machine direction， and the markings are produced on the wrapping paper in step (B) in such a way that each marking is at a fixed distance in the machine direction relative to at least one structure.

本发明涉及一种吸烟制品包装纸的标记方法，包括如下步骤：(A)提供一种吸烟制品包装纸，所述包装纸包含纸浆纤维；(B)通过以下至少一种步骤在所述包装纸上形成标记：(B.1)从包装纸上去除材料；(B.2)对包装纸进行机械改性；(B.3)采用能量密度为y（单位：J·m⁻²）的激光辐照处理包装纸表面，其中y满足关系式：y = k - x。其中x为包装纸单位体积的燃烧焓（单位：J·m⁻²·μm⁻¹），k的取值不小于-8 μm，优选不小于-7 μm，特别优选不小于-6 μm；且不大于-1 μm，优选不大于-2 μm，特别优选不大于-2.5 μm。可采用以下两种实施方式之一：在步骤(C)中于包装纸上形成重复结构，使得每个结构在纵向（machine direction）上与至少一个标记保持固定间距；或在步骤(A)中提供一种在纵向（machine direction）上具有重复结构的包装纸，并在步骤(B)中于包装纸上形成标记，使得每个标记在纵向（machine direction）上与至少一个结构保持固定间距。本发明涉及一种吸烟制品包装纸的标记方法，包括如下步骤：(A)提供一种吸烟制品包装纸，所述包装纸包含纸浆纤维；(B)通过以下至少一种步骤在所述包装纸上形成标记：(B.1)从包装纸上去除材料；(B.2)对包装纸进行机械改性；(B.3)采用能量密度为y（单位：J·m⁻²）的激光辐照处理包装纸表面，其中y满足关系式：y = k - x。其中x为包装纸单位体积的燃烧焓（单位：J·m⁻²·μm⁻¹），k的取值不小于-8 μm，优选不小于-7 μm，特别优选不小于-6 μm；且不大于-1 μm，优选不大于-2 μm，特别优选不大于-2.5 μm。可采用以下两种实施方式之一：在步骤(C)中于包装纸上形成重复结构，使得每个结构在纵向（machine direction）上与至少一个标记保持固定间距；或在步骤(A)中提供一种在纵向（machine direction）上具有重复结构的包装纸，并在步骤(B)中于包装纸上形成标记，使得每个标记在纵向（machine direction）上与至少一个结构保持固定间距。
