本发明还公开了用于制造这样的预先切割的多层包装材料的模切方法（die-cutting process，冲模切割工艺）。
定义
在本发明中，术语“预先切割（pre-cut）”、“切入（incised）”、“切开（slit）”，“预先切开（pre-slit）”或者“刻划（scored）”具有相同的含义。
进一步地，在本发明中，术语“多层材料（multilayer material）”以其一般意义被采用并且包括具有纸质或者铝质的层压结构（laminate，层压制品），单层聚合物膜，该单层聚合物膜包括至少一个额外层，诸如印刷层、底漆层、粘合/密封层-例如冷封（CS）或者释放漆（RL）。
现有技术
预先切割的多层材料对于包装领域的技术人员而言是公知的。然而，现有技术中的多层材料一般表现出限制于一层的预先切割。通过对若干个预先切割的单层的层压来获得的叠加预先切割单层的多层材料在本领域也是已知的。
EP 1 817 165公开了一种多层膜，其包括多个连续、平行、并排的切口，以便于破坏载荷的减少，所述切口部分地影响最为刚硬层的厚度并且是通过去除材料而获得。
US5,312,659公开了一种层压膜包，其中聚烯烃树脂膜具有呈现大约膜厚度5%深度的划痕线。再次在这个情况中，仅有一层被刻划。
US4,903,841公开了一种层压片形成的袋，热密封的塑料层的一侧具有表面粗糙的区域，以方便包装的撕裂。再一次，仅有一层被预先切开。
US2005/0084636-A1公开了一种柔性的多层包装，其包括撕裂启动区以及定向的撕裂区域。在这个情况中，多层膜中仅有一层被刻划，基本上通过激光刻划。
