Description

瓦楞纸板型包装材料
技术领域
本发明涉及一种瓦楞纸板型包装材料。
背景技术
已知的瓦楞纸板的制造包括一层平面纸层。一种瓦楞辅助纸层被胶粘到平面纸层上，且所述辅助纸层的波纹的波幅垂直于包装材料的伸展方向。所有的脊被布置成直线平行波纹。然而，问题在于，在材料中形成褶皱线时，作为沿着特定线的褶皱，存在相对于邻近的谷交错的趋势。另外，在平面纸层上借助光栅(raster)进行的打印会由于洗衣板效果而被隐蔽，与脊相对的打印色彩和与波相对的色彩相比会发生色调的细微差别。另外，平行于波的抗扯强度较弱。材料的硬度和吸收撞击的能力并不十分理想，且所述材料的硬度也不够。

Figure C0380855900041
US-A-4012276公开了一种包装材料，具有两层不同类型的辅助瓦楞状层，不同类型的所述层之间存在一波相移。
发明内容
本发明的目的是提供一种上述类型的包装材料，其较迄今公知的材料更适合于进行打印，且较迄今公知的材料更硬，且表现改进的抗扯强度。
根据本发明的包装材料，其特征在于所述的包装材料包括一个第一平面纸层、一个安排成第一平面纸层之下的一个第一辅助纸层，一个在第一辅助纸层下的第二平面纸层和在第二平面纸层下的第二辅助纸层，并且在这些波纹之间具有一小的相位位移，所述的波纹的波幅与所述的两个辅助纸层的伸展方向垂直。两层辅助瓦楞状层为相同类型。结果是，所述包装材料变得较迄今公知的材料更硬。即抗挠刚性更好，且不影响材料的轻巧性和容积度。这种波纹的折叠需要相当大的力。另外，所述材料被证明非常适合印刷。抗扯强度被增加，因为沿着波纹撕扯材料的可能性被降低。折叠线非常清楚，因为它们总是跨过一些脊延伸。
根据本发明，所述平面纸层和辅助纸层可以是相同的厚度，优选是在0.05和0.3mm之间，且优选的是约0.1mm，所述辅助纸层可以是例如克重为50到250g/m2，特别是70到150g/m2。所获得的包装材料非常耐用。
此外，在根据本发明的包装材料中，一种淀粉基胶或冷水胶可被用于进行所述层的层叠。这种包装材料被证明表现高粘合力和长耐久性。
根据本发明，所述辅助纸层的表面可以沿着一个表面，该表面基本上符合以下数学函数式：
z ( x , y ) = a sin ( 2 π λ 1 x + π 2 + b sin 2 π λ 2 y )
其中a和λ1分别表示垂直于辅助纸层的伸展平面的波纹的波幅和波长，且其中b和λ2分别表示在所述辅助纸层的平面中的波纹的波幅和波长。两种类型的波纹的波幅的比率
Figure C0380855900052
可以在0.10到0.60的范围内，优选的是在0.15到0.50的范围内，特别是对应于a＝0.5mm和b＝2.25mm时的0.22。该包装材料的实施例被证明是特别硬且适合于大件分离家具部件和板的运输。
另外，根据本发明的两种类型的波纹的波长的比例 可以在0.09到0.20的范围内，优选的是对应于λ1＝3.5mm和λ2＝23.5mm时为0.15。这已经被证明是特别有利的。
最后，根据本发明的至少一种类型的波纹在侧面上是相当平坦的，所述波纹大致上呈锯齿形状，其中所述脊和槽稍微呈圆形，或者所述波纹可以基本上是方形。结果是，能够使辅助纸层的制造更便宜，因为，用于将辅助纸层压成形状的压制工具可以以较迄今公知的工具更低的价格制造。
附图说明
下面将参照附图对本发明进行详细解释，其中
图1为按照本发明的包装材料的一部分的透视图，在呈现垂直于第一辅助纸层的波幅的波纹和呈现垂直于第二辅助纸层的波纹之间存在一小相移，以及
图2示出了一种理想的辅助纸层的波纹的实施例的XYZ-坐标系，
具体实施方式
如图1所示的包装材料的部分由一种层叠片构成，该层叠片包括一层平面纸层11和一层设置在所述层11之下的辅助纸层12。在所述辅助层12之下设置有一层第二平面纸层13。在后者之下设置第二辅助纸层14和可选择的第三平面纸层。所述辅助纸层包括呈现垂直于辅助纸层的伸展平面即沿着平行于箭头A的方向的波幅a的波纹。这些波纹的波峰在辅助纸层12和14中形成一个呈现在辅助纸层的伸展平面中的波幅b的基本上平行的波体系。后者的波纹也可以被成为平行振荡。
平面纸层11和13与辅助纸层12和14可以是相同的厚度，优选是在0.05和0.3mm之间，例如0.1mm。每层辅助纸层的克重可以是例如50到250g/m2，优选是70到150g/m2。
一种胶，例如淀粉基胶或冷水胶，可被用于所述层的层叠。
如图2所示，所述辅助纸层12和14的每个表面可以沿着一个表面，该平面基本上符合以下数学函数式：
z ( x , y ) = a sin ( 2 π λ 1 x + π 2 + b sin 2 π λ 2 y )
其中a和λ1分别表示垂直于每个辅助纸层13的伸展平面的波的波幅和波长，且其中b和λ2分别表示由上述波纹的波峰构成的且呈现所述辅助纸层12或14的平面中的波幅的波纹的波幅和波长。所述函数式适用于直角XYZ-坐标系。
两种类型的波纹的波幅的比率
Figure C0380855900071
可以在0.10到0.60的范围内，优选的是在0.15到0.50的范围内，特别是对应于a＝0.5mm和b＝2.25mm时的0.22。
两种类型的波纹的波长的比例
Figure C0380855900072
可以在0.09到0.20的范围内，优选的是对应于λ1＝3.5mm和λ2＝23.5mm时的0.15。
就呈现垂直于辅助纸层12和14的伸展方向的波幅a的波纹而言，参照图1，一小相移被设置在这些层的波纹之间，且的范围为平面纸层15是可选择的。
在辅助纸层12和14中，至少呈现垂直于包装材料的伸展平面的波幅的波纹可以被设置成相当扁平的侧面，即所述波纹基本上为锯齿状。所述锯齿形状可具有稍微呈圆形的顶面和底面，即，三角形波。
呈现垂直于包装材料的伸展平面的波幅的波纹也可以基本上呈方形波形。
根据本发明的包装材料的优点在于展现高抗挠刚度和较高的吸收撞击的能力。另外，所述材料呈现高抗扯强度，因为，材料被沿着波纹撕碎的可能性已经被大大降低或消除。此外，所述材料优选地包括折叠线，所述折叠线总是清楚的，因为它们总是连续地跨过脊，这对于物品的机械包装来说是一个重要特征。洗衣板效果被最小化。此外，所述材料非常适于进行图形打印。所述材料被证明特别适合于包装平面家具部件。最后，应当注意，由于根据本发明的包装材料的应用能够改善包装机械，因此能够使包装机械的应用以更加有效的方式进行。
当然，每种纸层的克重可以为克每m2，其与每单层辅助纸层的克重克每m2不同。
在不背离本发明的范围的情况下，本发明可以以许多方式被改变。
