瓦楞纸箱是由瓦楞纸板经模切、压痕、钉合或胶合而成。它是应用非常广泛的包装产品之一，其消费量一直居各类包装产品之首。瓦楞纸板若发生变形，将直接影响印刷、模切或开槽的质量。现在让我们有一个详细的了解。
Corrugated box is made of corrugated board by die cutting, indentation, nailing or gluing. It is one of the widely used packaging products, and its consumption has always been the first of all kinds of packaging products. If corrugated board is deformed, it will directly affect the quality of printing, die cutting or slotting. Now let's have a detailed understanding.
瓦楞纸板的变形，大致分为三种：纵拱、横拱和任意拱。
Corrugated board deformation, roughly divided into three types: longitudinal arch, transverse arch and arbitrary arch.
纵向拱是指沿生产线速度方向产生的拱；横向拱是指沿瓦楞方向产生的拱；任意拱是指沿任何方向产生的拱。面纸的表面称为正拱，内纸的表面称为负拱，面纸和内纸的表面称为正拱和负拱。
Longitudinal arch refers to the arch generated along the speed direction of the production line; Transverse arch refers to the arch generated along the corrugating direction; Any arch is an arch produced in any direction. The surface of face paper is called positive arch, the surface of inner paper is called negative arch, and the surface of face paper and inner paper is called positive arch and negative arch.
瓦楞纸板变形后，在双色印刷或多色印刷时，容易产生套色不准确、上墨不均、色边间隙大等问题。同时，它会使印刷开槽机开槽尺寸位移，纸箱上下摆动盖重分或不合缝，模切送料也会产生卡滞和尺寸位移等缺点，可能导致纸板正面损坏或设备损坏而被迫停止整理，使送料不便，并造成生产过程中，纸箱浪费增加。
Corrugated board deformation, in two-color printing or multi-color printing, easy to produce color registration is not accurate, uneven ink, color gap and other issues. At the same time, it will make the printing slotting machine slotting size displacement, carton up and down swing cover re split or not seam, die-cutting feeding will also produce stagnation and size displacement and other shortcomings, may lead to cardboard front damage or equipment damage and forced to stop finishing, so that feeding inconvenience, and cause production process, carton waste increase.
