瓦楞纸箱已经成为当今包装中使用最广泛的包装容器。无论是生产还是生活材料，无论是运输包装还是销售包装，瓦楞纸箱都起着重要的作用。瓦楞纸箱的抗压强度主要取决于右侧瓦楞纸板的侧压强度，粘合强度和纸箱结构。另外，它还受箱子的形状，生产工艺，印刷，环境温度和湿度等因素的影响。其中，环境湿度对瓦楞纸箱强度的影响更为明显。Corrugated boxes have become the most widely used packaging containers in today's packaging. Whether it is production or living materials, whether it is transport packaging or sales packaging, corrugated boxes play an important role. The compressive strength of the corrugated box is mainly determined by the side pressure strength, adhesive strength and box structure of the right corrugated board. In addition, it is subject to the shape of the box, production process, printing, ambient temperature and humidity and other factors. Among them, the influence of environmental humidity on the strength of corrugated box is more prominent.

瓦楞纸板在不同湿度条件下有着不同的机械性能：Mechanical properties of corrugated board under different humidity conditions:1，环境相对湿度越低，瓦楞纸板的穿刺强度越小，这是因为纸纤维在低湿度下会变脆;在高湿度范围内，环境湿度越大，穿刺强度越小，这是因为纸纤维在变湿之后变湿。松动并降低强度。1.The lower the relative humidity of the environment, the smaller the puncture strength of corrugated cardboard, which is because the paper fiber becomes brittle at low humidity; in the high humidity range, the greater the environmental humidity, the smaller the puncture strength, because the paper fiber becomes wet after it becomes wet. Loose and reduced strength.2，相对湿度对瓦楞纸箱边缘强度的影响随湿度的增加而减小。由于纸板的水分含量随着环境湿度的增加而增加，因此瓦楞纸板中的纤维素在吸收水分后逐渐变得疏松，并且瓦楞纸板的纸和芯纸的吸水率不同，导致承压过程。变形率不同。2.The effect of relative humidity on the edge strength of corrugated box decreases with increasing humidity. Because the moisture content of the paperboard increases with the increase of the environmental humidity, the cellulose in the corrugated cardboard gradually becomes loose after moisture absorption, and the moisture absorption rate of the paper and the core paper of the corrugated paperboard is different, resulting in the pressure bearing process. The deformation rate is different.

3.随着环境相对湿度的增加，瓦楞纸箱的粘合强度会大大降低。因为瓦楞纸板粘合粘合剂大多是水溶性淀粉基粘合剂。随着环境湿度的增加，粘合剂吸收的水分增加，粘度降低。瓦楞纸板的粘合强度的降低对瓦楞纸箱抗压强度的降低也具有更大的影响。3. The bond strength of corrugated box is significantly reduced as the relative humidity of the environment increases. Because corrugated board bonding adhesives are mostly water-soluble starch-based adhesives. As the ambient humidity increases, the amount of moisture absorbed by the binder increases and the viscosity decreases. The decrease in the bond strength of the corrugated board also has a greater impact on the reduction of the compressive strength of the corrugated box.
