之前我们文章提到过“蔬菜包装纸箱抗压的决定因素是什么？”，今天重型纸箱厂家带我们来了解一下“重型纸箱为什么会出现变形？如何处理？”。虽然重型瓦楞纸箱相对抵抗压力和磨损,但毕竟是一盒,即使在运输过程中不受外界损伤的影响,这是不可避免的,因为长期储存的软崩溃,变形等现象。在生活中，什么会成为瓦楞纸箱变形重的原因?
As mentioned in our previous article, "what are the determinants of the compression resistance of vegetable packaging cartons?" Today, heavy cartons manufacturers take us to understand "why do heavy cartons deform? How to deal with it? ". Although the heavy-duty corrugated box is relatively resistant to pressure and wear, it is a box after all. Even if it is not affected by external damage during transportation, it is inevitable because of the soft collapse and deformation of long-term storage. In life, what will become the cause of heavy deformation of corrugated boxes?
重型瓦楞纸箱箱体变形的常见原因及处理方案
The common causes of the deformation of the heavy corrugated box and the treatment plan1.如果硬纸板含水量过多，就会导致硬纸板的硬度大大降低，还会影响硬纸板的边缘压力。
1. If there is too much water in the cardboard, the hardness of the cardboard will be greatly reduced, and the edge pressure of the cardboard will also be affected.
2.重型瓦楞纸箱的外形。瓦楞的形状有U形、V形和UV形。U型瓦楞纸具有良好的弹性，高的延伸性和吸收性，但强度不稳定。v型瓦楞附着力差，易剥落和分离，但强度高。通常建议使用UV表单，正如其名称所暗示的那样，将U和V表单的优点结合在一起。
2. Shape of heavy corrugated box. The shapes of corrugations are U-shaped, V-shaped and UV shaped. U-shaped corrugated paper has good elasticity, high extensibility and absorption, but its strength is not stable. V-type corrugated has poor adhesion, easy peeling and separation, but high strength. UV forms are generally recommended, as their names imply, to combine the advantages of u and V forms.
3.纸板粘合强度要大。瓦楞纸与面纸之间的相互粘接称为纸板粘接强度。如果出现假粘连的现象，其沉重的瓦楞纸箱的压缩程度也会下降，瓦楞纸板在压缩时会被层层分隔开来。
3. The bonding strength of paperboard shall be large. The mutual bonding between corrugated paper and face paper is called board bonding strength. If the phenomenon of false adhesion occurs, the compression degree of the heavy corrugated box will also decrease, and the corrugated board will be separated layer by layer during compression.
4.使厚瓦楞纸板的层数合理化。合理的层数设计可以提高纸箱本身的抗压性能，不合理的层数设计自然会增加纸箱的破损率。建议根据产品的包装、重量、储运条件、堆高、储存时间等特点，考虑设计板的层数。
4. Rationalize the layers of thick corrugated board. Reasonable layer design can improve the compression performance of the carton itself, and unreasonable layer design will naturally increase the damage rate of the carton. It is suggested to consider the number of layers of the design plate according to the characteristics of the product, such as packaging, weight, storage and transportation conditions, stacking height, storage time, etc.
5.在生产过程中，应注意控制纸箱与机器之间的压力。为了避免出现瓦楞坍塌、变形等情况，降低纸箱的受压程度。
5. In the production process, pay attention to control the pressure between the carton and the machine. In order to avoid corrugating collapse, deformation and other situations, reduce the compression degree of cartons.
常见的变形原因有重瓦楞纸箱和处理方案这些都是重型纸箱厂家小编通过材料查看整理出来的，如果你有更好的方法，欢迎指正!
