Heavy duty corrugated box is widely used in daily life, not only has the function of beautifying and publicizing goods, but also can protect goods, facilitate transportation and storage. It belongs to green environmental protection products, it is conducive to environmental protection, loading and unloading transportation. Whether it is heavy corrugated box or corrugated board, after a long time of use, there will be softening problem, which will have a bad impact on the normal use, and also produce the corresponding waste. Generally, the softening of heavy corrugated box is due to the problem of moisture. The following is the reason for the softening problem of heavy corrugated box manufacturers and the relevant solutions.

一、天气影响因素、梅雨湿润天气和环境湿度高会导致波纹纸箱变软，建议从波纹纸箱储存工作环境方面出发解决我们这一问题。

1、 Weather factors, wet weather in Meiyu and high humidity will lead to the softening of corrugated cartons. It is suggested to solve this problem from the storage and working environment of corrugated cartons.

二、波纹纸箱本身材料存在问题，波纹原纸和波纹纸板材料较差，易于吸收水，波纹纸箱和纸板自然柔软，然后一般更换高质量的坑纸，现在有坑纸含有防水剂，可有效减少或减少一些波纹纸箱回软现象。

2、 Corrugated paper and corrugated paperboard materials are poor, easy to absorb water, corrugated paper and paperboard are naturally soft, and then generally replace high-quality pit paper. Now pit paper contains waterproof agent, which can effectively reduce or reduce the softening phenomenon of some corrugated boxes.
                

三、改进企业生产技术工艺，我们一般在瓦楞包装纸箱上加防水剂，在生产线上做预热、上浆、烘干等处理工序。在制作的同时增加蹦床的含量，加入防水添加剂，有效降重型瓦楞纸箱的柔软度。

3、 To improve the production technology of enterprises, we usually add waterproof agent on corrugated packaging cartons, and do preheating, sizing, drying and other processing procedures on the production line. At the same time, the content of trampoline is increased and waterproof additives are added to effectively reduce the softness of heavy corrugated box.

储存环境也是一个重要的因素。重型瓦楞纸箱一般存放在干燥地面的通风仓库中，用薄膜缠绕薄膜保护。而且对于我们的地板也用木垫，因为木垫可以通过吸收利用地面的湿气。而且重型瓦楞纸箱厂家的储存环境要通风，让空气流通，可以减少重型瓦楞纸箱的回软。

Storage environment is also an important factor. Heavy duty corrugated boxes are usually stored in ventilated warehouse on dry ground and protected by film winding. And for our floor, we also use wooden mats, because wooden mats can absorb and utilize the moisture of the ground. And the storage environment of heavy corrugated box manufacturers should be ventilated, so that the air circulation can reduce the softening of heavy corrugated box.

总而言之，重型瓦楞纸箱回软的问题，归根结还是企业存在大量水份以及管理研究问题。只有在原纸储存、瓦楞纸板加工、纸箱生产加工、仓储运输等过程中尽量避免纸箱吸湿，才能硬化。以上就是重型瓦楞纸箱的回软问题与解决方案,想了解更多内容可以多关注我们!

In a word, the soft problem of heavy corrugated box, in the final analysis, is that there is a lot of water in the enterprise and management research problems. Only in the process of base paper storage, corrugated board processing, carton production and processing, storage and transportation, try to avoid moisture absorption of cartons, in order to harden. The above is the heavy corrugated box back to soft problems and solutions, want to know more can pay more attention to us!
