In our daily life, we often find that corrugated cardboard boxes have a softening phenomenon. Why is this? Here is the answer for you:
1. Weather factors such as rainy and humid weather, as well as high environmental humidity, can cause corrugated cardboard boxes to soften. It is recommended to start with the storage environment of corrugated cardboard boxes to solve this problem.
2. To improve the production process, we usually add waterproofing agents to corrugated cardboard boxes and perform preheating, gluing, and drying processes on the production line. And increase the content of sandpaper during the paste making process, add waterproof additives, and reduce the probability of corrugated cardboard boxes softening.
3. The material problem of corrugated cardboard boxes themselves is that the raw paper and corrugated cardboard materials of corrugated cardboard boxes are poor, which makes them easy to absorb water. The corrugated cardboard boxes and cardboard naturally become soft, so it is necessary to replace them with high-strength and high-quality pit paper. Currently, there is a type of pit paper that contains waterproofing agents, which can reduce or minimize the phenomenon of some corrugated cardboard boxes becoming soft.
4. The storage environment is also a very important factor. Corrugated cardboard boxes are usually stored in ventilated and dry warehouses, and wrapped with wrapping film for external protection. It is recommended to use wooden pads as they can absorb moisture from the ground. The storage environment should be well ventilated to allow air circulation, which can reduce the softening phenomenon of corrugated cardboard boxes.
