In our daily life, corrugated boxes are often found to be soft. Why? Here's the answer:
1. Weather factors, rainy and humid weather and high ambient humidity will lead to the softening of corrugated boxes. It is suggested to solve this problem by starting with the storage environment of corrugated boxes.
2. For the improvement of production process, we usually add waterproof agent to the corrugated box, and the production line will conduct preheating, sizing, drying and other processes. In addition, the content of bouncing sand is increased during paste making, and waterproof additives are added to reduce the softening probability of corrugated boxes.
3. The corrugated box itself has material problems. The raw paper and corrugated board of the corrugated box are poor in material and easy to absorb water. The corrugated box and cardboard are naturally easy to become soft. The pit paper with high strength and high quality can be replaced. At present, there is a pit paper containing waterproof agent, which can reduce or reduce the softening of some corrugated boxes.
4. The storage environment is also a very important factor. Corrugated boxes are usually stored in a ventilated, dry warehouse on the ground, and wrapped with film for external protection. It is recommended to use wooden base plates, which can absorb moisture on the ground. The storage environment should be more ventilated to allow air circulation, so as to reduce the softening of corrugated boxes.
