Чому гофрокартонні коробки розм'якшуються?

In our daily lives, we often notice that corrugated cardboard boxes tend to soften over time. Why does this happen? Here’s an explanation from Reding Packaging:

1. Weather Factors
   Humid weather, such as during the rainy season, and environments with high humidity can cause corrugated boxes to soften. To prevent this, it’s recommended to address the storage environment of the boxes.
2. Production Process Improvements
   During production, adding water-repellent agents to the cardboard helps reduce the chances of softening. The production process should also include preheating, gluing, and drying steps. Increasing the amount of borax during the gluing stage and adding waterproof additives can further minimize the softening of corrugated boxes.
3. Material Quality
   Poor-quality raw materials, such as low-grade paper or corrugated board, tend to absorb moisture easily, making the boxes softer. Using higher-strength corrugated paper with better quality can help. Some types of corrugated paper even contain water-repellent agents, which can significantly reduce the softening issue.
4. Storage Environment
   The storage environment plays a crucial role in preventing softening. It’s essential to store the boxes in well-ventilated, dry warehouses. Use stretch film for additional protection and wooden pallets to absorb moisture from the ground. Ensuring proper airflow and ventilation in the storage area can greatly reduce the chances of corrugated boxes softening.

By taking these steps, the risk of corrugated cardboard boxes softening can be significantly reduced, ensuring their strength and durability.
