Paper boxes occupy an unnegligible position in the field of packing boxes, and honeycomb paper boxes are more often used by people. In fact, the honeycomb paper packaging box has been developed in China for many years, but in recent years it has become somewhat incompetent. Today, Xiao Bian came to analyze the reasons.
First, honeycomb paper boxes are prone to moisture. Honeycomb core paper, like corrugated paper, is made from recycled paper and is therefore relatively easy to absorb moisture and moisture. Honeycomb core paper uses a multi-layered core paper to separate and glue the dislocations, and it is combined with the paper to use glue on the core paper. The amount of glue in the production process is very large. There is a lot of water in the glue. After the paper is pasted on the paper, a closed space is formed, and too much moisture is not easily emitted. At the same time, a large amount of glue paste will be added during the process of splicing the cut honeycomb paperboard into products. In the manufacture of honeycomb paperboard, manufacturers often shorten the drying time to reduce energy consumption, and use natural air drying in the forming stage of products. When the weather conditions are not good or the shipment is urgent, the finished product often fails to meet the required moisture content standards, and the performance does not meet the requirements.
Second, the post-processing efficiency of honeycomb paperboard is low. Compared with foreign developed countries, there is a large gap between the integrity and automation of domestic cellular production lines. In the production process, there are many manual operations, especially the post-processing of honeycomb products. The tactics of the sea are often adopted, and the efficiency is low. The equipment and tools are simple.
Third, honeycomb paperboard packaging has poor resistance to multiple impacts. As we all know, the flat compressive strength is the strength of honeycomb paperboard. If the impact of the honeycomb paperboard package exceeds its flat compressive strength, a cushioning effect is produced by deformation of the core paper. This deformation is non-linear and irreversible. EPE, EPS and other buffer materials can absorb energy through self-deformation. External force withdrawal can rebound. The impact resistance of honeycomb paperboard is relatively poor. When a large deformation buffer occurs, the honeycomb core paper will be crushed and the noodle paper will break. The resistance to impact is basically only once.
I hope that the above information will help everyone. It is also hoped that there will be more technological innovations in the box field to solve these problems as soon as possible.
