Corrugated board is used to protect commodities. However, there are still various problems with various corrugated boards on the market.
[0003] When the current corrugated board is specifically applied, due to the characteristics of the paper, the waterproof performance of the surface of the corrugated board is relatively poor and it is very easy to get wet, making the corrugated board unable to be reused subsequently, thus reducing the environmental protection and energy-saving properties of the corrugated board. At the same time, it also reduces the service life and durability of the corrugated board. Currently, corrugated cartons cannot well protect the items inside the corrugated cartons, and it is easy to cause the items to be damaged, deformed or broken. Content of the Utility Model
