At present, the new structure honeycomb paperboard adopts the modern bionics principle, and uses kraft paper as raw material to be made by special techniques and equipment.

Its characteristics:

The bearing capacity of the 10mm thick honeycomb paperboard is 0.5 tons/m2, which is 2-10 times that of the five-layer corrugated board.

The elasticity is good, because the density of the honeycomb honeycomb core structure is different, which makes the elastic range large and produces strong earthquake resistance.

High strength, strong pressure resistance and folding resistance. The compressive strength of 10mm thick honeycomb paperboard is 2-75.6 times that of five-layer corrugated board; the flexural strength is twice the transverse strength of five-layer corrugated board, longitudinal 29.2 times.

Lightweight, 1 square meter thicker than 5.1mm thick five-layer corrugated paper can make 1.44m2 of l0mm thick honeycomb paperboard. It weighs only 2/3 of corrugated board of the same specification and 1/3 of wood.

The cost is low, because the honeycomb paperboard is less than the raw material of the corrugated paperboard, and the honeycomb paper core is produced by the low-cost kraft paper; the material cost is only 2/3 of the corrugated board and 1/3 of the wooden board.

Due to macro-control and resource shortages, the paper industry and the packaging industry are constrained by the state's restrictions on timber deforestation. The supply of raw materials is in short supply. It is necessary to seek packaging materials based on paper and wood, and replace the traditional corrugated paper with new structural honeycomb paperboard that saves wood. The industrial policy of wood packaging has reached more than 70% in foreign countries.

In response, the state has proposed to accelerate the development and promotion of honeycomb paperboard, and gradually replace some wood packaging. After more than 10 years of research and development, China's honeycomb paperboard production technology and market development continue to make progress. The domestic honeycomb paperboard production line has developed the fifth and sixth generation production special equipment. According to incomplete statistics, there are currently about 150 honeycomb paperboard equipment and product manufacturing enterprises in China. There are nearly 20 in Jiangsu Province and nearly 10 in Shanghai.
