Honeycomb paperboard is an environmentally friendly and energy-saving material with a new sandwich structure composed of high-strength honeycomb paper core and various high-strength kraft papers. It has the advantages of low cost, less materials, sound absorption and heat insulation, high strength, and good impact resistance. .

　　1. Light weight, less materials and low cost. Compared with various other panel structures, the honeycomb sandwich structure has the largest strength to weight ratio, so the performance/price ratio of its finished products is good, which is the key to the success of honeycomb paperboard. The density of ordinary honeycomb cardboard is about 30~50kg/m, which is 1/3 of the density of common corrugated cardboard. The price of ordinary honeycomb cardboard is only 60% of wood, 50% of steel, and 66% of heavy seven-layer corrugated cardboard. It is lighter and can bring better economic benefits to users.

　　2. High strength, smooth surface and not easy to deform. The honeycomb sandwich structure is approximately isotropic, the structure is stable, and it is not easy to deform. The outstanding compressive resistance and bending resistance are important characteristics required by box packaging materials. The front side of ordinary honeycomb paperboard can withstand 2--5kg pressure per square centimeter , It is 5-10 times the compressive strength of ordinary corrugated cardboard, and the bending strength of ordinary honeycomb cardboard is 2-5 times that of reinforced corrugated cardboard, and 5--30 times that of ordinary corrugated cardboard.

　　3. Good impact resistance and cushioning. Honeycomb paperboard is made of flexible paper core and face paper, which has good toughness and resilience. The unique honeycomb sandwich structure provides excellent cushioning performance and has higher energy absorption per unit volume among all cushioning materials. , The thickness of honeycomb paperboard can replace the EPS plastic foam cushion that has been widely used. According to research, the compressive strength of honeycomb corrugated paperboard increases approximately linearly with the increase of paperboard thickness and length.

　　4. Sound absorption and heat insulation. The interior of the honeycomb sandwich structure is a closed chamber filled with air, so it has good sound insulation and heat preservation performance.

　　5. No pollution, in line with modern environmental protection trends. The honeycomb cardboard is all made of recyclable paper, which can save wood instead of wood and replace EPS plastic cushioning. After use, it can be recycled and reused. The waste and corners of the corrugated box production process can also be die-cut It is bonded to form a honeycomb corrugated cardboard cushion of various shapes. Even if it is discarded, it can be naturally degraded and absorbed. It is a good green packaging material.
