(1) light weight, less materials and low cost. Honeycomb sandwich structure has the biggest strength / mass ratio compared with other kinds of plate structure, so the performance / price ratio of its finished product is good, which is the key to success of honeycomb paperboard.

(2) high strength, smooth surface, not easy to deformation. Honeycomb sandwich structure is approximately isotropic and has good structural stability, and it is not easy to deform. Its outstanding compressive strength and bending resistance are the most important characteristics of box packing materials.

(3) good impact resistance and good cushioning property. The honeycomb cardboard made of flexible paper core and made of paper, has good toughness and elasticity, honeycomb sandwich structure provides a unique buffer with excellent performance, with all the materials in the buffer unit volume of higher energy absorption value, high thickness of honeycomb paperboard can be EPS foam cushioning plastic pad has the extensive use of the alternative.

(4) sound absorption and heat insulation. Honeycomb sandwich structure is a closed chamber, which is filled with air, so it has good sound insulation and heat preservation performance.
