Light weight, less material, low cost.  Honeycomb sandwich structure has the largest strength/mass ratio compared with other plate structures, so its finished product performance/price is better, which is the key to the success of honeycomb cardboard.  Sound absorption and heat insulation.  The honeycomb sandwich structure is a closed chamber, which is filled with air, so it has good sound insulation and insulation performance.   High strength, smooth surface, not easy to deformation.  Honeycomb sandwich structure is approximately isotropic, good structural stability, not easy to deformation, its outstanding compressive and bending ability is the most important characteristics of box packaging materials.   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 a higher energy absorption value per unit volume in all the cushioning materials. Honeycomb paperboard with high thickness can replace…
