The main technical characteristics of honeycomb paperboard

1. Very light weight, less materials, low cost

Compared with other various panel structures, the honeycomb sandwich structure has the largest strength / weight ratio, so the performance / price ratio of its finished products is good, which is the key to the success of honeycomb paperboard. For example, the density of ordinary honeycomb paperboard is about 30-50kg / m3, which is about one third of the density of ordinary five-layer corrugated paperboard, and the material cost of ordinary honeycomb paperboard is about three-thirds of that of heavy-duty seven-layer corrugated paperboard equivalent to its strength. of two. Compared with EPS foam, under the same compressive strength, honeycomb paperboard is 20% -30% lighter than EPS, saves materials, and the price is lower than EPS material.

2. High strength, flat surface, not easy to deform

The honeycomb sandwich structure is approximately isotropic, has good structural stability, and is not easily deformed. Its outstanding compression resistance and bending resistance are the most important characteristics required for box packaging materials. Ordinary honeycomb paperboard can withstand 2-5 kg ​​of pressure per square centimeter, which is 5-10 times that of ordinary corrugated paperboard. The bending strength of ordinary honeycomb paperboard is 2-5 times that of reinforced corrugated paperboard, and 5-30 times that of ordinary corrugated paperboard. Compared with EPS foam, under the same density, the compressive strength of honeycomb paperboard is 30% -50% higher than that of EPS foam.

3. Good impact resistance and good cushioning

The honeycomb paperboard is made of flexible paper core and facial paper, which has good toughness and resilience. By changing the paper weight or pore size of the honeycomb paper core, and changing the gram weight of the facial paper, it is convenient to change the resistance of the honeycomb paperboard Compressive strength and cushioning performance. At present, the high-thickness honeycomb paperboard can replace the EPS plastic foam cushions that have been widely used or used as cushioning plates between shipping packages through simple processing.

4. Sound absorption and heat insulation

The inside of the honeycomb sandwich structure is a closed cell, which is filled with air, so it has good sound insulation, heat insulation and thermal insulation performance.

5. No pollution, in line with modern environmental protection trends

The honeycomb paperboard is all made of recyclable paper, which can be recycled and reused 100% after use. Even if it is discarded, it can be degraded and absorbed by nature. It is a very good green packaging material.
