Performance test of corrugated board and honeycomb board

The corrugated box and honeycomb box with the same face paper and core paper, the same amount of paper and the same adhesive between the core layer and face paper are tested for performance. The test data are shown in Table 1.

Standardization specified by data:

(1) The flat pressing strength of honeycomb cardboard is much higher than that of corrugated paperboard, and when the amount of consumables is certain, the flat pressing strength of honeycomb paperboard decreases with the increase of pore size.

(2) The lateral compressive strength of honeycomb paperboard decreases with the increase of pore size; The lateral compressive strength of corrugated board is much higher than that of honeycomb board, while the lateral compressive strength is lower than that of honeycomb board.

(3) The bending strength of honeycomb paperboard is higher than that of corrugated paperboard, and its bending strength increases with the increase of aperture.

(4) The peel strength of corrugated board is higher than that of honeycomb board; The peel strength of honeycomb paperboard increases with the decrease of pore size.

(5) There is basically no big difference in the puncture strength between honeycomb paperboard and corrugated paperboard.

From the above analysis, it can be seen that the development of corrugated board and honeycomb board has reached the limit and the other is difficult, so we must develop a new world. If corrugated board and honeycomb board are combined, the advantages of corrugated board and honeycomb board can be brought into play, and the side compression strength and flat compression strength of its composite board can be improved. In addition, when making the packing box, if the corrugated box is used as the box and the upper and lower walls of the box are padded with honeycomb paperboard, the shockproof, compression resistance, thermal insulation, puncture resistance and bearing capacity of the packing box can be improved. Therefore, at this stage, corrugated board and honeycomb board can not become competitors to each other, but should become partners in production and application.

Corrugated board and honeycomb board have their own advantages. To sum up, the advantages of corrugated board are: strong strength, mature products and strong talents, but the enterprise has excess production and urgently needs to develop new markets. The advantages of honeycomb paperboard are: large market, new products and good benefits, but the enterprise scale is small, the development is not fast and there are many difficulties. I hope to get strong support from the corrugated paperboard industry. Therefore, the two should be combined, complementary advantages and common development, which is the inevitable trend of scientific development.
