Honeycomb Paperboard Technology and Performance

Honeycomb cardboard structure

Honeycomb paperboard is a sandwich material that uses a biomimetic mechanics structure based on the force principle of a honeycomb hexagonal structure. It is the upper and lower two layers of the panel and the middle honeycomb core paper, with a certain adhesive bonding, shaping, drying formed.

Honeycomb paperboard production process

There are many kinds of honeycomb paperboard production lines used in China. From paper feeding (raw materials) to finished products (honeycomb), it is automatically completed by multiple processes.

The main equipments involved in the honeycomb paperboard production line include: paper supply system, glue supply system, drying system, cutting machine, press pelletizer, conveyor belt, stretching machine, core coating system, core-face composite system, surface pressure Heating plate making machine, cutting board machine, etc., its production process flow chart is:

At the same time on a number of rolls of paper, "longitudinal coating" and pre-indentation composite and drying "slicing" automatically collect "compact" paper core pull "paper core coating" surface paper

Composite "pre-rolling" drying "flattening" cut off "fast separation" collection

(1) Low material consumption, high specific strength and specific rigidity, and light weight.

Bees consume the least amount of material to build the largest and most solid honeycomb. According to scientific research, the geometric structure of the honeycomb forms a structure that resembles an arch bridge as a whole, thereby increasing the compressive strength of the surface by 100 times.

Honeycomb paperboard uses a honeycomb structure and therefore also consumes the least amount of material to obtain maximum volume and maximum strength and stiffness. With the same paper consumption, it is 0.024 g/cm2 higher than corrugated board, and it is close to EPS (expandable polystyrene foam), which is only a few tenth of that of water.

(2) Excellent buffer vibration isolation function.

Honeycomb paperboard has a core structure and has excellent buffer vibration isolation function, close to EPS.

(3) Good heat and sound insulation.

Honeycomb core honeycomb cell is a closed structure, which is full of air and do not circulate. Therefore, it has good heat insulation and sound insulation properties.

(4) Strength and rigidity are easy to adjust.

Change the thickness of the core paper, gram weight or change the honeycomb core aperture, the height of the stem, honeycomb cardboard can get different strength and stiffness.

(5) Special processes can be performed to obtain unique features.

Honeycomb paperboard is a full-paper material, easy to carry out special processing to obtain special properties such as waterproof, fire-retardant, anti-mildew, and curing enhancement. This is one of the reasons why honeycomb paperboard can be promoted and applied.

(6) The export does not need fumigation and is free from quarantine.

Honeycomb paperboard is sterilized and sterilized by infrared drying or microwave drying in the production process. Therefore, there is no need for fumigation and quarantine for export. This can be used to replace the wood to a certain extent for the packaging of export products.

(7) Environment-friendly products.

Honeycomb paperboard has no pollution in the production process, but can be recycled and recycled, and it is also easy to dispose of. Therefore, it can replace EPS as a buffer material.

Although the honeycomb paperboard has the above advantages, it also has some drawbacks, such as poor burst resistance, folding endurance, and puncture resistance, which limits its application in certain aspects; the processing performance is poor and cannot be likened to Corrugated cardboard is very easy to be made into box-type packaging containers. Even if it can be produced, the degree of automation at the time of production is low. At the same time, when printing, poor printability cannot meet the needs of modern decoration and decoration, which also limits its packaging. Aspects of application.
