Honeycomb knowledge

 

Honeycomb paper is made according to the principle of natural honeycomb structure. It is a new kind of environmental and energy-saving material with sandwich structure, which connects the corrugated base paper into countless hollow three-dimensional regular hexagons by glue bonding method, and forms a whole stress part paper core, and glues the surface paper on both sides.

Characteristic

Light weight, less material and low cost.

Compared with other kinds of sheet structures, honeycomb sandwich structure has the largest strength / mass ratio, so the performance / price ratio of its finished products is better, which is the key to the success of honeycomb paper.

High strength, flat surface, not easy to deform.

Honeycomb sandwich structure is nearly isotropic, stable and not easy to deform. Its outstanding compressive and bending resistance are the most important characteristics of box packaging materials.

Good impact resistance and cushioning.

Honeycomb paper is made of flexible paper core and tissue paper. It has good resilience and resilience. The unique honeycomb sandwich structure provides excellent cushioning performance. It has higher unit volume energy absorption value in all cushioning materials. The honeycomb paper with high thickness can replace the EPS plastic foam cushion which is now widely used.

Sound absorption and heat insulation.

The honeycomb sandwich structure is a closed chamber filled with air, so it has good sound insulation performance.

No pollution, in line with the trend of modern environmental protection.

Honeycomb paper is made of recyclable paper, which can be recycled 100% after use. In the production process of corrugated box, waste products and leftover materials can also be die cut and bonded to make honeycomb corrugated board cushion pads of various shapes. Even if they are not used, they can also be degraded and absorbed by nature. They are good green packaging materials. In European and American countries, wood packaging for imported goods from China must be fumigated, and honeycomb paper as a new environmental protection material [1].

 

application

Honeycomb paperboard has many advantages, such as light weight, large flat compression strength and good cushioning performance. It belongs to environmental friendly green material, but it also has some disadvantages. Therefore, we can make full use of its advantages and make full use of its advantages. Honeycomb paperboard is mainly used in construction industry, packaging and transportation industry, funeral industry, agriculture and other fields.

Funeral and interment application

The low-cost honeycomb paperboard is used to make the "sanitary coffin", which is suitable for one-time use, safe and sanitary, and completely solves the problems of high cost and unsanitary of the "turnover coffin". At the same time, the "sanitary coffin" adhesive is made of starch glue without pollution, which can meet the requirements of non-toxic, tasteless and residue free during combustion. As soon as it came out, it was supported by civil affairs department, funeral unit and hospital. At the same time, it solved the emotional concerns of the family members of the deceased, especially welcomed by the family members of the deceased.

 

Agricultural application

The honeycomb paperboard with single-layer panel and larger honeycomb aperture can be used as agricultural seedling trough. This kind of seedling tank can not only solve the shortage of light, heat and water resources in agricultural production, but also prevent the seedlings from diseases and insect pests in the growth period. Moreover, it can be degraded when transplanting, which will not cause environmental pollution like plastic bags.

Architectural application

Honeycomb paperboard has the advantages of high strength, light weight, heat insulation and sound insulation, which is especially suitable for building, decoration materials and products. It is light in weight and can reduce the load-bearing of the building, so it is particularly suitable for the high-rise building with frame light slab structure which is being popularized. At the same time, because of its good heat insulation and sound insulation effect, it can be made into walls, partitions, doors, etc.

Relevant data show that wall materials account for about 70% of building materials. The State Construction Commission and others have jointly issued a notice, starting from June 1, 2000

We can see the huge market potential of honeycomb paper in packaging construction.

Packaging and transportation

Honeycomb paperboard used in packaging and transportation can not only protect products, but also reduce transportation costs. The specific application is as follows:

(1) Cushion pad, angle brace, etc

Since honeycomb paperboard has good cushioning performance, it can also be used as the cushioning pad and isolation board of packaging like corrugated paperboard, and its honeycomb sandwich structure makes its cushioning performance better than corrugated paperboard.

When it is used as angle pad, generally one layer of paper board and core paper shall be cut according to the size, only the other layer of paper shall not be cut off, and several pads on different sides shall be connected by this layer of paper, and then the corresponding parts to be protected shall be covered in the inner package. Similar to cushion pad, honeycomb paperboard can also be used as corner brace and edge guard of transport package, which is especially suitable for collective packaging. Honeycomb paperboard can also be pressed into a die according to the size of the device to locate the device.

(2) Paper tray

Because of its good plane compression resistance, honeycomb paperboard can be used as the upper and lower planks of pallets, as well as the longitudinal beam or cushion block of pallets. At this time, the standard size of longitudinal beam or cushion block shall be combined and processed by several layers of thick honeycomb paperboard, that is to say, the whole tray is only made of honeycomb paperboard.

(3) Packing box

Like corrugated boxes, honeycomb cardboard can also be processed into cartons. But because the honeycomb cardboard is thick and its strength is greatly affected after bending, it will inevitably affect the strength of the honeycomb cardboard box; at the same time, the processing of the honeycomb cardboard box can not be as convenient and fast as the corrugated cardboard, can not realize automatic production, and the production efficiency is low, so it is limited by a certain amount. Some small mechanical and electrical products can be made of honeycomb paperboard or combined with corrugated paperboard.

 

Advantages and disadvantages

Advantage

(1) Less material consumption, high specific strength and specific stiffness, light weight.

Bees use the least material consumption to build the largest and strongest hive. Through scientific research and demonstration, the geometric structure of honeycomb, forming a whole structure just like the arch bridge, thus improving the compressive strength of the surface by 100 times. Honeycomb paperboard adopts honeycomb structure, so it also uses the least material consumption to obtain the maximum volume, strength and rigidity. In the case of the same paper consumption, higher than corrugated board Close to EPS (expandable polystyrene foam), only a fraction of the water.

(2) Excellent cushioning and vibration isolation function

Honeycomb paperboard is of core structure, with excellent cushioning and vibration isolation function, close to EPS.

(3) Good heat and sound insulation performance

The honeycomb hole of the honeycomb core is a closed structure, which is filled with air and does not circulate with each other. Therefore, it has good heat and sound insulation performance.

(4) Easy to adjust strength and rigidity

By changing the thickness and weight of the core paper or the hole diameter and the height of the core, different strength and rigidity can be obtained.

(5) Special process treatment can be carried out to obtain unique functions

Honeycomb paperboard is a kind of all paper material, which is easy to be treated by special process to obtain special properties such as waterproof, flame retardant, mildew proof, curing and reinforcement. This is also one of the reasons why honeycomb paperboard can be widely used.

(6) No fumigation or quarantine for export

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

(7) Environmental protection products

Honeycomb paperboard is pollution-free in the production process, can be recycled, and easy to be discarded. Therefore, EPS can be replaced as buffer material.

shortcoming

(1) It has poor breaking resistance, folding resistance and puncture resistance, which limits its application in some aspects;

(2) The processing performance is poor, so it can't be easily made into box type and other packaging containers like corrugated board. Even if it can be made, the automation degree of production is low;

(3) At the same time, printing adaptability is poor, which can not meet the needs of modern decoration, which also limits its application in packaging.
