Honeycomb cardboard performance and the difference between corrugated boxes (on)

Honeycomb cardboard is a new type of packaging material that emerges after corrugated cardboard. The manufacture and application of honeycomb paperboard are developed from the invention and application of honeycomb technology. According to relevant information, as early as the 1940s, some developed countries such as the United States and Britain took the lead in researching, developing and applying materials with honeycomb structures in the field of military industry. These materials are characterized by high strength and light weight. Therefore, it can be applied to the manufacture of aircraft wings, which greatly reduces the aircraft's fuselage mass and thus greatly improves the aircraft's speed. Since the beginning of the 1950s, the application of cellular technology has gradually expanded into light construction, decoration, furniture, packaging, storage, transportation and other fields. By the 1960s, with the further development of the papermaking industry and related papermaking industries, there was a paper honeycomb material, what we commonly call a paper honeycomb product.

Paper honeycomb products have a lightweight and reasonable bionic structure and excellent application performance. Its characteristics determine its wide application in the packaging industry. The honeycomb paperboard has a special structure, and has the characteristics of high strength, high load capacity, good elasticity, and light weight. It is especially suitable for the packaging of valuable and fragile products such as electromechanical products and process products. Moreover, the use of paper honeycomb packaging material can greatly save the amount of wood used. This echoes the green packaging advocated and advocated by the packaging industry. In addition, the use of paper honeycomb products on the packaging of export commodities not only satisfies the performance requirements, but also simplifies the quarantine procedures for customs clearance, which greatly facilitates the conduct of foreign trade work.

The structure of the honeycomb paperboard is rather special. It is generally formed by bonding two-layer cardboard and intermediate honeycomb paper cores with adhesives, and has the characteristics of light weight and high strength. Its approximate structure is very similar to that of corrugated cardboard. However, the structure of the paper core in the middle is different. Will be described in detail later with the corrugated board in the manufacture, performance, the use of materials, technology differences. The middle honeycomb core is the most important part of the honeycomb paperboard. It is usually made of special honeycomb paper first cut into certain specifications of the branches, and then through the glue, stretching, molding and other manufacturing processes. From the cross section of the paper core, it resembles a regular hexagonal mesh, which is almost the same as the honeycomb structure. The construction of the paper core largely determines its performance. In general, the thicker the face paper of the honeycomb paperboard, the smaller the honeycomb core hole diameter, the higher the honeycomb core pillar, and the heavier the honeycomb core paper, the better the honeycomb paperboard performance. The special structure of the honeycomb paperboard makes it easy to meet the requirements of the anti-vibration ability of the packaging materials in dynamic transportation.

Both the theoretical research and the production practice, the honeycomb paperboard shows its excellent performance. It not only has excellent performance in terms of strength and elasticity, but also has outstanding performance in compression resistance, shock resistance, moisture resistance and thermal insulation. Moreover, it has recyclable, non-polluting properties. Its excellent performance makes it in a good position to compete with other packaging materials.

The structure of honeycomb paperboard is unique. This unique structure makes it have excellent mechanical properties. First of all, it has been proved that the compressive strength of the facade of paper is 100 times that of other orientations, and 1 g of honeycomb paperboard can withstand 800 g of pressure without deformation. Its compressive strength is absolutely superior to corrugated boxes. Moreover, the cartons made with them can carry larger mass objects. It can even be used instead of wood. Its special structure determines that it is very economical in the amount of raw paper, that is, the cost of raw materials is reduced, and the quality of the cartons is also reduced. Second, its unique honeycomb sandwich structure gives it excellent cushioning properties. It can effectively resist the impact from outside and achieve a good cushioning effect. And, as the thickness of the cardboard increases, its ability to absorb impact energy also increases. In the range of its elasticity, it can also produce a strong anti-vibration capability when subjected to external shocks. Reduce the rate of breakage of the product.

The raw material for making honeycomb paperboard, namely the moisture content in it, and the air content in it decide it has very good sound insulation effect, and a certain heat preservation performance. The main material that makes up the honeycomb paperboard is plant fibers, which makes the honeycomb paperboard easy to process into a variety of shapes and sizes as desired. Moreover, the amount of paper used in the honeycomb paperboard is small, and the honeycomb paper core and the base paper base paper can also be manufactured by using recovered waste paper, straw pulp, and the like as raw materials. Its raw material resources are very rich. Moreover, it consumes very little raw paper and costs little.

As a new type of packaging material, honeycomb paperboard can be completely processed with naturally degradable plant fibers, so it should not produce so-called "white" pollution. Moreover, it can also be recycled and reused, making a typical green packaging material, it just responds to the current environmental protection concept of people protecting the environment and protecting forest resources. Therefore, it has a broader development prospect than foam, plastic and other materials.

Compared with other packaging materials, honeycomb paperboard has many advantages. However, since it is also a product that is processed and molded with plant fibers, it is also inevitably subject to its own defects. First of all, its anti-jamming ability is relatively poor. Secondly, the moisture resistance of honeycomb paperboard and its products without special treatment is very poor. Cardboard function is greatly reduced after rain. In the end, the strength of the cardboard constituting the cardboard is generally not very high. The quality of goods that should be loaded should not be too large. Otherwise it will cause damage to the cabinet.
