Sale Bulk Honeycomb Corrugated Cardboard Sheets Pallets and Panels Producers

Honeycomb cardboard is popular in the market for its lightweight, low price, high strength, recyclability, and other characteristics, especially in developed countries and regions such as the Netherlands, the United States, Japan, etc. It has become a new type of green packaging with the ability to save resources and protect the environment. Honeycomb cardboard packaging box is the ideal packaging for China's export commodities. Its popularisation and application can, on the one hand, reduce the breakage rate of commodities in the circulation process; on the other hand, it can replace wooden boxes and reduce the cost.

Introduction of honeycomb cardboard

Honeycomb paperboard is manufactured according to the mechanism of honeycomb structure in nature, which is a more successful case of bionics application. It is a new type of environmentally friendly and energy-saving material of the sandwich structure, which is made of corrugated raw paper connected into countless hollow three-dimensional hexagonal shapes by adhesive bonding to form an integral stress member - paper core, and bonded with face paper on both sides.

c - Honeycomb side length. The length of the hexagonal side of the honeycomb core, mm;

d - Honeycomb inner diameter. The diameter of the inner circle of the hexagonal shape of the honeycomb core, mm;

d=√3 c

t - Height of honeycomb core, mm;

a - Honeycomb aperture distance. The distance between the centers of two adjacent honeycombs in the tensile direction, mm;

i - Aperture ratio. The ratio of honeycomb aperture distance to its inner diameter, i=a/d. Properly stretched, then i=1; overstretched, then I>1; understretched, then I <1.

Manufacturing process

The first part of the honeycomb paperboard production line is the unit for manufacturing honeycomb hexagonal structured paper core, which is a pre-process, and the quality, specification, and shape of the core paper are the basis of honeycomb products.

The second part is the unit for composite paperboard on and off the paper core, which is the latter process. The quality and level of post-processing are important links to ensure the quality of honeycomb products. Honeycomb cardboard production process is ① core: winding, laminated, paper strip butt type, continuous paper strip type; ② gluing: spray glue method, gluing method, full-width gluing method; ③ stretching: limited-width stretching, differential stretching, a differential and limited-width combination of type, transverse stretching; ④ composite: gluing composite on the surface, flute gluing composite; ⑤ compaction: compaction, extrusion compaction, roller compaction pressure machine; ⑥ cut strip: There are paper cutter cutting, round knife slitting, single; in the knife cutting; ⑦ splicing: manual splicing, semi-automatic splicing, automatic splicing (core strip docking, paper strip splicing, and gluing); ⑧ heating and drying: electric heating, steam heating, heat-conducting oil heating; ⑨ longitudinal and transversal cuts: computer-controlled, work program control; ⑩ special treatment: hair treatment, exhaust treatment, increase the contact surface treatment.

Honeycomb cardboard characteristics

Lightweight, less material, and lower cost.

Honeycomb sandwich structure has the largest strength/mass ratio compared with various other panel structures, thus its manufactured products have a good performance/price ratio, which is the key to the success of honeycomb paperboard.

High strength, flat surface, not easy to deform. The honeycomb sandwich structure is nearly isotropic, with good structural stability, and not easy to deform, and it's outstanding compression resistance and bending resistance are the most important characteristics needed for box packaging materials. Good impact resistance and cushioning. Honeycomb paperboard is made of flexible paper core and face paper, with good toughness and resilience, the unique honeycomb sandwich structure provides excellent cushioning performance, the cushioning material has a higher value of energy absorption per unit volume, the high thickness of the honeycomb paperboard can be a substitute for the large number of EPS plastic foam cushioning used now. Acoustic and thermal insulation.Honeycomb sandwich structure inside the closed chamber, which is full of air, so it has good sound insulation and heat preservation performance.No pollution, in line with the modern trend of environmental protection. Honeycomb cardboard is made entirely from recyclable paper materials and can be 100 percent recycled after use. Relationship with Corrugated BoardHoneycomb cardboard and corrugated cardboard are two kinds of recyclable and environmentally friendly materials, and they are also two kinds of packaging materials widely used in China's packaging industry. Since honeycomb paperboard has many advantages such as high strength, good rigidity, buffering, heat preservation, heat insulation, sound insulation, etc., and has good development and application prospects, the theoretical and experimental research on honeycomb paperboard is a research hotspot for various packaging research institutes and packaging enterprises. As we all know, for small loads, the corrugated board has good shock-absorbing performance, and the honeycomb board has good pressure-bearing capacity.
● Grooving of corrugated board

● Honeycomb board groovingThickened honeycomb paperboard with thick cardboard as the top layer can be made into vigorous pallets, which are light in weight and good in strength, and can replace the pallets made of wood that are used in large quantities in the export packaging industry and the domestic transport industry, reducing deforestation and protecting the ecological environment. Honeycomb cardboard in heavy-duty packaging shows great superiority and can make multi-layer corrugated cardboard difficult to handle the thick wallpaper, box edges with kraft paper corner protectors, or high-strength corrugated cardboard heaven and earth cover surrounded to replace or partially replace a large number of wooden boxes now used in the packaging, paper instead of wood, reduce costs, save forest resources. Detachable honeycomb box: heat and pressure resistant, easy to dismantle without taking up space, inexpensive, strong resistance to adversity, resistance to dryness, water, and humidity (can be coated with PET film), insect-proof, moth-proof and anti-corrosion. Honeycomb cardboard can be made into different shapes without molds but only with simple tools such as slitting, creasing, etc., to make a liner adapted to the shape of the product. Replacement of polystyrene (EPS) foam liner in the box, not only solves the serious problem of white pollution of plastic foam, but also reduces the volume of the packaging container, reduces packaging materials, and reduces transport costs.

In short, honeycomb paperboard in the electromechanical industry can be used to pack heavy-duty electromechanical products, such as engines, automobile cylinders, motorbikes, high-voltage electrical appliances, heavy machinery parts, etc.; in the electronic and electrical appliances and instrumentation industry, can be used for packaging, such as computers, air conditioners, refrigerators, picture tubes, televisions, a variety of electrical appliances, as well as high-precision instrumentation, etc.; in the building materials industry, the honeycomb paperboard is packaged in flat glass and sanitary ceramics, In the building materials industry, honeycomb paperboard is a good material for packaging flat glass and sanitary ceramics, sanitary ware, which can greatly reduce the breakage rate of glass, ceramics and other fragile items in the transport process.
