Network structure of corrugated cardboard

The network structure of corrugated cardboard, the inner layer is made of corrugated paper, the adjacent corrugated paper, the length direction of the corrugated paper are perpendicular to each other or at an angle, at the intersection of the enthalpy and enthalpy are bonded to each other in a lattice network. Depending on the need to determine the number of layers, the surface coated cardboard, you can get the network structure of corrugated cardboard and its products. Such as various types of cabinets, septa and other cardboard products. See the schematic diagram of the network structure of corrugated cardboard.

The network structure of corrugated cardboard is due to the fact that corrugated paper is placed perpendicularly or at an angle to each other and bonded by a network of lattices. Therefore, the equilibrium capacity of the corrugated cardboard is improved in all directions. The corrugated paper replaces the original core paper layer. Reduced weight.

The network structure of corrugated cardboard is to change the structure of the original corrugated cardboard, fully utilize the characteristics of the corrugated paper to withstand the long direction, and increase the thickness of the cardboard, improve the anti-jamming, anti-pressure, anti-loop pressure and side pressure in all directions. Ability and impact resistance, and increased flexibility. The products made from this paperboard, such as 9 carton boxes, etc., have been balanced to improve the overall capacity of corrugated paperboard and products, and they ensure the use of performance. With five layers of paperboard, 296g of paper can be saved per square meter, reducing the quality by about 13%. This not only saves raw materials and reduces costs, but also reduces shipping costs, and reduces the labor intensity of the porters. At the same time, domestic cardboard can be used instead of imported cardboard to save part of foreign exchange and reduce the cost. Heavy-duty corrugated cardboard that can replace wooden packaging

The heavy-duty corrugated cardboard produced by the world's top-class production line, and the well-developed production process, its strength has far exceeded the scope of the general corrugated cardboard packaging. A length of about one meter, one-half meter high 1300G empty carton withstand a Nearly 2 tons of vehicles under the test of heavy pressure and hot and humid weather, can not collapse the whole day, its strength can be imagined.

1300G seven-layer and 8520G five-layer heavy-duty corrugated cardboard, in line with US Federal Standard PPP-B-640d, railway standard Rule41, truck standard Rule222 and government-related standards in 42 countries around the world. Use this product and use other packaging materials, especially Compared with wood packaging, it has the following advantages: reduce packaging costs, easy to recycle, protect the environment; light weight, can save freight; can carry out high storage; can be sealed packaging; suitable for many national standards; strong moisture resistance; with recycling signs No fumigation treatment required; can be printed on the surface of the box; can be made into extra-large size packaging; can be stacked in the packaging and transport process, can accept a small amount of orders.

Many wood packaging and heavy duty corrugated paperboards reduce the overall logistics cost by as much as 10% to 40%, and enhance the protective performance of the product, thus providing a strong guarantee for the realization of the customer's product value.
