How much do you know about the structure of corrugated cardboard production lines? Let's follow the editor of the three-layer corrugated cardboard production line to learn and take a look!

The single sided corrugated cardboard production line consists of one layer of cardboard and one layer of corrugated base paper. This type of cardboard has no mesh, so it cannot be used to make cardboard boxes. It is usually used to protect fragile items and serve as a buffer.

Double sided single corrugated cardboard is made by bonding two layers of cardboard and one layer of corrugated base paper. This type of cardboard is mainly used for the production of small and medium-sized outer packaging boxes. It accounts for a high proportion in corrugated cardboard. Generally speaking, by changing the type and quantity of cardboard or corrugated base paper, corrugated cardboard with different strength characteristics can be obtained to meet various transportation and packaging needs.

Double sided and double-sided are made by bonding three layers of cardboard (surface, inner, and core) and two layers of corrugated base paper. This type of cardboard has a large quantity and high strength, and the cardboard boxes made from it have great stiffness and can withstand high external pressure and the outward expansion force of the packaged goods inside the cardboard boxes. This type of cardboard box is mainly used for packaging various heavy and colored goods.

Double sided three-layer cardboard is made by bonding four layers of cardboard and three layers of corrugated base paper. This type of cardboard has a larger unit weight and higher strength. Due to its large thickness and strong rigidity, it can pack increasingly heavy goods, and sometimes it can be used to make special liners with its high strength.

Corrugated cardboard, as a composite material, is mainly due to its excellent mechanical properties. These mechanical properties are not only related to the manufacturing process level and component quality of corrugated cardboard, but also to the shape and type of grooves in the corrugated paper core. The shape of corrugated cardboard directly affects its compressive strength, and the groove pattern of corrugated cardboard and its reasonable selection and combination can fully utilize its own characteristics.
