A Review of Postprinting and Preprinting of Corrugated Cardboard
The single-layer corrugated cardboard consists of a paper sheet on both sides of the original corrugated medium. Such a structure results in greater strength than the three-layered paper used, while also maintaining a relatively light mass at this thickness. Ordinary corrugated board types include G, F, E, B, C, and A, in which the G-type corrugated file has the lowest cassette height and the A-type corrugated file has the largest cassette file. Different twist heights combined with different...
Analyze the side pressure strength and correlation of corrugated cardboard
The side pressure strength, also called the vertical compressive strength, is to apply pressure to the corrugated cardboard samples in the vertical direction. The maximum force the cardboard can withstand during the pressure application is the side pressure strength of the carton. The compressive strength of the carton mainly depends on the paperboard side pressure strength, while the side pressure strength is related to the transverse crushing strength of the layers of the base paper which...
Haida teaches you corrugated cardboard ink flexo common troubleshooting
In packaging printing, flexographic printing corrugated board is becoming more and more widespread. Water-based ink is one of the commonly used environmentally-friendly inks, and the printability of corrugated paperboard is also relatively good. Therefore, the application in corrugated board printing has also increased significantly. But the corrugated board surface is poor in smoothness and requires a higher printing pressure. The flexographic printing is called kiss printing. The control of...

Corrugated cardboard carton several special printing system explanation
In the case of a single-faced corrugated board production line, if the glossy paper is still to be coated after finishing the printing of the facing paper, and the production volume is large, it may not be printed on the surface paper, but a gravure printing method is used to complete the gravure printing on the plastic film. Add a white primer, then the printed plastic film and the paper first compound, and then complete the box according to the conventional carton forming process. Process...
Corrugated cardboard, carton box shape and waveform
Corrugated corrugated corrugated corrugated cardboard has a different function of bonded corrugated board. Even if the same quality of facial paper and paper is used, the performance of the corrugated paperboard formed has a certain difference due to the difference in shape. The common corrugated shapes in the world are divided into four types: Type A, Type C, Type B, and Type E. Their technical indicators and requirements are analyzed below: The corrugated cardboard made of A type ramie has...
Corrugated cardboard edge pressure strength and burst strength calculation
Bursting Strength Test BST (Bursting Strength Test) Break strength is the static rupture strength in kpa. Bursting strength can be measured by a burst strength tester. The burst strength of raw materials such as corrugated medium and cardboard is in accordance with the relevant standards. The burst strength of corrugated board can be inferred from the raw materials used. It is equal to the sum of the burst strength of each layer of board paperboard multiplied by a factor of 0.95. Layer...
