The manufacturing size of the carton is the blanking size when making the carton. The manufacturing dimension is measured by the pressing line on the unfolded box blank. The indentation roller on the slitter presses out a groove at the line pressing position, and the line pressing is the center line of the groove. The distance between the two pressing lines is the manufacturing dimension. The conversion of manufacturing dimensions into inner and outer diameter dimensions can be quickly completed through table 2, but they also have their own measurement methods.

Corrugated box can be divided into single splicing and double splicing in the manufacturing process

Single splicing refers to one page forming box, which is generally used for cartons with small perimeter; Double splicing is also called two page carton. Some cartons have too large circumference and have to use two pieces of box blank to piece up a carton. However, sometimes in order to make use of the surplus materials cut down in the production process, the carton factory will also use two pieces to piece up a carton that is not too large, or even four pieces. Compared with one page box, two page box has one more joint, so there are some slight differences in the area calculation between the two.
