Corrugated Plastic Sign Manufacturer introduces the main production process of corrugated boxes:

1.The size of the corrugated box:

①Inner size: depends on the maximum outer size of the inner packaging, the quantity of inner packaging, the packing arrangement, and the type of inner packaging.

②External dimensions: measure the vertical distance between the carton and the outer sides of the two boxes;

③ Manufacturing size: the unfolded size of the carton before it is formed, and the bottom paper surface after unfolding is measured.

④The relationship between dimensions: a. Outer size = inner size + 2 * cardboard thickness (in fact, the thickness loss of the manufacturing process should be considered) b. Manufacturing size = outer size-coefficient (this coefficient generally depends on the number of layers of cardboard and Material). C. In fact, it is necessary to take the upper and lower deviations according to the characteristics of different customers; D. Generally, there are two ways to design the carton size: design the inner diameter of the carton according to the maximum outer diameter and arrangement of the inner packaging; according to the internal space size of the standard container Design the outer diameter of the carton.
