The difference between three layer corrugated box and five layer corrugated box

The main differences are as follows:


1、 Difference between single and double layers


（1）. Single corrugated board, also known as three-layer board: single wall;


（2）. Double corrugated cardboard is also known as five-layer cardboard: double wall.


2、 Difference between stacking strength and compressive strength


The stacking strength and compressive strength of five-layer corrugated boxes are greater than those of three-layer corrugated boxes


The required compressive strength of the carton=[Gross weight of the carton * (stacking layers - 1)] * Safety coefficient K. The front section is the static stacking strength of the carton.


The K value depends on the number of printing plates, the degree of opening, the nature of the inner packaging, the degree of value, storage and transportation time, conditions, etc. The K value is generally taken as 2/3/4/5.


3、 Different production processes
