When you want to make the cardboard gift box for your product packaging, you need to know the thickness of the greyboard that you want. The greyboard is also called chipboard paper. They are the paper core of the cardboard box. Our common cardboard boxes are using the thickness from 1.2mm to 2mm(750gsm to 1300gsm). You can also use the following formula to converse grammage to thickness. 


Thickness(mm) = Grammage(gsm)*1.55 / 1000


It is the estimated thickness and the accurate thickness will have ±0.1mm deviation.



Moisture Content of the Greyboard affects the Stiffiness


The moisture content affects the greyboard stiffiness. The moisture degree varies from 8% to 13%. When the moisture content is low, the cardboard gift box will have the very good stiffiness, resistant to the bending. Also, the price of the low moisture content greyboard will be higher than the normal greyboard. For the grade A greyboard, the unit ton price would be around USD$800-1000 while the ordinary greyboard would be around USD$500-700.
