Happy to see you here.
Hope you are well !
Today, we are going to know, How to calculate the compression strength of corrugated fibre box theoretically.
First of all, what is compression strength of corrugated fibre box?
It may be defined as the ability of box to withstand the amount of compressive force applied on it before going under deformation.
By the help of McKee formulae we can calculate the box compression.
BCT= 6 X ECT X √Z X √T
Where,
BCT = Box compression test in KgF.
ECT = Edge compression test in KgF/cm.
Z = Perimeter of box.
T = Thickness of board.
*ECT = 1.28 ( RCTL1+mRCTL2+RCTL2)
The above formulae is for 3 ply. So you have to change RCT and m according to the no of ply.
where, m = Take up factor of flute.
