What is the calculation method for the compressive strength of corrugated boxes? The strength standard of corrugated box, GB6543-86 national standard appendix G : corrugated box compressive strength value P should not be less than the value calculated by the following formula: P = K · G ( H - h / h · s ) ( kgf / Cm2 ) The machine that can be used to test the compressive strength of the carton has a carton compression tester specially produced by Bell Test Equipment. It is specially used to test the pressure-proof equipment of packaging containers such as carton and corrugated carton to ensure the quality and safety of the products during storage and transportation.

Where: K- strength insurance factor;
G- corrugated box cargo weight, kgf ;
H- stack height, cm ;
h- high boxes, cm;
S- box bottom area cm2 .
This formula can be simplified in practice: P = K · G ( n - 1 )
Where: n-the number of stacking layers;
K- depending on the length of storage:
< 30 days 1.6 , 30-100 days 1.65 , more than 100 days 2 .
However, some textbooks set it to 3 , which makes the safety factor larger.
If the weight of a convenient noodle box is 3.5kgf and the stacking is 16 layers, the strength of the corrugated box (pressure resistance, the same below) should be:
P=2×3.5 ( 16 - 1 )
　　 =7kgf×15
=105kgf
Some large-scale households have their own strength standards. For example, Nanfeng Chemical Group has a washing powder box strength standard of 350kgf . To make a box for it, the strength must meet this standard.
