1. Pressure test
1. The pressure resistance of the carton refers to the collapse of most of the carton under the pressure of most of the carton, which is instantaneous Dynamic load that damages the carton.
2. Calculation formula for corrugated carton compressive strength:
Commonly used K.Q.Kellicutt formulas, MaltenFort formula, Wolf Formula, Makee formula, Australian APM calculation formula, and so on.
Among them, the Karry Carter formula is often used in the calculation of the compressive strength of type 0201 corrugated carton.
Kailikat formula expression:
The Carey Carter in the United States proposed the formula for calculating the compressive strength of the cardboard box according to the pressure strength and perimeter of the corrugated carton

axz mdash; mdash; corrugated constant

2. Stacking test
1. The strength of the stacking refers to how long the carton is crushed after the weight of the carton, and the strength of the stacking strength is then It refers to the consistency that the carton can withstand under last static, so the former is much greater than the latter.
2. Expression of stacking strength:
pw (h-h)/h times; Code load kg
H mdash; mdash; outer height CM
w mdash; product weight (product box weight) kg
h mdash; mdash; Code height CM
K MDASH; MDash; The fatigue coefficient of corrugated carton is related to the stringing time
