ASTM D4169 - Standard Practice for Performance Testing of Shipping Containers and Systems.
Stacking strength refers to the warehouse storage of corrugated boxes packed under static pressure, just before collapse can withstand the load. Stacking strength can be tested by stacking strength test, but also calculated according to the test compressive strength. Stack strength refers to the load refers to the lowest layer of cardboard load, that is, the lowest layer of stacking strength. Stacking strength and compressive strength, as an important basis for measuring the strength of corrugated boxes, in modern transport and packaging design, stacking strength is more meaningful and practical value.
