What is the difference between 200 lb test boxes and 32 ECT boxes?
test refers to bursting strength, while 32 ECT refers to stacking strength. Boxes that meet 200 lb. test boxes are made with heavier paper and have 50% greater bursting strength than 32 ECT boxes. Greater bursting strength means fewer crushed and damaged boxes during shipping.
