Packages should be stacked on flat, even surfaces, preferably above floor level
•Uneven stacking reduces pack strength: an inch of misalignment lowers box top-load resistance by 30%
•Stacking on pallets should be compact and neat, preferably secured with straps or wrapping
•“Crosstie” stacking of corrugated board boxes (at below) can reduce top-load resistance by up to 50% -so use only for the top layer
