This study was carried out to analyze the effects of packaging units and loading types in agricultural products(apple, pear, and sweet persimmon) palletization. In apple and pear packaging, an optimum loading type was pin wheel loading, and load effective corrugated box dimension was $330{ imes}220{ imes}170mmm(L{ imes}W{ imes}H)$ in 5 and 10kg packaging units, but in case of pear box was 10mm higher than apple box. However, in sweet persimmon packaging, block loading was available, and box dimension of $365{ imes}275{ imes}180mm(L{ imes}W{ imes}H)$ was the most effective to palletize.
