The use of pallet seems to be very practical, where goods placed on it will be orderly arranged and fixed in amount so that this makes a positive impact for trade activities particularly in shipping goods and loading or unloading them. The goods are still in the ordered stacking and with a countable amount or in other words, they could be counted exactly if there is a difference amount of goods in a pallet . Conventionally, a pallet is generally made from wood or plastic materials, which are apparently cheap in cost for making them. However, due to environment aspects recently, wood constitutes protected raw materials, which are limited for the purpose of environmental preservation.

Goods placed on a pallet commonly has a fixed quantity and packed using plastic ropes or wires or other materials in order to make them strongly tied to the pallet. However, there is a problem in the practice to arrange pallets both in storage cabins and in containers for later shipping of the goods. When pallets are arranged in row lines, there will be a necessity for a very big space or yard. Whereas, if pallets are arranged in a stacking, another problem will exist where the goods placed in the bottom part of stacking will be broken, particularly if the goods are fragile or at least, the packaging or supporting for the goods in the bottom part will be broken.
