Plastic Pallets are a serious business. If you are going to use them on racking with a load of a tonne or more you really have to go for the best. If you are block stacking then there is much more scope but it is still advisable to choose a pallet with runners that will give greater stability. Otherwise go for the most economical possible usually with nine feet. If your pallets are to be used in a food environment then you have to look at the hygenic features of the pallet.
