If you've ever ordered a large amount of product or even bought an item from the store, then you have come in contact with an item that was shipped using pallets. Pallets are normally square wooden structures that are used to carry supplies/products on top of them.
The items are stacked on top of the pallet and are normally wrapped heavily in plastic to keep the stack from toppling. Pallets are used for shipping because without them you'd have two almost impossible options.
You can check this out if you want to buy pallets.
You'd either have to ship all your items separately, which would take forever to load and unload or you could wrap all your items, but it would be impossible to load or unload because it would be too heavy to lift by hand, but products would be easily damaged using a forklift.
Using pallets is really the only way to go. There are a few different types of pallets including wooden and plastic. Each has its advantages and disadvantages for you to take into consideration.
Traditional is Traditional for a Reason
The traditional structure for pallets is wood. Wooden pallets may not be pretty, but they're practical. Wooden pallets are easy to manufacture and are therefore cheaper to purchase.
Wood is an easy material to come by and is easy to assemble into a pallet. Therefore you aren't paying for the cost of manufacturing the pallet as you would be with a higher quality pallet. Wood is very sturdy and you won't have to worry about your products being damaged by a collapsing pallet. If you're looking for a cheap, sturdy option, wood is the way to go.
