In 1797 Samuel Bentham applied for patents covering several machines to produce veneers. In his patent applications, he described the concept of laminating several layers of veneer with glue to form a thicker piece – the first description of what we now call plywood. Samuel Bentham was a British naval engineer with many shipbuilding inventions to his credit. Veneers at the time of Bentham were flat sawn, rift sawn or quarter sawn; i.e. cut along or across the log manually in different angles to the grain and thus limited in width and length.
About fifty years later Immanuel Nobel, father of Alfred Nobel, realized that several thinner layers of wood bonded together would be stronger than one single thick layer of wood ; understanding the industrial potential of laminated wood he invented the rotary lathe.
The typical structure of plywood (plywood) is the thin surface layer, the thick core layer. Why do people not do the layer with the same thickness? Because when the core layer thicker than surface layer, it will strengthen the links of the surface layer, where stand out the most impact. The result is that when there are external forces, the outer layer will absorb most of it, and the impact force into the core layer is almost zero. Especially when we cut the plywood, this structure makes the surface layer less be torn, and then ensuring the aesthetics of sheet material.
Currently the pallet is used common in factories, warehouses, supermarkets, … for packing of goods. Due to the high leg and firm, the pallet helps the goods is not in direct with the floor, or easily to transport by forklift.
There are many types of pallets such as steel pallets, plastic pallets, wood pallets, each pallet types have their own advantages and disadvantages. With wood pallet, its key advantages is simple in production process, easily to make different pallet sizes, different load capacity without depending on the specifications available as plastic pallets. Easy to repair pallets for re-usability. With wood pallet not repaired, the components can take advantage of it as art crafts, paintings, framed prints, which can be crushed to squeeze into plywood products … or maybe as fuel. Therefore, now about 90% of the world’s pallet is wood pallet.
