Plywood is a sheet material manufactured from thin layers or "plies" of wood veneer that are glued together with adjacent
layers having their wood grain rotated up to 90 degrees to one another. It is an engineered wood from the family of manufactured
boards which includes medium-density fiberboard (MDF) and particle board (chipboard).
All plywood's bind resin and wood fibre sheets (cellulose cells are long, strong and thin) to form a composite material. Lamination is the technique
of manufacturing a material in multiple layers so that the composite material achieves improved strength, stability, sound insulation, appearance or
other properties from the use of differing materials.
