Plywood is a material (wood) 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. In the most basic of terms, plywood is made by combining wood veneers together in order to create a flat sheet.

How MDF is manufactured?
Medium-density fibreboard (MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibres, often in a defibrator, combining it with wax and a resin binder, and forming it into panels by applying high temperature and pressure. MDF is generally denser than plywood.
What is the difference between plywood and Plyboard?
Plywood is resistant to moisture and does not carry much risk of water damage. Plyboard, on the other hand, retains moisture and is more likely to suffer water damage. Plywood can sag and bend from the center. Plyboard, on the other hand, is less susceptible to bending because it is more stiff than plywood.
Is MDF stronger than plywood?
