What is Plywood?
Plywood is a type of engineered wood product that is made by bonding together several thin layers of wood veneers, known as plies or layers, with the grain of each layer oriented perpendicular to the adjacent layer. This cross-grain construction gives plywood its strength, stability, and dimensional integrity. 
The individual layers of wood veneers used in plywood are usually sourced from various species of hardwood or softwood. The veneers are typically peeled or sliced from logs and then layered and glued together under high pressure and heat. The adhesive used in plywood manufacturing is typically a type of resin, such as urea-formaldehyde or phenol-formaldehyde, which creates a strong bond between the wood layers.
