Plywood, commonly known as plywood, is a three-layer or multi-layer (usually odd numbered, 3-13 layers) board like material made from natural logs that are boiled and softened, and spun along the annual ring into large thin sheets (veneers) with a thickness of 2.7mm-20mm or more. According to the principle of symmetry, it is generally composed of three or more layers of thin veneers with a thickness of one millimeter, which are vertically assembled according to the direction of adjacent wood grain fibers, and dried, assembled, glued, hot pressed, and glued.

The high-quality product has a flat and smooth board surface, without debonding, sand damage, pressure damage, obvious color difference, and stains. The size processing accuracy is good, the thickness deviation is small, the bonding strength is 0.7Mpa, and the moisture content is 6-14%. Usually used as a substrate and also as a panel, it can be used in construction, interior decoration, furniture manufacturing, shipbuilding, packaging, and other industrial product manufacturing
