Wood Grain Laminated Plywood

Laminated plywood is a 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 then coated with soft or hard thin sheet of PVC with smooth or 3D touchable wood grains sense in one or both sides. These types of plywood use in large varieties of decorative in sides of our life. All plywood’s bind resin and wood fiber sheets (cellulose cells are long, strong and thin) to form a composite material.

This alternation of the grain is called cross-graining and has several important benefits: it reduces the tendency of wood to split when nailed at the edges; it reduces expansion and shrinkage, providing improved dimensional stability; and it makes the strength of the panel consistent across all directions. There is usually an odd number of plies, so that the sheet is balanced, this reduces warping. Because plywood is bonded with grains running against one another and with an odd number of composite parts, it has high stiffness perpendicular to the grain direction of the surface ply.
