[0002] Plywood is a three-layer or multi-layer board material made by peeling wood segments into veneers or planing wood blocks into veneers, and then gluing them together with adhesive. It is usually made with an odd number of veneers, with the fibers of adjacent layers of veneers glued perpendicular to each other.

[0003] Plywood is one of the commonly used materials for furniture and one of the three major artificial boards. It can also be used as material for airplanes, ships, trains, cars, buildings and packaging boxes. The existing plywood on the market still has the disadvantage of single function. During use, traditional plywood is generally made of multiple layers of board glued together, and there is no sound insulation material inside, resulting in poor sound insulation effect, single function and inconvenience in use. When used for decoration, positioning and fixing methods such as screws and pins are not very suitable because they require holes to be left on the surface of the plywood. Gluing two boards together can easily lead to problems such as uneven joints and insufficient strength of the joint. Utility Model Content
