Method for manufacturing formaldehydeless plywood and formaldehydeless multi-layer wood substrates

The invention relates to a formaldehyde free laminated wood board and multi layer real wood material manufacture. It is made by putting the veneer horizontally crossing, laying fuse glue film or thermal plastic film between veneers to form board sets, then hot forming, pressurizing, cooling to normal temperature to get the final product. Using fuse film or thermal plastic film, it replaces the formaldehyde free adhesive agent to prevent the stretch of the veneer due to the absorption of water to increase the stability of the laminated board size.
