Heat transfer film is made of polyethylene film lined with paper printed with wood grain decorative layer. The surface is coated with a protective layer, a base color layer, a defilm layer and a hot melt adhesive layer. By heating the high temperature silicon roller, the temperature and pressure are applied to the transfer foil, so that the transfer layer composed of the decorative wood grain printing layer, surface protection layer and the base color layer is separated from the polyethylene, and the transfer layer is transferred to the surface of the wood-based panel or furniture parts, and the decorative surface pattern is formed, and the surface has excellent properties such as wear-resistant, heat resistant and light resistant, the pattern is novel and beautiful, and the color is stable. It is a widely used decorative material.
