Heat transfer film is a kind of medium material for thermal transfer process. The process of heat transfer printing is a process of transferring the decorative pattern on the surface of the decorative building material to form a high-quality decorative film by the heat transfer film. In the process of heat transfer, the protective layer and the pattern layer are separated from the polyester substrate by the joint action of heat and pressure. Heat transfer film is made of polyethylene film as a wood grain decorative layer lining paper. The surface is coated with a protective layer, color layer, a release layer and hot melt adhesive layer. By heating high temperature silicon roller, the temperature and pressure applied to a transfer foil on the printed surface decorative wood layer, protective layer, color layer and transfer layer of polyethylene detachment, transfer to the surface of artificial board or furniture parts above, they formed a decorative pattern on the surface, and the surface has excellent performance, wear resistance and heat resistance light, novel and beautiful patterns, color stability, is a widely used decorative material.
