[0002] The transfer film is composed of a decorative layer printed on a PET polyester film as a backing paper, and a protective layer, a base color layer, a release layer and a hot melt adhesive layer coated on the surface. It is mostly used on the surface of the decorated building materials to form a high-quality finishing film, which is not only beautiful, but also can effectively protect the surface of the building materials. During the production and processing of the transfer film, the transfer film needs to be dried. Therefore, a drying device for the production and processing of the transfer film is required to work.
