Example Embodiment

[0018] The present invention provides a thermal transfer film. In order to make the objectives, technical solutions and effects of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0019] The present invention provides a thermal transfer film, such as figure 1 Shown, including:

[0020] The base layer 10, the release layer 20, the protective layer 30, the transfer layer 40 and the glue layer 50 are connected in sequence; the back of the base layer 10 is provided with a release layer to prevent the transfer film from sticking to the glue layer when it is rolled up Together, it is convenient for the transfer film to be rolled and packaged.

[0021] Specifically, the base layer 10 is a PET film, wherein the thick...

Abstract

The invention provides a heat transfer film and a preparation method thereof. The heat transfer film comprises a base layer, a protective layer, a detachment layer, a transfer layer and a glue layer which are sequentially connected; and an anti-adhesive layer is arranged at the back of the base layer, so that the permeability is good and the printing ink transfer is facilitated. At the same time,the heat transfer film is good in heat transfer effect, fully meets actual requirements of heat transfer printing; and after the transfer of the heat transfer film, a protective film formed on the surface of a product is resistant to alcohol, scratches and friction, high in hardness, and capable of protecting a pattern for a long time; and the heat transfer film is simple in preparation and low inproduction cost.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a thermal transfer film and a preparation method thereof. Background technique [0002] Thermal transfer printing is a type of transfer printing, the essence is to pre-print patterns or characters on the substrate film to form thermal shrinkage. Then, through the action of heat and pressure, the graphics and text of the printing layer are transferred to the process of the substrate. As a relatively mature special printing technology, thermal transfer printing is green and environmentally friendly, and meets international non-toxic standards. Rich layers, small color difference, good reproducibility, can achieve the effect required by the designer. However, the existing thermal transfer film has the problem of permeability, which will affect the winding of the thermal transfer film and the quality of the pattern on the surface. If the pattern after transfer is not protected, th...
