Description

Technical Field

[0001] This utility model belongs to the field of transfer film technology, specifically relating to a white ink heat transfer film that can impart a metallic sheen to printed materials. Background Technology

[0002] In the process of white ink heat transfer printing, the main existing method to achieve a metallic sheen on the printed image is through a lamination process using hot stamping film. However, because hot stamping has a certain degree of opacity, it covers the original image after lamination, preventing the printed image from fully displaying and blending perfectly with the full-color image. This increases the number of steps in image production, requires higher equipment precision, and significantly raises production costs. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a white ink heat transfer film that can impart a metallic luster to printed materials. It enables the white ink heat transfer film to have the property of imparting a metallic luster to printed materials without affecting the display of the printed pattern.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a white ink heat transfer film that can impart a metallic luster to printed materials, comprising a base film layer, a release layer, a metallic luster layer and an ink-absorbing layer, wherein the base film layer, release layer, metallic luster layer and ink-absorbing layer are sequentially sprayed and superimposed.

[0005] The metallic color layer includes a reflective layer and a transparent color layer, with the transparent color layer disposed on the reflective layer.

[0006] Each reflective layer is provided with multiple pyramidal protrusions and multiple pyramidal grooves.

[0007] The ink-absorbing layer includes a high ink-absorbing underlayer and a smoothing layer, with the smoothing layer placed on the high ink-absorbing underlayer.

[0008] The thickness of the release layer is 0.5-1.0 μm.

[0009] The thickness of the metallic color layer is 3-5 g / m².

[0010] Compared with the prior art, the present invention has the following beneficial effects: This invention relates to a white ink heat transfer film that can impart a metallic sheen to printed materials. By first setting a metallic sheen layer and then spraying an ink-absorbing layer, the composition and structure of the ink-absorbing layer of the white ink printing film are changed, enabling the white ink heat transfer film to impart a metallic sheen to printed materials without affecting the display of the printed pattern. This reduces the need for subsequent hot stamping and lamination processes, improves production efficiency, eliminates the need for high-precision equipment for overprinting, and lowers production costs.

[0013] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0014] like Figures 1-3 As shown, this embodiment provides a white ink heat transfer film that can impart a metallic sheen to printed materials. It includes a base film layer 1, a release layer 2, a metallic sheen layer 3, and an ink-absorbing layer 4. The base film layer 1, release layer 2, metallic sheen layer 3, and ink-absorbing layer 4 are sequentially sprayed and stacked. By first setting the metallic sheen layer 3 and then spraying the ink-absorbing layer 4, the composition and structure of the ink-absorbing layer 4 of the white ink printing film are changed, enabling the white ink heat transfer film to impart a metallic sheen to the printed materials without affecting the visibility of the printed pattern. This reduces the need for subsequent hot stamping and lamination processes, improves production efficiency, eliminates the need for high-precision equipment for overprinting, and lowers production costs.

[0015] Furthermore, the metallic color layer 3 includes a reflective layer 5 and a transparent color layer 6, with the transparent color layer 6 disposed on the reflective layer 5. Specifically, the reflective layer 5 is an aluminum powder coating, and the transparent color layer 6 can be customized with metallic colors as needed. The reflective layer 5 can enhance the brightness and uniformity of the metallic luster, providing a richer selection of metallic colors to meet personalized design needs.

[0016] Furthermore, each reflective layer 5 is provided with multiple pyramidal protrusions 7 and multiple pyramidal grooves 8. The arrangement of multiple pyramidal protrusions 7 and multiple pyramidal grooves 8 increases its reflective surface, and since the pyramidal protrusions 7 and pyramidal grooves 8 have different structures, their reflection conditions are different, which can enhance the reflection effect.

[0017] Furthermore, the ink-absorbing layer 4 includes a high-absorbency underlayer 9 and a smoothing layer 10, with the smoothing layer 10 placed on top of the high-absorbency underlayer 9. The high-absorbency underlayer 9 provides rapid ink absorption and prevents smudging, while the upper layer provides a smooth surface to improve print resolution and color vibrancy.

[0018] Furthermore, the thickness of release layer 2 is 0.5-1.0 μm. A thin release layer 2 can reduce material costs and improve peel performance.

[0019] Furthermore, the thickness of the metallic color layer 3 is 3-5 g / m². A thicker metallic color layer 3 can enhance the metallic texture.

[0020] The foregoing has shown and described the basic principles and main features of this invention, as well as its advantages. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications can be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
